Problem Statement: How is water component treated in the BLOWDOWN Analysis tool in Aspen HYSYS V9 and V10? | Solution: The default program handling of water has changed in V10.0 compared to V9.0.
In V9.0, BLOWDOWN does not have the ability to handle accurately the aqueous phase. Water is automatically mapped when present in every BLOWDOWN analysis and by default assumed to be miscible in the hydrocarbon phase.
Excessive water in the system breaks this assumption and can lead to thermodynamic flash errors and other convergence problems.
As a general practice, we recommend removing all water from the BLOWDOWN initial inventory before running the analysis. Experiments have shown that water is largely an inactive bystander in the depressurization analysis. Removing water also has the advantage of providing the most conservative temperature predictions.
In V10, water is by default removed from the BLOWDOWN component list. A message on the Mapping tab notifies the user of this:
This BLOWDOWN analysis is partially accurate and just consider the system without any water.
Note: This could also be done in BLOWDOWN V9.0 by removing water from the mapped components, obtaining the same result as above.
If user would like to include water in the analysis, the component must be manually added to the BLOWDOWN component list by clicking on the Edit Map button on the Mapping tab. Note that doing so assumes that water is miscible in the hydrocarbon phase, and it is not recommended to make this assumption for previously stated reasons.
Alternatively, a free water option has been added to V10.0. This option can be enabled by checking the box Global Free Water Phase on the System tab.
If this option is checked, water does not appear on the BLOWDOWN component list, and a message on the Mapping tab indicates that free-water assumption, which enables the free water phase to be considered for the analysis.
Keep in mind that the BLOWDOWN Analysis tool is intended for depressurization of hydrocarbon systems. It should not be used to analyze the blowdown of full-water systems.

Problem Statement: Is it possible to use SPYRO pyrolysis kinetics with Aspen Plus? | Solution: Aspen Plus offers EOSPYRO available in a USER3 model to be linked with an externally generated file via the SPYRO program. The SPYRO program, which has pyrolysis kinetics, is a separate program licensed by Technip (formerly KTI). Aspen Plus does not have this kinetics within its databases.
Note 1: Starting on V11, Aspen Plus is now a 64-bit program. It is possible to use 32-bit SPYRO 6 from 64-bit Aspen Plus using a wrapper interface file which is included with Aspen Plus. To use 32-bit SPYRO, ensure that SPYRO is not installed inside the C:\Program Files folder, as this folder is only available to 64-bit programs.
This wrapper slightly changes the interaction with SPYRO, and some changes in configuration files are needed. A new line in the file for SPYRO Subr Path is needed in the .CFG file (see below), and the Furnace Config File line has to include the full path to the file. In addition to this, in the rtopt.opt file, remove the entire line referencing USRKTI.dll. See Using SPYRO section on the Help Guide.
SPYRO Subr Path = <string>
The full path to the folder containing USRKTI.dll. This is only needed to use 32-bit SPYRO from 64-bit Aspen Plus.
Example: USRKTI.dll is installed as C:\Spyro\Spyro6\USRKTI.dll and the line should read:
SPYRO Subr Path = C:\Spyro\Spyro6
Note 2: With the Aspen Plus V11 Cumulative Patch 1 (CP1), the USER3 model SPYRO interface has been enhanced to include support for KS7 kinetics (original component slate only) available in SPYRO 7.
The enhancements to the Aspen Plus SPYRO interface have been implemented and tested using a preliminary (unreleased) version of SPYRO 7. The correct functioning of these enhancements is contingent on the availability of the appropriate version of SPYRO 7 on the userβs computer.
Note 3: The implementation for V11 and V12 was for the preliminary SRTO7 (7.7.6 and before). The support for SRTO7.7.7 and later was added for V12.1 and higher.

Problem Statement: What is the procedure to delete a record from Aspen InfoPlus21 database? | Solution: This article describes about the detailed procedure to delete any record from Aspen InfoPlus21 database.
Due diligence should be taken before deleting any record (specially device records or tag records). The reason being, once a record is deleted from the database, the deletion is permanent and cannot be reverted.
After deleting any record from database, it is not necessary that recreation of the record with same name will also use the same record ID that was used earlier. Hence, the history data associated with the tag record could not be read as history would be stored using record ID.
Important note: Even when the tag record is deleted from the database using below procedure, the history data still remains within the database. There is no straight forward method to read the history data of the tag, once it is already deleted from the database.
Below is the procedure to delete a record from database:
a. Stop the archiving process for the tag. Remove the historian name from IP_REPOSITORY and turn OFF the IP_ARCHIVING.
b. Remove the reference for records. Right click on the tag name and select remove references.
c. Make the tag unusable, once the references are removed successfully. Right click on the tag name select make unusable
d. Delete the tag. Right click on the tag and select delete.
The above procedure will delete the tag from database.

Problem Statement: How to simulate freezing in an Aspen Plus simulation? | Solution: There are two ways to simulate freezing in a simulation:
1. Use the Reaction Chemistry to handle the formation of the solid as a salt precipitation reaction with appropriate K-Salt.
2. Use the RGibbs unit operation block to calculate the solid phase equilibrium.
Chemistry Method:
Aspen Plus can handles formation of a solid as a salt precipitation reaction with an appropriate K-Salt.
The Electrolyte Wizard can be used to include ice formation as a reaction by checking the Include ice formation box under Options. Then, the component ICE(S) of component type Solid will be added to the component list, and a Salt reaction with K-Salt parameters will be added to the Chemistry:
Reaction
Type
Stoichiometry
ICE(S)
Salt
ICE(S) <--> H2O
ln (Keq) = -62.705 + 1681.4/T + 10.317 ln (T) + -0.004851 T
T in Kelvin
An example of using Aspen Plus to predict the amount of ice formed at different temperatures for a 18 wt. % Methanol-WaterSolution is attached. Note that there are no ions in this system.
The freezing point of a 18% methanol-waterSolution is -11.13 C from the Handbook of Chemistry and Physics, 52nd ed., p. D-198, and the freezing point predicted by Aspen Plus is about -11.8 C.
Ions do not have to be part of the system and any solid can be used instead of the water/ice system with the appropriate equation for the equilibrium constant. This method can also be used to predict solubilities (seeSolution 102340 for an example). Note that K-SALT and activity coefficient model parameters are not independent of each other.
The true component approach should be used in order to see the solid in the stream results.
The advantage of this method is that the solid equilibrium is evaluated for every stream and in every unit operation block.
RGibbs Method:
RGibbs can be used to calculate solid phase equilibrium (e.g. ice forming from water). To do this, give the solid a different component ID - this tricks the RGibbs block into thinking it is doing chemical equilibrium instead of phase equilibrium (SeeSolution 102346 for an example).
RGibbs can even handle solidSolutions (alloys). RGibbs can be used for much more complex applications that the Chemistry method discussed above.
NOTE: Phase equilibrium calculations between solids and liquids rely on accurate calculation of the Gibbs Free Energy for both phases. A small difference in Gibbs Free Energy calculations can cause Aspen Plus to predict a melting temperature far from reality. Phase equilibrium should be verified for the components and Physical Property models of interest before relying on the predictive capability of RGibbs.
RGibbs bases its prediction on pure component properties and should not be used to predict solubilities.

Problem Statement: We have two process streams (X and Y) which mix and can only do so up to a fixed maximum ratio. Ratio can be variable depending on the absolute flow of Stream A. Stream A is a different LP column which is not itself part of the ratio control row but is present somewhere else in the same LP submodel. When Stream A is at low rates, then this ratio increases and when Stream A is at higher rates then this ratio decreases; therefore, in summary the max ratio depends on the flow rate of Stream A.
Is it possible to create such structure in DR? | Solution: For AO this problem can be modeled easily using Non-linear Equations tool.
In DR we could try to resolve this issue involving PIMS-SI (in case youβre not planning to migrate to AO. Non-linear formulas are preferable still. Please note SI is not supported in AO).
For example, there is fixed ratio between two variables introduced β row Enewnew in ROWS (in your case it could be either G or L row) and want to vary that coefficient for DCN (now it is 5)
The following workflow could be used for control:
Define Excel Server
Define necessary independent variable as an Input (I defined SHCDBAS β random choice). Value will be populated from PIMS to Simulator
Necessary non-linear correlations can be defined in a separate spreadsheet. I used IF operator for testing
Result of calculation I would like to use as mentioned coefficient, so as an Output I specify the value should be used in PIMS for coefficient in the intersection of row Enewnew and SNHTDCN.
After run I can verify coefficient is changing dependent on SHCDBAS activity.

Problem Statement: When connecting Aspen Verify to PIMS result database customer get the message βInvalid object name 'prcase' during SQL server connection. | Solution: There is a requirement for PIMS databases collation to be set as case-insensitive (that will be noted in the documentation starting from V14). Please note PIMS database script does not specify the collation attribute but takes the default collation that has been set in SQL Server. The default collation value is determined from the operating system locale. Look at the Server-Level Collations section in the link https://docs.microsoft.com/en-us/sql/relational-databases/collations/collation-and-unicode-support?view=sql-server-ver15#Locale_Defn
In that scenario where the default collation value is a case-sensitive one, then the user will need to specify a case-insensitive collation value in the PIMS database script. If the user manually creates the PIMS database, then the collation value needs to be a case-insensitive one.

Problem Statement: Problem reports from customers indicated that the previous Aspen Cim-IO Store-and-Forward functionality was not very reliable, sometimes failing to complete, or forwarding very slowly β problems not reproducible in-house. Consequently Aspen Technology replaced the overly-complex Aspen Cim-IO store-and-forward architecture with a more reliable mechanism for the temporary buffering of data to be sent to the Aspen Cim-IO client after connectivity has been re-established. | Solution: Reason for Store-and-Forward
Under some circumstances, the Aspen Cim-IO server software is capable of collecting data from the device, but the data cannot be transferred to the Aspen Cim-IO client application, resulting in a loss of historical information. Aspen Cim-IO Store and Forward was designed to allow for recovery under the following situations:
The client that requested the data is shut down or otherwise unable to receive data, or
The connection between the server and client computers is lost.
When the server determines that one of these conditions applies, Aspen Cim-IO Store and Forward accumulates the time-stamped data as it is collected. Once it becomes possible to return to normal operations, Store and Forward sends the accumulated data to the client.
How previous Aspen Cim-IO S&F mechanism worked
The Store and Forward system consists of three processes on the Aspen Cim-IO server computer:
Aspen Cim-IO scanner process
Aspen Cim-IO store process
Aspen Cim-IO forward process
If Store and Forward is enabled, the Scanner functions as an intermediary between the client and the DLGP. If the client is unavailable or the link is broken, the Scanner keeps sending the clientβs data requests to the DLGP.
The Store process receives data from the DLGP. If the client is unavailable, the Store process writes the data to a store file until normal data transfer can be reestablished.
When normal data transfer is available after an interruption, the Forward module begins sending the contents of the store file to the client. This process continues until the file is emptied. The Store process continues writing data to the store file until the Forward process empties the store file. Afterwards, the Store process resumes communications with the client task.
Improved Aspen Cim-IO S&F mechanism
AspenTech re-implemented Store & Forward by exploiting the same kind of queuing mechanism that has been used for several decades by the Aspen InfoPlus.21 history event queue, a mechanism that has proven to be very reliable.
A key simplification is that the Aspen Cim-IO interface processes no longer have to coordinate switching between normal mode, store mode, and forwarding mode. Instead, if store and forward is enabled, all data passes through the queue before being sent to the Aspen Infoplus.21 system.
If the Aspen InfoPlus.21 is inaccessible, then new process data simply accumulates in the queue until one of the following conditions occurs.
Connectivity between the client and server is re-established. Data removed from the queue is then forwarded on to the client.
Data packets in the queue have been in the queue too long, violating a configurable maximum time limit. Aspen CIM-IO simply dequeues and discards data packets that are older than the specified limit.
The queue has grown too large, violating a configurable maximum size. The Aspen Cim-IO store and forward process dequeues and discards the oldest data packets as necessary.
Aspen Cim-IO S&F Configuration
Aspen Cim-IO store-and-forward parameters are specified for an interface using the Cim-IO Interface Manager.
Expand the tree control in the left hand pane until you find the Aspen Cim-IO interface instance of interest. Selecting the interface instance causes the middle pane to show information about the interface instance.
You will be able to:
Enable Aspen Cim-IO store-and-forward. Enabling store-and-forward causes the disk overflow queue to be created. It also causes the scanner process and the Aspen Cim-IO store and forward process to run.
Disable Aspen Cim-IO store-and-forward. Disabling store-and-forward stops the scanner process, stops the Cim-IO store and forward process, and deletes the store and forward disk overflow queue.
Set maximum time limit for data in queue. The Aspen Cim-IO store and forward process automatically discards messages that have been in the queue longer than the maximum time limit. The default is 72 hours.
Set size of the store and forward disk overflow queue file storage. In order to avoid disk fragmentation, improvement performance, and guarantee that desired disk space is available when needed, the disk overflow queue files should be created automatically in advance of need. If you specify the total disk overflow queue size, then Cim-IO will automatically create five disk overflow queue files, with each file sized at 20 percent of the specified total.
For example, if specified queue storage is 1 GB then five 200MB files would be created. If all five files become full (because of extended outage), then the data in the oldest file would be discarded; that is, no more data would be stored than can be accommodated by the pre-allocated storage.
If the user fails to specify a queue storage size, then one file is created when needed (ie., when primary and secondary memory sections are full), similar to the Aspen InfoPlus.21 history event queue.

Problem Statement: At Calibrate mode, the RAMP variables will be deviated from ramp setpoints, regardless of Ramp Rate values or test group's mode (even the test group in Control mode). This document will introduce the reason and workaround. | Solution: This behavior is by design, RAMP variables will not be balanced in Calibrate mode (even if a test group is in Control mode). This is due to the concern that frequent actions were taken by ramp handle MVs will intervene with other variables still in Calibrate mode and degrade the data quality for modeling.
From V10.0 CP2 version, there is a new Calibrate mode CALIBOPT=1, the Calibrate Ratio determines the allowable deviation of each MV from its ideal target (when Calibrate Ratio is 0). This affects how much each MV can step away from the optimal value. For each MV, the allowable deviation from the optimal target is determined by the smaller of STCTLSTRATIO*(ULINDM-LLINDM) and STMVMAXSTEP.
Users can specify how much each variable can step away from its optimal target. For MV, clamp its Operator Limits or decrease STMVMAXSTEP can make it moving nearer to its optimal target. For CV, specify its handling MVs can get similar effect.

Problem Statement: In an output file for an Aspen InfoPlus.21 external task what does this message mean?
Error : Invalid external task record - 481 | Solution: This means that the task in question does not have a corresponding record in the database. The missing record is needed in order for the task to function correctly. In the example screenshot above, the external task called TSK_IQ3 is producing the error. Notice that the task is NOT running (no check mark in the box to the left of the task name in the Defined Tasks list in the Aspen InfoPlus.21 Manager). The problem may be fixed either by creating a new ExternalTaskDef record with the same name as the task (in our example: TSK_IQ3) or by duplicating a similar record, like TSK_IQ1, and giving the duplicate the name of the task (in our example: TSK_IQ3).
Before:
After:
Now, with the new, corresponding ExternalTaskDef record TSK_IQ3 in place the TSK_IQ3 task can start and run successfully:

Problem Statement: After applying the CP1 patch for V11 in the Online server, the controller fails to deploy. When deploying, an error message appears saying to check various items but all of them look correct. | Solution: The problem occurs when there are V11 EPβs applied in the Online server and CP1 is applied above. On the other hand, this does not happen if CP1 was applied on a V11 installation with no EPβs.
The installer fails to update the ACESAppTemplate.xml file to the CP1 version, leaving the EP version. Therefore, the engine recognizes the version of the ACESAppTemplate does not match with CP1, and outputs an error message when trying to deploy the controller.
The workaround is to replace the attached ACESAppTemplate.xml. Here is the procedure:
Close all DMC3 Builder windows in the Online server (DMC).
Stop all the RTE controllers.
Stop the RTE service
Replace the attached ACESAppTemplate.xml file in the following locations.
C:\Program Files (x86)\AspenTech\APC\V11\Builder
C:\Program Files (x86)\AspenTech\RTE\V11\APC.
If you get an error βaccess deniedβ, make sure to log in with an administrator account, and copy the xlm file into the server and then to the locations mentioned.
Restart the RTE service. The application should deploy successfully.

Problem Statement: When designing basic phases in a BPL all the variables you define are internal to the phase (their values at execution cannot be accessed from another basic phase) except for Recipe Global variables. These variables once defined in any basic phase can be later used in another basic phase, as parameters in the recipe (RPL) design or inside PFC condition definitions.
The format of Recipe Global variables is as follows:
$$<name> where name is the variable name
If you include any arithmetic symbol in the name of the global variable (for example, $$IP-21), the variable cannot be used without causing syntax errors on compilation or execution. | Solution: The symbols +, -, / and * are not allowed in the global variable names. Any access (read/write) to global variables is in the script code and these symbols are reserved tokens for arithmetic operation in the script. With these symbols in the variable name, and then included in the script code, the compiler is triggered to throw a syntax error in the compiling process.
Consequently, the use of such symbols in the global variable names is not supported.

Problem Statement: Recent versions of aspenONE Process Explorer (A1PE) feature several performance improvements that address the slow performance issue when communicating with remote Aspen InfoPlus.21 (IP.21) systems across a wide area network (WAN) instead of accessing an IP.21 system that is on the same local area network (LAN).
This article describes the background to this issue and how to configure the A1PE web server to take advantage of performance improvements in recent versions of A1PE. | Solution: The underlying cause of poor A1PE performance when communicating with a remote Aspen InfoPlus.21 (IP.21) system across a wide area network (WAN) instead of accessing an IP.21 system that is on the local area network (LAN) is explained below.
A1PE obtains process data from an IIS-based Process Data REST Service. The Process Data REST Service obtains the requested process data from the specified data source, which may be on a different computer. The Process Data REST Service establishes a connection with the remote IP.21 system when the user first opens a graphic or trend plot to view process data from that IP.21 system. This initial establishment of a connection is usually fast (seconds) if the IP.21 server is on the same LAN as the Process Data REST Serviceβ¦but it may be quite slow (minutes) if the IP.21 server is somewhere more remote. Once a connection has been established, then subsequent graphic or trend plot invocations are fast.
The Process Data REST Service makes calls to a local COM-based component (dll) - the IP.21 Data Server. When establishing an initial connection to an IP.21 system, the IP.21 Data Server component makes many calls to a lower-level IP.21 Application Programming Interface (API). These lower-level calls take much longer across a WAN because of the poorer speed and latency characteristics of a WAN.
The improvement provided here exploits an already existing Aspen Process Data Service (a Windows service) that already resides on the InfoPlus.21 system for use by the Process Data Excel Add-ins. If configured to do so, the Process Data REST Service (a web service) will communicate with the Process Data Service (a Windows service) that resides on the same computer as IP.21. The Process Data REST Service makes relatively few, high-level calls to the Process Data Service. The Process Data Service invokes methods in a local IP.21 Data Server. When establishing an initial connect, the IP.21 Data Server still makes many calls to the lower-level IP.21 APIβ¦but in this scenario, the calls execute much faster because they are not occurring across a WAN.
A1PE users who need to access remote Infoplus.21 systems can enable this performance improvement by making both an ADSA configuration change and an AtProcessDataREST.config change.
The ADSA change required for this WAN performance improvement is to add βAspen Process Data Serviceβ to the ADSA data source for the IP.21 system:
To obtain this WAN performance improvement, you would also need to edit the AtProcesssDataREST.config file, setting the UseProcessDataService parameter to True.
File: C:\inetpub\wwwroot\AspenTech\ProcessData\AtProcessDataREST.config
<REST>β¦<UseProcessDataService>True</UseProcessDataService>β¦</REST>
So, in summary, the Process Data Service is used:
β’ Only if the entry in configuration file is set to True
β’ Only for data sources configured with the Aspen Process Data (IP.21) service
β’ Only for data sources configured with the Aspen Process Data Service
β’ Only valid for the REST systems that talk to InfoPlus.21 servers of the same or newer version
β’ Only if the IP.21 system is on another machine (hostname in Process Data Service is NOT the same as the Web Server)
Users who do not make these changes would not benefit from the performance enhancement that applies when the InfoPlus.21 system is remote.

Problem Statement: This article aims to explain a known defect in DMC3 Builder's prediction plots display of the data range dates and times when multiple datasets are selected, so that users are aware of the issue when viewing prediction results. The target fix for this issue is V14 (Defect 600435). | Solution: When running predictions from a case that has multiple datasets added with different dates, the original dates of the datasets are not being preserved in the predictions graph data range but instead, they are tied together as segments of a continuous dataset. So for example, two datasets were added to a case with the following ranges:
June-12-2014 to July-7-2014
July-14-2014 to August-20-2014
In DMC3 Builder > Case Editor > Variables > Dataset section:
After running identification and viewing the Prediction results, one would expect to see the range of both datasets from Jun 12 to Aug 20. However, the data range shows from June 12 to August 7, as seen below:
This may seem like the full datasets are not being used for the prediction results, however, this is just a display issue and both datasets are still being used. The reason for this behavior is because the dates from the second dataset are not being preserved accurately. Instead of ranging from June-12 to July-7 (first dataset) and then July-14 to August-20 (second dataset), the dates are combined together as if it were one continuous dataset. Since the Jun-12 dataset was added first in the list in the Case > Variables section, that is the date used as the starting point for the data range and the second dataset is added as a continuation of it.
As a workaround, the user can create a copy of the case for just viewing predictions and use one dataset at a time in the case to view the prediction results.

Problem Statement: How to see the results for the assay D2887 in the Workbook when those are empty? | Solution: For seeing the results of D2887 assays do as follows:
1. Double click on the empty value.
2. Go to Results.
3. Change basis to Mass Frac.
4. Repeat the previous steps for all the D2887 Assays columns.
For oil characterization, the ASTM 2887 is a simulated distillation curve generated from chromatographic data, the resulting curve is reported on a weight percent basis. Thus, the D2887 assays are always on a mass basis, therefore there are no means to get those results in a volume or mole basis
For more information about the ASTM 2887 characterization, please refer to the KB article below.

Problem Statement: In versions prior to V12.1, the IQ Help File is not clear on the behavior of the Cusum Update Method. This article aims to elaborate on this topic.
Currently, the description that needs further explanation under the Aspen IQ Users Guide > Aspen IQ Modules > Lab Update (LBU) Module page > section on the CUSUM Update Method is as follows:
When the accumulated error is greater than the limit, then the number of lab values that were required to provide the necessary total error for an update is used as the number of lab values in the raw bias update calculation.
An update will occur when the number of samples specified in LBUNUMVALS is reached, regardless of what the CUSUM counter says. This approach allows you to be assured of a lab update after a certain number of lab samples, but if an update is required before that, then it will be performed.
Note: In version V8.8 and later, no automatic bias update occurs when the number of samples reaches LBUNUMVALS. Additionally, there is no longer a requirement that LBUNUMVALS samples must be entered before the first bias update occurs. | Solution: The above description in the Help File can be clarified as follows:
When the accumulated error is greater than the LBUCUSUMLIM threshold, a lab bias update will occur. The number of lab samples that will be used in this raw lab bias update calculation is determined as the minimum of either:
The number of lab samples that were required to provide the necessary total error that met the LBUCUSUMLIM
The number of lab samples equal to LBUNUMVALS
An update will occur as long as the LBUCUSUMLIM threshold is met, even if there are fewer than LBUNUMVALS good samples available.
If LBUCUSUMLIM is exceeded using number of samples less than LBUNUMVALS, then number of samples required to meet the threshold will be used for lab bias update calculation.
If LBUCUSUMLIM is exceeded using number of samples greater than LBUNUMVALS, then LBUNUMVALS will be the number of samples used in the raw bias update calculation.
Note: In version V8.8 and later, no automatic bias update occurs when the number of samples reaches LBUNUMVALS because the bias update requires that the accumulated error is greater than or equal to LBUCUSUMLIM first. Additionally, there is no longer a requirement that LBUNUMVALS samples must be entered before the first bias update occurs.

Problem Statement: How can I find the Engineering Drawings included on for my Aspen Capital Cost Estimator project? | Solution: Aspen Capital Cost Estimator (ACCE) can estimate a quantity of Engineering Drawings, which contribute to the Engineering cost of the project.
The available drawing types correspond to the Basic Engineering and Detail Engineering phases of the project. ACCE reports these results in separate tables, each one corresponding to each of these phases.
The calculated Engineering Drawings can only be seen on the CCP report, a drawing count table will be generated for each contractor that will perform Basic or Detail Engineering. Search for the label βDRAWING CATEGORYβ to find them easily
BASIC ENGINEERING DRAWINGS:
DETAIL ENGINEERING DRAWINGS:
Note you will see one table for Basic Engineering drawings and a second table for Detail Engineering. These tables are not immediately next to each other.
Keywords: Drawings, Sketches, Diagram, Indirects, Count

Problem Statement: How do I create and modify an Engineering Workforce? | Solution: Aspen Capital Cost Estimator (ACCE) allows to customize the Engineering Workforces (EWF) that will participate in the project, allowing to create additional teams, and to edit the cost and hours of each engineering discipline.
Engineering workforces can be customized from the Engineering | By Phase and Engineering | By Discipline forms, both can be used simultaneously to provide all the details for each Engineering team.
Using the By Phase form:
Allows for general adjustments to engineering teams. Control data for All Engineering Phases or for a single Phase (i.e. Basic Engineering)
Specify an Engineering Workforce number. A blank value is allowed (Default EWF). Multiple columns can have the same number, each column representing a different adjustment to the same EWF.
Specify an Engineering Phase (i.e. Basic Engineering). If multiple phases will be modified, each should be selected on a different column.
Enter your own engineering cost and hours to overwrite the system calculations OR apply percent adjustments to the calculated hours and wage rates. (Default Wage rates shown in Icarus
Keywords: Engineering, Crews, Cost, Proratables, Indirect, Wage Rates,
References: , Chapter 31).
If desired, enter additional changes such as payroll burden, indirects, and expenses for the selected phase (lump sum or percentages available)
Add more columns to the form to define more Phases
The order of the Columns matters:
Do not use the β * - All Phasesβ option after defining a single phase (i.e. Basic Engineering) in the same EWF, since the All Phases data will overwrite the adjustments done for Basic Engineering.
Define All Phases before the single phase (i.e. Basic Engineering), this way the global adjustment is applied to all phases and only the Basic Engineering will receive the second modification.
Using the By Discipline form:
Allows for detailed adjustments to engineering. Control data for individual Disciplines (i.e. Piping Design) thatβs part of an Engineering Phase (i.e. Basic Engineering)
Specify an Engineering Workforce number. A blank value is allowed (Default EWF). Multiple columns can have the same number, each column representing a different adjustment to the same EWF.
Specify an Engineering Phase (i.e. Basic Engineering). Same Phase can be added to multiple columns if multiple disciplines will be modified.
Specify an Engineering Discipline (i.e. Piping Engineering).
Enter your own engineering wage rate and hours to overwrite the system calculations OR apply percent adjustments to the calculated hours
Add more columns to the form to define more adjustments.
The order of the Columns matters:
Do not use the β ** - All Disciplinesβ option after defining a single discipline (i.e. Piping Design) in the same EWF, since the All Disciplines data will overwrite the adjustments done for Piping Design.
Define All Disciplines before the single discipline (i.e. Piping Design), this way the global adjustment is applied to all disciplines and only the Piping Design will receive the second modification. This is showcased on the screenshot above.
Note in order to use a different EWF other than the default, the workforce should be linked to a contractor. According to the Contractorβs task, their information will be used. |
Problem Statement: How can I control the Rental Equipment on my Aspen Capital Cost Estimator project? | Solution: Aspen Capital Cost Estimator (ACCE) provides a field to control the Rental Equipment (ER) to be included on the estimate.
In order to fully control all the ER it is important to first review the results generated by ACCEβs system, since the Equipment Rental form will allow to:
Add equipment, if itβs missing and should be included
Delete equipment, if it should not be included on the estimate
Change the required days or fees for an equipment.
For details on how to find the System Generated results please review Article 76965
Once you have identified the Equipment that will be modified, navigate to the Equipment Rental form in the Project Basis View tab. For each modification you would like to perform, add a new column to the form.
To add an equipment rental:
Enter a description (i.e. Include Ambulance)
Select the Contractor(s) that will assume this cost
Enter the Equipment Rental Number β this is a value unique to each rental service that can be estimated in ACCE. Review the list of Numbers on the Icarus
Keywords: Rental, Equipment, Remove, Include, Change, Fees, Duration, Adjust, Overwrite
References: guide, chapter 32 Construction Equipment (i.e. 21 for Ambulance)

Problem Statement: This article assumes there are no apparent problems with search in aspenONE Process Explorer (A1PE) when Domain Security is disabled.
After having used aspenONE Credentials tool to configure aspenONE search so that Domain Security is enabled, you may see multiple signs of poor performance when using search within A1PE, likely timeout messages are recorded in log files (see ProcessDataRestService logs in C:\ProgramData\AspenTech\DiagnosticLogs\ProcessData folder -and- various logs in \<Tomcat>\logs folder). You may also see status errors displayed when working with the aspenONE Process Explorer Admin page.
Errors reported may include some, if not all (at some time) of the following:
Unable to validate server response. HTTP Code: 415 Description: The initialization procedure that runs the first time the Search Engine connects to its configured domain has not completed. Please try again later.
Unable to validate server response. HTTP Code: 504 Description: Search Security experienced a connection timeout when connecting to your domain. Serverβs aspenONE Credentials tool can be used to increase connection timeout.
Because of the timeout errors, you should at least see if increasing the Connection and Read timeouts in aspenONE Credentials tool resolves the problem (after having restarted Apache Tomcat). If this does not resolve all issues adequately then continue with the | Solution: described below.
Background: When Domain Security is enabled, the Search Engine will tailor the search results to only the items to which the user has read access based on the userβs group membership (group used in AFW Local Security to define Role holding Read Privilege). To improve general performance, aspenONE caches all the domain groups and users so it doesnβt have to check in with the domain on each search request. This initialization should complete quickly unless it either cannot access the LDAP service or the number of domain group and users configured in the Active Directory Domain is very large (perhaps even measured in the hundreds of thousands).
At this point you should at least verify the credentials specified in the aspenONE Credentials tool are valid.
Assuming that indeed the problem is likely caused by a large number of user objects in your Active Directory Domain, thisSolution will describe how you might resolve these errors whilst keeping Domain Security enabled.Solution
For V11 and V10.1:
Apache Tomcat has been installed as a 64-bit service. For 64-bit Apache Tomcat, open the TomcatNw.exe application in %PROGRAMFILES%\Common Files\AspenTech Shared\<Tomcat>\bin folder (where N = Tomcat version number) to increase the Initial and Maximum Java memory pool to 2048 and 4096 respectively (decide on values depending on actual system memory availability):
For V12 and V14:
For versions starting with V12.0, you should follow the instructions in the following KB: https://esupport.aspentech.com/S_Article?id=000101489 βMonitoring and Tuning Solr Memory Consumptionβ for updating memory allocation.
Perhaps having made these changes, even at this point you will benefit from sufficient improved performance and consequent reduction of error messages.
You can modify the behavior of aspenONE so it only caches a subset of the domain groups and users (instead of ALL of them which is the default until at least V14.0). To do this follow appropriate sets of the following instructions:
A. If aspenONE Process Explorer web server is V12.0+ then solr is installed in its own part of the file system: %PROGRAMFILES%\Common Files\AspenTech Shared\solr-N.N.N (solr-8.2.0 for aspenONE V12.0 to V14.0 but likely will be different in due course):
Stop SolrWindowsService in services.msc
Stop Apache Tomcat service in services.msc
Delete the existing Solr Security Database by deleting all files and folders found under \<solr>\server\solr\aspenTech\conf\derby\
Open a text editor (Run as Administrator) and select file: \<solr>\server\solr\aspenTech\conf\AspenSearchSolrSecurity.xml
There are 3 new Boolean switches available since V10.1; in each case setting the value to true will enabled the feature.
OmitDomainUsersGroup β Prevents connection to Domain Users Group at level defined by ldapBase. This connection is required for Domain Security.
UseSeededDataOnly β Build security cache from Process Data response instead of building full Active Directory cache.
SkipPrefetch β Skip initial load from Active Directory the first time SOLR starts.
To enable all these features, add the following lines (carefully inserted just before the closure of the lst section) and then save AspenSearchSolrSecurity.xml file:
<bool name=omitdomainusersgroup>true</bool>
<bool name=useseededdataonly>true</bool>
<bool name=skipprefetch>true</bool>
At this point, the Tomcat log files are obsolete given the configuration changes made so you may like to consider moving or deleting the contents of the log folder: %PROGRAMFILES%\Common Files\AspenTech Shared\<Tomcat>\logs\
Restart Apache Tomcat service in services.msc
Wait for \<Tomcat>\logs\AspenSchedulerStartUp.log to appear
Also wait for \<Tomcat>\logs\SolrFacadeStarup.log to appear
Restart SolrWindowsService in services.msc
Go to RESCAN section below
B. If aspenONE Process Explorer web server is V10.1 to V11.0 then solr is installed within <Tomcat> part of the file system:
Stop Apache Tomcat service in services.msc (this is very important and Tomcat configuration files could become corrupted if you continue making these changes whilst Tomcat is running).
Delete the existing Solr Security Database by deleting all files and folders found under \<Tomcat>\appdata\solr\derby\ - Note, there are two derby folders in the appdata area of the file system: DO NOT MODIFY ANY OTHER THAN THE ONE FOUND UNDER SOLR FOLDER.
Open a text editor (Run as Administrator) and select file: \<Tomcat>\appdata\solr\collection1\conf\AspenSearchSolrSecurity.xml
There are 3 new Boolean switches available since V10.1; in each case setting the value to true will enabled the feature.
OmitDomainUsersGroup β Prevents connection to Domain Users Group at level defined by ldapBase. This connection is required for Domain Security.
UseSeededDataOnly β Build security cache from Process Data response instead of building full Active Directory cache.
SkipPrefetch β Skip initial load from Active Directory the first time SOLR starts.
To enable all these features, add the following lines (carefully inserted just before the closure of the lst section) and then save AspenSearchSolrSecurity.xml file:
<bool name=omitdomainusersgroup>true</bool>
<bool name=useseededdataonly>true</bool>
<bool name=skipprefetch>true</bool>
At this point, the Tomcat log files are obsolete given the configuration changes made so you may like to consider moving or deleting the contents of the logs folder: \<Tomcat>\logs\
Restart Apache Tomcat service in services.msc
Wait until you can locate the \<Tomcat>\logs\AspenSchedulerStartUp.log file with a new entry confirming AspenSearchDeployer completed deployment operations. If AspenSearchDeployer does not deploy then see knowledge base article: KB How-to-resolve-aspenONE-Process-Explorer-Admin-status-error-A-connection-with-the-server-could-not-be-established-Error-code-500
Go to RESCAN section below
RESCAN
Regardless of aspenONE Process Explorer web server version, you should now open aspenONE Process Explorer Admin
At this point you will be presented with (red font) status error (Error code: 415):
Ignore the status errors and click the Start Scan button regardless. The scan should commence without error and soon you will see that the status error at the top is replaced by (green font) Search Engine Status : Running and Configured
Once the scan has completed (and assuming no significant errors) you are now ready to test for acceptable performant operation of search throughout aspenONE Process Explorer.

Problem Statement: During conversion process of a Proll file into an Aspen HYSYS; the converter encounters a consistency error related to a value that is been specified and calculated at the same time:
That makes that Aspen HYSYS solver is automatically turn on by design and the Proll Converter turn off it via back door when converting any columns. | Solution: When Aspentech developed the converter, this issue was identified and an option ignore column solving during converting was added, this option reduces the inconsistency error in the test input files (around 100) at that time, so it was decided to not set Aspen HYSYS as on hold in Proll conversion it's better for customers to see many of the Unit Operations calculated successfully after conversion.
Unfortunately, this issue cannot be fixed in Proll converter side. But a workaround is to modify the original INP file by removing an HX to avoid the above inconsistency error. You can use the converted .HSC case as a startup file and add back the HX manually.

Problem Statement: It is common that users want to see results directly in the flowsheet to save time, however, pasting the stream report in the flowsheet might me unnecessary as the desired properties are little, thus a custom table might be the | Solution: .
Solution
Custom table option is located on Flowsheet folder in the navigation pane, there you can create a custom table clicking on new. It will ask you for a name.
Then you can add properties to the table by copying and pasting the properties that you want in the table, or you can use drag and drop the variables that you want to add. The variables can be either inputs or calculated variables.
As you can see the default names in the table are default generic names, you can edit them to identify easier, also the units of the variables can be changed directly in the table.
Finally, this table can be pasted directly in the flowsheet or just as an icon if you want to save space. Also it can be sent to Excel.

Problem Statement: In order to generate templates that show the information we need about the process, we can add properties and change the order in which they are displayed, however, in occasions it is needed to add properties contained in property sets created for the simulation, but the option add Property Set appears disabled. | Solution: Once the property set that is to be used is correctly created and the properties properly defined, then we can go to Setup in the Navigation pane and go to Report Options, then go to Stream tab and finally click on Property Sets.
A window will prompt, there you can select the property sets that you want to add to the stream report, also there you can create a new one in case you have not created any property set before.
Now, when adding more properties to the stream report you will see the Add Report Prop-set available, click on it and it will display the properties added by the property set. This will add the stream report, which you can save as a template and even select it to be used as the default template.

Problem Statement: It is common that customers want to paste the stream report in the flowsheet in order to see the information of the streams faster just looking at the flowsheet. Here it is shown how to do this. | Solution: Pasting the stream report in the template is quite easy, just go to the stream report that you want to paste in the flowsheet and click on Send to Flowsheet option in the Stream Summary tab.
Then it is going to ask you if you want to synchronize the streams I the report, so that it gets updated every time the simulation runs, and if you want to synchronize the template.
After clicking on OK it is going to ask you to save the stream report as a template, so that this template can be edited and customized
Then, the stream report is going to be pasted in the flowsheet as an image, it cannot be edited directly in the flowsheet, but double clicking on it will take you to the stream report.
Besides, remember that you can customize the template clicking on Select Properties in Stream Summary tab, where you can chose what properties will be displayed and even the order to show the properties.

Problem Statement: When using Column internals in order to calculate the hydraulics of the column, it is common to compare the results obtained form the Column Internals results to the results from the Column profile, then a difference is notorious, the reported flows are different.
As it can be seen, the flow reported for stage 4 in Column Profiles is reported in Stage 3 in Column internals, and it can be observed for other stages. | Solution: The explanation for these different values reported by tray is because the values for the vapor are reported with two different approaches, one is Vapor from the selected stage to the previous tray, and the other approach is the vapor to the selected stage.
For instance, observe stage 4, we can see that the flow reported by the column performance is in stage 3 in Column internals results, this is because Colum internals is reported for stage 4, the vapor flow that is flowing to the stage 4 from the upper stage, whereas in Column Profiles, stage 4 reports the vapor flow flowing from stage 4 to stage 3. See the following image.
Besides, remember that there are two different approaches to report the flow in the stages:
Total: Represents all the material balance in the stage, considering draws, pump arounds, side draws, etc.
Net: Represent only the flow that is leaving the stage
Column Internals report Total flows, thus it is going to report different flows if in there are vapor streams associated to the previous stage. Colum Profiles are only going to report the Net flows.

Problem Statement: For some specific reactions, users can specify the heat of reaction according to experimental data, however, when specifying the value it requires a selection of the | Solution: The answer depends on the reference of enthalpy of formation of the components, commonly these values are reported for gases, and to consider the enthalpy of formation of liquids we must substract the enthalpy of vaporization of the component, so that to enter this value you must know the phases in the reactions at the conditions used to measure the heat of reaction. Then the answer is as follows:
Vapor reference
Use this reference if the heat of reaction was measured considering only gases in the reacting system.
Liquid
Keywords:
References: Phase.
Heat of reaction is calculated by the difference of enthalpy of formation of products and reactants multiplied by the stoichiometric coefficient of the components involved in the reaction at standard conditions, and this heat of reaction is considered in the energy balance of the reactor automatically.
However, in some cases this heat of reaction might be different from the value that users are expecting, since users know this value from an experiment, literature or another database, and in those cases it is adequate to specify the heat of reaction, doing this will not affect the energy balance of the RStoic, but the duty, the question is: what reference phase should we use? |
Problem Statement: When creating an Oil Manager blend, it is common to test it in the simulation environment, and in some occasions we can observe problems about the flashing in the results. For instance, in the following screenshot we can see that when mixing the Oil stream with water, the temperature of the mixture decreases too much.
Also, if we analyze the Oil stream, we can see two liquid phases, which can be indicating that something is wrong. | Solution: This problem might be caused by the inputs, although they are not necessarily wrong, they could have caused a problem with the calculations. So we can go to the Properties environment and review the properties of the Blend.
In this case, analyzing the Property Plot tab, we can see how the Critical pressure of the Blend decreases linearly close to the 100% Liquid volume. So, given this evidence we can go to Oil Manger option and go to the Correlation Sets tab, there is a Correlation set create by default, then we can create a new one clicking on Add.
The name of the new correlation set is editable. In this new correlation you can see all the default correlations, just change the Critical Pressure correlation to Rowe.
After doing this, the correlation in Input Assay and in Output Blend options can be changed to the new one, hence, the Assay has to be Calculated again. This will turn the simulation to On Hold mode, just activate again the simulation and the problem about the incorrect results is solved.
The correlation that should be changed depend on the results obtained from the Property plots, and general results of the blend. To review more information about the different correlations that can be used, please go to the Help guide in the section Oil Methods and Correlations.

Problem Statement: Aspen HYSYS V12 Stream Reporter (HSR 1.7.3) | Solution: HYSYS Stream Reporter (HSR) is an Excel spreadsheet utility that allows to import to a spreadsheet the material stream information such as conditions, properties and compositions, and also compare streams from different cases.
HSR can report properties from the following phases: Overall, Vapour, Light and Heavy (Aqueous) Liquid, Combined Liquid and Solid. It also allows stream user variables and property correlations to be reported. It is also possible to create formulae in the output table. The user can save sets of properties or use one of the pre-built property sets. Streams from different HYSYS cases can be reported in the same stream table. Once a stream table has been generated it can be updated by pressing a single button. Stream tables can be moved to another Excel workbook whilst maintaining the ability to be updated.
HSR takes the form of an Excel spreadsheet file with embedded Visual Basic for Applications (VBA) code that demonstrates how HYSYS can be accessed programmatically. The VBA source code is freely accessible and users are encouraged to learn from it and adapt it to their own needs.

Problem Statement: Prior to V10 CP3, there was an inconsistency in the variable status handling for disabled limits. When the Steady-state ECE for both high and low limits are 1.0e+6, the CV status becomes βPred Onlyβ. However, a CV with high and low limit ranks of 9999 would show a status of βNormalβ. From the controllerβs perspective, both CVs would be treated internally as prediction only. In V10 CP3 and later, both scenarios now result in a CV status correctly showing βPred Onlyβ. If the CV is considered critical, then the controller will no longer be able to turn on. Additionally, if the CV is used in a Composite application, you will not be able to turn the variable on for Composite use. | Solution: The workaround to prevent the 'Prediction Only' status would be to enable one of the limits, set the limit to a safe value, and set the rank to something other than 9999.

Problem Statement: This KB article provides guidance for installing the latest CP on a GDOT machine. It also explains on the SLM configuration before and after patch installation. | Solution: When upgrading a GDOT machine to the latest CP, use the following steps:
Launch aspenONE SLM License Manager:
Click on βConfigureβ and βYesβ to the dialog asking if you want to allow this app to make changes. The βSLM Configuration Wizardβ dialog should appear:
Click on βShow Bucketsβ. This launches a dialog that shows the list of available license buckets as well as which buckets are currently active (selected). GDOT will search for a suitable license in the selected buckets. Make sure that the correct buckets are selected. For GDOT this typically means that both the Default bucket is selected and that one of the higher-numbered buckets that contains the GDOT licenses is selected. For example:
Make notes of which license servers and, for each server, which buckets are selected. You will need to check this again after the installation.
Click βDoneβ on this dialog. If you made any changes then click βApply Changesβ on the βSLM Configuration Wizardβ dialog.
Next, in the βSLM Configuration Wizardβ dialog, expand the βAdvanced Settingsβ list of options. The key step here is to make sure that βEnable Broadcastingβ is unchecked (deactivated). If it is checked then uncheck it and again click βApply Changesβ:
Close the dialog.
If you made any changes to the license configuration then reboot your machine at this point.
If there is a GDOT Emergency Patch (EP) or Field Test (FT) installed, you must first uninstall it. This rolls the installation back to the state of either the main release (e.g., V11) or the main release plus previous CP (e.g., V11 CP1). Next run the installer for the new CP. For example, starting with V11 CP1 EP6:
Uninstall EP6 to roll back to V11 CP1
Next run the installer for CP2 (without first uninstalling V11 CP1)
The state of the GDOT install is now V11 CP2 (we successfully installed CP2 on top of V11 CP1)
Make sure you reboot the machine each time you are prompted to do so. Do not wait to reboot later. In particular, do not apply additional patches without first rebooting.
Use the AspenTechn SLM License Manager to check that:
The servers configured before the install are still configured after the install.
For each license server only the expected buckets are selected (i.e., match the configuration you noted before the install).
The βEnable broadcastβ setting is unchecked.
If you need to make any changes then make sure you reboot the machine afterwards.

Problem Statement: Minimum Alert Duration (MAD) is ignored for agents getting data from a CSV historian, alerts are sent out immediately the probability threshold is exceeded. | Solution: The MAD may look like it's being ignored if the Interpolation Mode for the CSV historian is set to None. This is because when the Interpolation Mode is None data points coming into Aspen Mtell may not be evenly spaced out, which can lead to multiple data points in each granule of time (for example, two data points falling within one hour in a data set with hourly granularity).
To resolve this, follow the steps below to change the Interpolation Mode.
1. Log into Aspen Mtell System Manager and click on Configuration > Settings > Sensor Data Sources
2. Select your CSV historian from among your sensor data sources
3. In the Configuration section check to see what Interpolation Mode is selected. If it is currently set to None select either Linear or Stair Step. If unsure of which to select then select Stair Step. Click Save

Problem Statement: When trying to pull long periods of data using the Historical Values in the Excel Add-in on Microsoft Excel 2013, the user gets #VALUE! in the cells the data was supposed to be showed, although receives a βSuccessβ message (see image below). This document explains why this happens and how to overcome this issue. | Solution: This happens because Microsoft Office 2013 has limitation of 65536 rows for array formula. So, for instance, if the user systemβs pulls data in a tag for every 1 minute, that means 65536 rows can hold up to around 45 days of data, thus Excel shows the error #VALUE! when that limit is reached.
In order to avoid that, there are two options:
The user can either upgrade to a more recent version of Microsoft Office (the 2016 version, has increased the limit to more than 1 million rows) or
Uncheck Output results as an array in the Advanced⦠option that appears on the Excel Add-in right left menu. This way, the output can be the same as Excel worksheet's max size and the user can still use his/her same Office version. To uncheck that, these are the instructions:
After clicking on Historical Values in the Aspen Process Data tab, a menu will show up on your right side of the screen. Click on Advancedβ¦:
Uncheck the box that says Output results as an away and then click on OK:
Close Excel, reopen it and pull the data using Historical Values again.

Problem Statement: Example to achieve the Pure Sulfur separation from the mixture of CS2, H2S, SO2 mixture. | Solution: This application is part of the sulfur process, where column could be used to separate sulfur from the mixture of CS2, H2S, SO2 mixture.
In the attached example, model is for the liquid sulfur as a single component βsulfurβ. Based on saturated vapor pressure for the apparent sulfur component.
Aspen Plus data regression tool is utilized to fit PLXANT (Extended Antoine vapor pressure equation) to match this data with extremely close agreement to the data in the released articles.
Solubility of sulfur in CS2, H2S, and SO2 is referenced as the data for solubility of sulfur in CS2 to fit the Gibbs energy of solid sulfur.
H2S solubility in liquid sulfur in the NIST database was available & applied with some modifications based on the experience to fit the Henry law coefficient for H2S in Sulfur.
Assumptions made:
Henry binary parameters for H2S/Methane was not available, copied Henry binary parameters pair from H2S/Pentane to avoid missing property parameter error.
Henry binary parameters for N2/Sulfur was not available, copied Henry binary parameters pair from N2/C2S. This parameter controls the apparent solubility of nitrogen in liquid sulfur.
Above parameters could be regressed using experimental or literatures data but for this specific example assumptions are made as above.
It is assumed that the solubility of elemental sulfur in water is extremely low, this is controlled by the NRTL binary parameter for water/sulfur pair. For convenience, user can assume:
Tij = Aij + Bij
Let Aij = 0
Let Bij = Bji
Attached model has Bij = 750. user can change this from the property environment if user wants to force lower water content.

Problem Statement: Why can I not open an APS Access Database model even if I have installed a version of Microsoft Access? APS uses OLE DB technology to read and write a model in Access Database with file extension .mdb or .accdb. The OLE DB component is installed with a Microsoft Access Database Engine (called Microsoft Access 2013 Runtime for Office 2013). Note that you may still be able to open an Access Database model with an ODBC dsn file without OLE DB.
You may encounter an error when attempting to open an Access database even though you previously installed the Microsoft Access Database Engine and could open the model. A Microsoft update may corrupt the registry values for an existing Access Database Engines, causing the inability to open an existing Access database model. | Solution: We recommend you:
Un-install the Microsoft Access Database Engine.
Download and install the 32bit version of Microsoft Access 2013 Runtime from Microsoft.com. Because APS is a 32bit application, you should download the 32bit version no matter if your machine has 32bit or 64bit Office.
You should be able to open you model after installing the Access 2013 Runtime from the following location:
https://www.microsoft.com/en-us/download/details.aspx?id=39358
If you install Access Database Engine 2016
If you install Access Database Engine 2016 instead of Microsoft Access 2013 Runtime, you may see a message similar to the following:
βOffice 16 Click-to-Run Extensibility Component 64-bit Registration prevents Office 365 32-bit installationβ.
Use the following steps to uninstall the 64bit Office 16 Click-to-Run Extensibility Component:

Problem Statement: The V7.3 package of DVDs could contain as many as three (3) DVDs with DVD 2 as part of their label.
The three DVDs would be labeled as DVD 2T, DVD 2 (32-bit) and DVD 2 (64-bit)
Which one should be used to upgrade (or newly install) Aspen Role-Based-Visualization (RBV) | Solution: Aspen Role-Based-Visualization (RBV) actually exists on all three DVDs for different situations.
DVD 2T is the one to be used if using the all-inclusive token-based licensing model that was introduced in July 2009. It can only be used with token based run-time license keys. See our article 129084 for more details on how to see if you have token licenses. If not using token-based licensing then the choice between the 32-bit and 64-bit DVDs depends on the Operating System(O.S.) of the PC. If upgrading from a version earlier than V7.3, on the same PC, then the only choice is to use the 32-bit DVD. This is because this product was not supported on a 64-bit system until V7.3 If newly installing on a 32-bit O.S. then again the 32-bit DVD would be used. However, if newly installing (via an upgrade or not) on a 64-bit O.S. then the 64-bit DVD should be used. Remember also that the version of Microsoft Sharepoint is also dependent on the Operating System.

Problem Statement: This Knowledge Base article provides steps to resolve the following MMDM Validation errors:
Item (...) referenced by property BPCIdentifier of item (.....) could not be found
which may be encountered in the Publish Form when generic items are deleted in the Aspen Manufacturing Master Data Manager database without cleaning up the references first. | Solution: At the present time, mMDM does not provide built-in referential integrity. It is left up to the user to manage dependencies between various definitions. To resolve this situation, currently there is only oneSolution, which is for the user to undelete the definitions that are causing the orphaned references.
The trick is finding the item to undelete. Here are some guidelines:
If you see bracketed numeric references, such as {100000, 1, 100018}, from this you can decipher the definition type. Use the table below to determine which component and collection the item belongs to. In some cases the error message will provide clues, such as AliasDefinition with ID: '100010'.
Keywords:
References: d DomainNamespace with ID '100005' not found. This message informs you that the missing item is a DomainNamespace (aka. Alias Domain), which is found under the Alias folder in the mMDM Editor.
Once you have identified the component and collection, you must undelete the item, as follows:
1. Use the mMDM Editor to navigate to the folder that contains the collection.
2. After selecting the collection folder, select the View | Filter menu.
3. From the Filter window, enable the Show only deleted definitions checkbox.
4. Close the informational dialog box, if it appears.
5. Now you should see a list of past deleted items in the grid. You can right-click on the item, then select Undelete.
6. This will show the Lifespan Editor window, which allows you to configure the desired end time for the item. For most cases, you should accept the default end time, so simply click OK.
7. The item is now undeleted, and will disappear from the deleted list. To return to the normal grid list, either use the Filter window to uncheck the Show only delete definitions checkbox, or simply right-click in the grid to show the context menu, then select Clear Filter. (Note: simply selecting a different collection will also automatically clear the filter.)
8. Once all of the orphaned references have been undeleted, you should then remove any references to them held by other items. For example, regarding aliases, you should use the Alias editor to remove any alias entries that refer to the item. If you plan to delete a Domain Namespace, then you should ensure that there are no aliases defined for that namespace in the Alias Editor.
9. After all references have been removed, then you can go back and safely delete the items again that we had just undeleted, since they no longer will result in orphaned references.

Problem Statement: mMDM (formerly known as ODM) provides several config files under \AspenTech\Enterprise\CDM\Configuration. Some have extensions of ?.config? and others have ?.adoconfig?. Those ending with ?.config? are known as workspace configuration files. A workspace describes to mMDM how to connect to a specific data source and which components an application should dynamically load at runtime. The ?.adoconfig? files contain database connection settings to a live relational database (which is ignored if no database is setup for the computer). | Solution: Here is a description of each of the workspace files used by Aspen Manufacturing Master Data Manager :
File Name
Description
Used By
Default_Database
A default workspace for connecting to a live database connection. It obtains the DB connection info via a reference to BPC_Default_SQL.adoconfig.
mMDM Editor
mMDM Bulk Load
mMDM Administrator
Any other client application configured to use this option as configured in the mMDM Administrator via the Data Source Wizard.
mMDM Service (Windows background service)
Default_Files
A default workspace for connecting to read-only XML files that have been published to the computer.
mMDM Editor
mMDM Bulk Load
mMDM Administrator
Any other client application configured to use this option as configured in the mMDM Administrator via the Data Source Wizard.
Default_WebService
A default workspace for connecting to a live database connection. Instead of using the file BPC_Default_SQL.adoconfig, it obtains the DB connection info via a call to an mMDM Web Service on the master mMDM server.
mMDM Editor
mMDM Bulk Load
mMDM Administrator
Any other client application configured to use this option as configured in the mMDM Administrator via the Data Source Wizard.
BPCWebAdmin
A special workspace for connecting to a live database connection. It obtains the DB connection info via a reference to BPC_Default_SQL.adoconfig. This workspace is identical to Default_Database, but is provided separately in case a site wants to customize it for web applications.
mMDM Web Manager
mMDM Web Service
OpsNav
Published
A special ?hybrid? workspace for connecting to both a live database connection and read-only XML files. It obtains the DB connection info via a reference to BPC_Default_SQL.adoconfig. Some components get their data from the database, while others are configured to get data from the XML files.
OpsNav
BPCSubscribe
A special ?hybrid? workspace for connecting to both a live database connection and read-only XML files. It obtains the DB connection info via a reference to BPC_Default_SQL.adoconfig. Some components get their data from the database, while others are configured to get data from the XML files.
mMDM Service (Windows background service) for the purposes of subscribing to published XML files.
The Default_WebService.config file is NOT used to configure the mMDM Web Service. Instead, that config file is intended for mMDM client computers that wish to obtain the database connection settings from the mMDM Web Service running on the mMDM master server. By default, the mMDM Web Service uses BPCWebAdmin.config, which is the same workspace configuration file used by the mMDM web site.
You can change the workspace used by the mMDM Web Service by changing the value for ?WORKSPACE_ALIAS_NAME? in the <appSettings> section of the Web.config file in folder ?\Program Files (x86)\AspenTech\mMDMWebServices_V7.3?. It defaults to BPCWebAdmin, but you could change it to ?Default_File?, for example, to cause the web service to use the read-only XML files. And then perform an IISRESET. This configuration has never been tested, and it will probably fail because the web service will expect a writable workspace.

Problem Statement: This Knowledge Base article provides steps to troubleshoot SmartClient startup and update issues. | Solution: The Smart Client is a mechanism that allows the mMDM Advanced Editor to be accessed from the mMDM (Web) Manager (mMDM?s web user interface).
There are two ways to launch the mMDM Editor. One is via the Smart Client on the mMDM Web Manager. Alternatively, if you are on a computer where mMDM has been directly installed, such as an mMDM Server, you can launch the Editor from the Start menu, directly.
If that still fails, then please search for the assembly named Interop.aspenSecurity in the Global Assemby Cache (GAC) found under c:\Windows\Assembly folder. If not found, then it means that AFW Security is not fully installed. Modify the AFW Security install and be sure to select the feature named ?AFW Security .NET Components?. If the assembly is found, then please right-click to view the Properties, then from the Version tab, confirm that the version is 4.0.0.509.
And last but not least, please deactivate the IE Enhanced Security module which by default is set to Active.
If the above steps do not resolve the issue, try to update the SmartClient on the mMDM server by following the steps below.
The Smart Client can be updated on the computer where the mMDM Manager is located. To update the Smart Client, please perform the following steps:
1. Launch the Smart Client update utility named SetupSC.exe which is found in C:\Program Files\AspenTech\mmDMWebManager_V7.3\SmartClient folder.
2. Press the Update Smart Client button.
3. Press the Close button (X) in the upper right to exit the utility.
4. A new folder will be generated using the naming convention of ?AdvancedEditor_7_3_0_3000?.
5. The SmartClient should now be properly configured.
Due to the wide variety of deployment scenarios (OS versions, certificate issues, etc), unforeseen issues could arise when using SetupSC.exe to update the mMDM smart client configuration. For example, SetupSC.exe uses Microsoft?s certificate capabilities to ?sign? the smart client packages so that they can later be safely downloaded from the mMDM Configuration (Web) Manager to other user computers. Sometimes the signing process can have problems. The SetupSC.exe has some new features, such as logging, which should help to diagnose these kinds of problems.

Problem Statement: The ad hoc Aspen Production Record Manager (Formerly Aspen Batch.21) reports can fail with the following error message when run from the Batch Query Tool or Batch Detail Display:
Cannot find 'C:\Program Files\AspenTech\Working Folders\\Batch.21\temporary report.htm'. Make sure the path or internet address is correct.
(Note: For the correct path to be found there should only be 1 slash before the word 'Batch.21' in the path listed above.)
NB: This issue can also be seen when running Windows Server 2008, however the error message will be:
Cannot find 'c:\users\USERNAME\appdata\local\temp\3\Batch.21\temporaryreport.htm' | Solution: The Batch.21 executable appends \Batch.21\temporary report.htm to whatever it finds in the ASPENWORKINGDIRdir registry key. This registry key is located in:
HKLM | Software | AspenTech | Setup
Make sure the contents of this key do not end with a slash. Assuming your install path is on the C:\ drive, the contents of ASPENWORKINGDIRdir should look like this:
C:\Program Files\AspenTech\Working Folders
not like this:
C:\Program Files\AspenTech\Working Folders\
For Windows Server 2008:
1. Ensure you are running the Query tool with Run as administrator option (right click the program to access this option.)
2. Turn off User Access Control.

Problem Statement: This Knowledge Base article answers the following question:
Can MS SharePoint web parts access Aspen Operations Domain Model (ODM) data? | Solution: Data View Web Part is an MS SharePoint web part that can read from many data sources such as MS SQL Server, XML,.. and display data using XSLT. Aspen ODM exposes web service that allows external tools to access ODM data. Therefore, it is possible for the users to configure Data View Web Part to access ODM data thru the ODM Web Service.
In order to see the ODM Web Service's available methods, open your Internet browser and go to the following url:
http://localhost/BPCS95WebServices/BPCS95WebService.asmx
Example:
The GetDataValue method can returns the data value read using Equipment.Equipment.TK101@!Name
Below is a link to a website that shows the steps to configure the Data View Web Part to access web services.

Problem Statement: Is there versioning on the hierarchy / mMDM? Is rollback possible? If not, what is the point of versioning? | Solution: There is no versioning by Hierarchy β there is only versioning of the workspace or, more precisely, of the mMDM database where all your hierarchies live. What this means is that every time you make changes to your hierarchy and publish it, a new version of the mMDM database is created containing the changes. It is therefore possible to connect (not rollback) to a previous (or older) version of the database and your older version of the hierarchy. Below is a screen capture showing how itβs done.
Again, this is not the same as rollback because, at this time you cannot edit a past published version. Publishing a new version effectively takes a snapshot of the data and freezes it, becoming immutable. To edit data, you must change back to the working version.
The intent of versioning is to create an official, approved snapshot of the data that can be published out to other computers. Other applications can then generate XML documents (such as BPDs) with the version ID embedded. Later that XML document can be properly processed by referencing the originally published mMDM version, such as when resolving aliased names. So versioning is intended for cases where reference data might get used in an XML message and that message is processed at a future time.
To resolved data corruption issues, you should rely on the database backup tools from the RDBMS vendor, since versioning is not designed as a backup/restore mechanism.
Currently, there is an enhancement request in place to allow a past version to be promoted to the working version. The enhancement, if approved, will be implemented in a future version of mMDM.

Problem Statement: How do I add an mMDM hierarchy to another mMDM hierarchy? | Solution: Let us suppose that we have two hierarchies that we want to join together to make maintenance simpler or to add additional content to one of them.
In our example we will join a hierarchy called Material with a hierarchy called S95.
1. Open each hierarchy and in its Hierarchy Definition Settings set the IsContentMixed property to True
2. Next, navigate to the Hierarchies folder in the hierarchy that you want to add an additional hierarchy to (S95 in our example) and drag that hierarchy (Material in our example) to the Design pane over the top node in our base hierarchy (S95).
3. Select No when presented with the following dialog box to add the selected Hierarchy Definition as a Hierarchy
Keywords: None
References: node:
4. The Material hierarchy has been added to the S95 hierarchy:
5. Save and publish your hierarchy.
6. View your hierarchy in Aspen Operations Navigator. |
Problem Statement: How to resolve the error S95 can't be connected. BPC S95 Web Service is not responding: http://<servername>/bpcs95webservicesanonymous/bpcs95webservice.asmx when trying to use S95 Search feature within Aspen Tag Browser. | Solution: Put the following URL in an Internet Explorer session:
http://<servername>/bpcs95webservicesanonymous/bpcs95webservice.asmx
Verify the following web page displays.
Scroll down to InitializeSession option.
Select the Invoke button.
If a similar error to the following appears, make the necessary changes and test again. In this instance, since SQL Server and mMDM are on the same machine the NT Authority\IUSR account needs to be added to SQL Server.
However, if SQL Server and mMDM are on separate machines then the NT Authority\Anonymous Logon account is required to be added to SQL Server.

Problem Statement: How to create a nested class item within another class in Aspen Manufacturing Master Data Manager. | Solution: The base class is created as an ordinary class, by right-clicking on the Classes folder and selecting New.
ClassA has been configured as the following:
Now create a ClassB to reference base ClassA where we set ClassA to be an array within ClassB. Note that you need to use the Data Types tab to add basic class data types. When adding another class to the design you must select the Classes tab that is currently selected in the image below. As you can see, ClassA has already been added to ClassB and the icon of ClassA denotes it is a nested class.
After adding ClassA to ClassB, you will need to change the IsArray field under Data Types to True.
Now an item that references ClassB will inherently reference ClassA as well.

Problem Statement: This knowledge base article explains the reason for not being able to edit or publish from an older version of a Workspace. | Solution: To fully understand the reasons why it is not possible to publish from an older version of a Workspace, let us first understand mMDMβs versioning concept.
When mMDM is first used, all changes are made to a βWorkingβ version. In fact, this is the only version that is writeable. At some point, the edits to the data model stabilize and it becomes ready for external consumption and distribution. At this point, the user can elect to generate a βPublishedβ version. The purpose is to create an official immutable version (snapshot) of the master data model. Since this snapshot is immutable, it serves as a certification of the data within. The published version is then able to be freely pushed to client-side systems to reference the sanctioned data. Client-side mMDM applications have the option of using a direct database connection to the published version, or receiving a copy in XML form via the EIF pub/sub feature.
The mMDM Publish feature was not intended as a backup/restore mechanism.
To be able to go back to an older, published version of a Workspace, I recommend creating a backup copy of the mMDM database using the database backup tools from the RDBMS vendor, every time you publish a new version of the Workspace.

Problem Statement: After adding items to a hierarchy in Aspen Manufacturing Master Data Manager the following Validation Errors window appears:
Duplicate Identifiers found | Solution: The reason this window appears is because the individual hierarchy properties have been set to not allow more than one kind of item to be added.
This setting is initially set when creating a new hierarchy. In the screen capture below, be sure to select the Allow multiple instances option when creating a hierarchy.
If the hierarchy has already been created, you can change the setting in the lower left-hand corner of the mMDM Definition Editor for a specific hierarchy. Change the IsSingleInstance field to FALSE to allow more than one kind of item in a hierarchy.

Problem Statement: When trying to download the AtOdmEditor from the Aspen Operations Domain Model (ODM) Web Manager page a download error is generated. The error says the AtOdmEditor.exe.config file cannot be found. This is an ODM Smart Client download issue on Windows Server 2008 with IIS 7.0.
This Knowledge Base article shows how to properly configure the Internet Information Services (IIS) 7.0 to allow the AtOdmEditor smart client to download. | Solution: The reason we get the File not found error is because under Windows Server 2008, the IIS 7.0 has restrictions on transferring certain files for the Web server. The two files recognized as not found are the new files we added recently to ODM: AtOdmEditor.exe.config and AtOdmEditorOffline.exe.config.
To allow the IIS 7.0 Web server to be able to access the files, we have to go to the following directory, and modify the config file which IIS 7.0 uses globally:
C:\Windows\System32\inetsrv\config\ApplicationHost.config
In there, find where the <requestFiltering> tag is, and modify the <add fileExtension=.config allowed=false /> from false to true, as follows: <add fileExtension=.config allowed=true />

Problem Statement: Knowledge Base article 125366 shows how to view the Aspen Infoplus.21 ( IP.21) data in Aspen Web.21 through Aspen Operations Domain Model (ODM).
This KB article provides a description of an advanced, yet easy to implement, feature of the integration between the ODM/IP.21 and Web.21. | Solution: Web.21 graphics support the building of a template for simplifying the construction of multiple complex graphics that contain repeated entities like reactors, pumps, motors etc. The templates work by specifying one or more replaceable parameters that you can use in scripts and/or tag name. For example, let's consider a batch reactor. Here is what the template looks like:
All the data that will be depicted on this template will come from an item definition in the ODM that has a particular class associated with it. For example, here is the definition in Web.21 of one of the points above:
The %base% is the default replaceable parameter that is defined when you place an instance of this template on a graphic. You can see from the definition that this parameter is the name of the item in the ODM. The part to the right of the @ character is the class and class attribute that is being displayed.
This component is described in the ODM by the following class:
All the attributes with the small yellow square with the red dot as part of their icons are dynamic attributes. Their values will come from fields in IP.21. When you are defining a class that can apply to many items though, it would be very convenient to be able to infer the actual tag names for the various attributes via some naming convention that you can build into the class definition so that when you create an item you don' t have to specify the tags for all the attributes as this would be a very tedious and mistake prone process. So, at the class level you can specify the 'Default' values for these attributes (the tags from which the actual data will come) and these can use naming conventions or reference other data within the ODM. For example, the DefaultValue for the 'ProcessStep' attribute is:
{0,IP21,0,string,<tag><Name tok=\><![CDATA[BMS_UNIT_STATUS-\Name\ 1 IP_TREND_VALUE]]></Name><Attribute></Attribute><Source></Source><Map></Map><datatype>string</datatype></tag>}
Everything within the {} characters is basically the tag definition.
The first parameter, 0, is an internal placeholder for the ODM.
The second parameter IP21 is the name of the Dynamic Data Source in the ODM. The ODM supports any process data as data source as well as relational databases and BPC and BPD. The last 3 are beyond the scope of what we are attempting to describe here.
The third parameter, 0, is used for SQL Query data sources and is the ID of the SQL query.
The fourth parameter, string, is the type of data you are asking the ODM to return for this tag definition, valid values are also integer and double.
The fifth parameter is an xml definition of the tag. It needs an enclosing <tag> element.
The name sub element of the <tag> is the tag name. This is often specified in an XML CDATA section as in the above example. The name element also supports a 'tok' attribute. This is the character to use in the tag name to indicate special processing of a section of the tag name between tokens. The special processing is reflected access to the ODM. In the above example, the actual name of the item to which this class is applied will be substituted for the /Name/ section of the tag name. You can use the advanced viewer to determine other available properties.
There are some special things you can do in these sections as well. One of them is access other class attributes. The simplest way of accessing another class attribute is to use the key sequence @../ . @ is shortcut for the ClassValueFind method. For example,
{0,IP21,0,double,<tag><Name tok=\><![CDATA[\@../TemperatureTag\ IP_VALUE]]></Name><Attribute></Attribute><Source></Source><Map></Map><datatype>double</datatype></tag>}
In the above DefaultValue \@../TemperatureTag\ will be replaced with the contents of the TemperatureTag attribute in the same class definition as the attribute being defined. ../.. will look at attributes of the parent class etc.
One other special keyword is the ResolveIdentifier which will basically let you look at another ODM Item by appending it to an attribute that contains a pointer to another ODM identifier. You can, for example, get the name parameter by saying ResolveIdentifier.Name.
Dynamic class attributes (like any class attribute) can also be passed to calculations in the ODM just like any class attribute. The ODM will take care that the dynamic data is obtained before the calculation is called. Since the results of the calculations can be bound to a class attribute these can be directly used in Web.21 as well.
NOTE: Historical data reads using ODM Dynamic Data are not supported in the current (2006.5 and V7.1) releases of aspenONE. There's an enhancement request (CQ00335067) to make it work in a future release.
