Problem Statement: How to install Software License Manager (SLM) License Server? | Solution: This knowledge base article provides the installation steps for the SLM License Server application. AspenTech recommends to setup a seperate server (Physical, Virtual, or Cloud) to host SLM License Server. Please refer to the software and hardware specifications here.
First, download the latest version of the SLM Tools from the Download Center.
Once you have downloaded the SLM Tools, extract the zip file to a local folder on your C drive and then run setup.exe with the Run as Administrator option.
Next, follow these steps to install the SLM License Server:
1) At the Welcome screen, click the Install and configure SLM button.
2) Accept the aspenONE Software License Terms by checking the I accept the terms of this agreement checkbox and click Next.
3) At the aspenONE Product screen, expand SLM License Server and SLM Tools and select the following minimum requirements to be installed:
a. SLM License Server
i. Auto Upload Tool
Note: HTTP Server is optional. If this license server will also act as a usage log collection server, then this option will need to be installed.
b. SLM Tools
i. SLM Server Admin Tools (WLMAdmin for Administrators)
ii. SLM Client Tools
Note: Dongle Driver and Aspen Licensing Dashboard are optional. The Dongle Driver will need to be installed if your license is locked to an Aspen USB Dongle.
4) At the Specify license file screen, click on the Browse button and select your license. Click Next.
Note: The license will be loaded automatically after the install. You may choose not to load your license during the install, but you will need to load it manually after the install. See knowledge base article 22408 to learn how to load a network license.
5) At the Specify Window services account information screen, provide a domain account username and password that has administrative privileges. Click Next.
Note: If your computer is not on a domain, you can use the local Administrator account by typing the computer_name\Administrator in the username field and use the Administrator password.
You may also use the computer’s SYSTEM account by typing in ‘SYSTEM’ for the username and leave the password blank.
6) At the Verify your installation screen, click the Install Now button.
7) During the installation, around 91% completion of the SLM License Server, the Auto Upload Tool will display its Configuration Tool. You may close the window and configure this at a later date or configure it now and click OK.
Visit knowledge base article 22451 for more information about configuring the Auto Upload Tool.
Note: The installation will pause until an action is made. When the Configuration Tool is displayed, it may be hidden behind the installer.
8) Once the installation is finished, click the Finish button.

Problem Statement: Is it possible to connect the GDOT Offline applications to the plant operations OPC server using GDOT Simulation Console? | Solution: Yes, it is possible.
GDOT Offline is a subset of the capabilities of GDOT Online, nevertheless, GDOT Offline supports using OPC I/O tags and APC Gateway I/O tags.
The point of GDOT Offline is for project engineers to test the behavior of the GDOT applications online. It is expected that the OPC servers and APC servers would be test servers (e.g. in a customer's testing lab or training lab).
However, when GDOT Offline is installed on the online system, the OPC servers that can be reached are the same as for GDOT Online and GDOT Offline applications can connect to them if configured to do so.

Problem Statement: How to resolve the problem that Variables change in Excel is not displayed in Aspen Plus? | Solution: This can occur for one of two reasons:
If you put an equation in a cell, the equation will take priority over any attempt to enter a new value on the form in Aspen Plus.
Aspen Simulation Workbook expects you to change specified variables from Excel.
To fix, close the form/dialog box in Aspen Plus; then, open it back up; you will now see the value is consistent with Excel.
Another way to force an update, is to click the Refresh button in the Workbook group of the ASW ribbon .

Problem Statement: All orders changed to Initiated status post Aspen Production Execution Manager (APEM) database upgrade | Solution: Post APEM database upgrade (done via database wizard) and recompilation of orders, we see all the past orders migrated from old system to new system in Initiated status.
In the old flags.m2r_cfg config file the following key assignment is present “FINISH_ORDER_BY_PFC_FLOW = 0” but in the new one it is commented out. This explains the different status values for the orders.
Following key assignment in flags.m2r_cfg file should fix the problem (it’s already present but commented out, so just uncomment it and run codify_all).
FINISH_ORDER_BY_PFC_FLOW = 0
The key only impacts the way order status is calculated and displayed on the screen. It will not change anything for existing completed orders in the database. There is no need to execute CompileProc again.

Problem Statement: This best practices article summarizes the recommendations given in KB Article 129045-2 (Configuring History Repositories for Optimal Performance). | Solution: 1. Create a dedicated Aspen InfoPlus.21 history repository for each distinct data source (i.e., every CIMIO server, Aspen Calc, calculated values from queries or external tasks, etc) to avoid placing data in older archives when forwarding stored Aspen Cim-IO data.
2. Create enough repositories so that no single history repository handles more than ten thousand history repeat areas.
3. Configure the archive shift criteria ('File Sets Size' and 'Time Span') so that archive shift will not occur more than once a week for a given history repository. Increase the file-set size to the desired maximum archive size (typically 1000 MB or more).
4. Set the 'Cache Buckets' specified on the Repository tab of the Properties dialog of the Aspen InfoPlus.21 Administrator to be greater than the number of history repeat areas assigned to the history repository.
5. Increase the history event queue 'Buffer Size' in the Advanced tab of the Properties dialog of the selected history repository to at least 1000000 (1 million bytes) on Aspen InfoPlus.21 systems that must handle large surges of process data to be archived (i.e. five thousand points per second or where Aspen Cim-IO store-and-forward is enabled).
6. AspenTech recommends placing file-sets on local drives. SAN devices with dedicated high-speed fiber-optic cables may also be used. Do not use network drives or NAS devices.

Problem Statement: What is the name convention for the AORA reports? | Solution: All of the report filenames follow a specific naming convention, and this naming convention allows you to quickly determine the basic format for the report from the file name. The naming convention follows the following format: abbccddeef.rpt (The import table views have the same names as the corresponding import tables).
The first character describes the type of report: daily, monthly, graphical, custom, or other miscellaneous type of report. The first character of the report will be one of the following characters:
Character Description
d Daily Report
m Monthly Report
g Graphical Report
c Custom User Report
i Import Report
o Other Miscellaneous Report
v View Report
The next characters are grouped in pairs and any report may have as many as three pairs to further describe the report. These pairs will be one of the following character pairs:
Character Description
bl Balance
cp Components
cv Cover page
cy Charge and Yields
ev Event
in Instrument
mt Meter
nt Notes
pd Product
pi Pipe
pr Properties
rf Refinery
sr Sales and Receipts
tk Tank
tr Transfer
vs Vessels
The last character in the file name indicates whether the report is using the measurement of volume or mass, or it describes the presentation of the report as detailed, landscape, or portrait. The last character of the report will be one of the following characters:
Character Description
v Volume
m Mass
d Detailed
l Landscape
p Portrait
Example: The dsrpdd.rpt report will serve as an example, simply break down the name as follows:
The first character 'd' means it will be a daily report.
The second and third characters form the pair 'sr' which means it is a sales and receipt report.
The fourth and fifth characters form the pair 'pd' which means it has product information in it.
The last character 'd' means that it is a detailed report.
When all of this is combined together, it results in a daily sales and receipt product details report.

Problem Statement: Query example to move Transfer Records from one Logical Device to another. | Solution: The steps required to move a Transfer Record to another Logical Device are the following:
Turn OFF the Transfer Record.
Set the Transfer Record to Unusable.
Change the IO_MAIN_TASK to the corresponding in the second Logical Device.
Set the Transfer Record to Usable.
Turn On the Transfer Record.
In order to do it for all Transfer Records that share the same Definition Record, the following query can be used:
UPDATE IOGETDEF SET IO_RECORD_PROCESSING = 'OFF' WHERE IO_MAIN_TASK = 'TSK_M_1';
UPDATE IOGETDEF SET USABLE = 0 WHERE IO_MAIN_TASK = 'TSK_M_1';
UPDATE IOGETDEF SET IO_MAIN_TASK = 'TSK_M_2' WHERE IO_MAIN_TASK = 'TSK_M_1';
UPDATE IOGETDEF SET USABLE = 1 WHERE IO_MAIN_TASK = 'TSK_M_2';
UPDATE IOGETDEF SET IO_RECORD_PROCESSING = 'ON' WHERE IO_MAIN_TASK = 'TSK_M_2';
Where TSK_M_1 belongs to the Source Logical Device and TSK_M_2 to the Receiving Logical Device.
Note: This example query will work for the Transfer Records defined under IOGETDEF. If it is desired to use it for another Definition Record, it is required to change that part of the query.
Example:
The Get Records Example 1 and Example 2 are within the Logical Device CIOOPC21 and it is required to move them to the Logical Device CIMIO_2
The group of Transfer Records share the same IO_MAIN_TASK.
Note: If after the initial configuration nothing is changed, the name structure for the TSK's is the following: TSK_M_XXXX, TSK_A_XXXX and TSK_U_XXXX, where XXXX is the name of the Logical Device.
IO_MAIN_TASK for the Source Logical Device:
IO_MAIN_TASK for the Receiving Logical Device:
Therefore the query will be the following:
UPDATE IOGETDEF SET IO_RECORD_PROCESSING = 'OFF' WHERE IO_MAIN_TASK = 'TSK_M_CIOOPC21';
UPDATE IOGETDEF SET USABLE = 0 WHERE IO_MAIN_TASK = 'TSK_M_CIOOPC21';
UPDATE IOGETDEF SET IO_MAIN_TASK = 'TSK_M_CIMIO_2' WHERE IO_MAIN_TASK = 'TSK_M_CIOOPC21';
UPDATE IOGETDEF SET USABLE = 1 WHERE IO_MAIN_TASK = 'TSK_M_CIMIO_2';
UPDATE IOGETDEF SET IO_RECORD_PROCESSING = 'ON' WHERE IO_MAIN_TASK = 'TSK_M_CIMIO_2';
After running the query the result is:

Problem Statement: How to determine the Maximum Number of Components in a Principal Component Analysis? | Solution: The exact total number of components is not important for most methods including Principal Component Analysis (PCA); For this method it is important that you have enough components to explain the main variability in the data. Once the noise starts to be present on your results, then is an indicative of non-important components, and that your model is adequately described with the previous X number of components used.
The most important thing when deciding on the optimal number of components to use in your final model is to use a proper validation. This can be either a separate test set or a cross-validation where all replicates are kept out in same segments
Note: All components from 1 to the optimal selected (validated) number can and should be interpreted to understand the underlying variability being explained by model.

Problem Statement: Where can I find Sustainability sample cases in Aspen HYSYS V12.1? | Solution: Aspen HYSYS V12.1 includes five new sample files to facilitate this objective. The new sample cases can be found by clicking the Examples button on the Resources ribbon and navigating to the Sustainability folder or by navigating to the examples folder (C:\Program Files\AspenTech\Aspen HYSYS V12.1\Samples\Sustainability). A PDF file is included with each example to illustrate the process.
Each of the following five carbon capture models demonstrates how carbon is captured from different sources of flue gases using Acid Gas fluid package in Aspen HYSYS. It is a typical two-column process. CO2 is absorbed by using solvent in the absorber and then regenerated in the stripper. The acid gas distillation columns are used to model the absorber and stripper. The column geometries and internals are identified, and the rate-based distillation column in Advanced Modeling mode is used for accurate prediction of the mass transfer in absorption and desorption. Finally, the utility feature is used in the example for a quick estimate of operating cost.
CO2 Capture from Coal Power Plant using MEA
This Aspen HYSYS example models CO2 capture from a coal power plant flue gas at the rate of 1 Million TPY by using MEA.
CO2 Capture from Natural Gas Power Plant using MEA
This Aspen HYSYS example models CO2 capture from a natural gas power plant flue gas at the rate of 1 Million TPY by using MEA.

This Aspen HYSYS example models CO2 capture from syngas for the IGCC process at the rate of 1 Million TPY by using DEPG.
CO2 capture from Syngas for IGCC using MEA
This Aspen HYSYS example models CO2 pre-combustion capture of the IGCC process at the rate of 1 Million TPY by using MEA.
Carbon Capture and Storage
This Aspen HYSYS example elaborates how carbon can be captured at the rate of 500,000 TPY from the exhaust gases coming from gas turbines, boilers and other sources using MEA. This model includes the modeling of sources, pre-treatment of flue gases, carbon capture, post-treatment and storage. The flue gases coming from different sources are at high temperature and must be cooled before they are sent for carbon capture. Water is knocked out in knockout drums, and O2 is removed using O2 removal units. The carbon capture is performed using a two-column process using Acid Gas package in HYSYS. The rate-based distillation column is modeled in efficiency modeling mode for accurate prediction of the mass transfer in absorption and desorption. After the carbon dioxide is captured, the pressure of the gases is increased before they are sent for injection into geological storage sites or for EOR in oil fields. That is done by using compressors and other pressure increasing equipment. Full description of the model can be found in the PDF provided with the model.

Problem Statement: The problem is related to Version V12.1. The problem basically occurs when you create a DMC3 project on the server or network location that is going to be modified by different users. In this case, take for example User A who is the owner of the DMC3proj. file and is saved on location X. If User B access location X and try to open the project (even if the project was properly closed and User A is logged out) DMC3 builder return with a message Project Is Already open like the picture below: | Solution: TheSolution to this problem is related to the user permission to the location folder, subfolders, and files. basically, theSolution is to create projects in public folders that multiple users have read/write permissions in.
If one of the users only has Read access the message will pop up and won’t allow the user to open the project. In the next example, the user gundam has only Read access thus the message pop up when trying to open the project.
In the second case, the user gundam has read/write access which allows to access the project.
In Both Cases, the user Student was the owner of and creator of the project.

Problem Statement: By Default, is not possible to Historize Controller User entries from the DMCplus or DMC3 Controller. However, this | Solution: presents a Workaround Using the capabilities of the IP21 Database to get a User Entry Historized.
Solution
The Following example was using an Example DMCplus controller named DEMCOL12, the following procedure is just to show the steps that must be done to have a User Entry historized and the Variables used in this example does not represent a real application:
1.- The first step is to create Two Different User entries on the Controller, in this case, we have created the Variables, TEST_ENTRY and WRITE_BACK:
It can be noticed that the variable TEST_ENTRY has been configured as Read, (but the variable can be configured as any other IO Flag). TEST_ENTRY will READ the values from the Measurement of an MV named SSFLOW which belong to the same Controller but will be displayed as one of the Parameters of the CV variable SSCOMP. The logic behind this is just to verify that the User Entry is getting the READ values from a dynamic source that will be changing with time (In a normal case this will come from the DCS).
On the other hand, WRITE_BACK is configuring as AWRITE as we will use this variable to Always Write the value back to the IP21 Database. In this case, we are pointing to a Created tag on the IP21 Database named WRBACK (we will back to this tag later).
2.- As the User Entries can only use one IO Flag at the time, we will use an input calculation to send the Reading Values from TEST_ENTRY to WRITE_BACK, then WRITE_BACK will Write the Values to IP21.
The Calculation is just the Following:
WRITE_BACK = TEST_ENTRY
3.- Once Step 2 is complete we will check now on the IP21 Database. In this case, I have Created an Analog Defined Tag name WRBACK ( In this particular case I just Duplicated an Analog Tag Pre-defined on my IP21 Database and Save it Under a Folder named USER_ENTRIES that I have created for this example)
As you can see in the first Picture the User Entry WRITE_BACK is pointing to the IO “WRBACK IP_INPUT_VALUE”. This is done because I want that the Written value from WRITE_BACK ended up been Writing in this specific Field so every time WRITE_BACK sends values, they will be written on the field IP_INPUT_VALUE (which I can later on Plot on Process Explorer or bring the Values using Aspen SQL).
Take into account that the correct configuration to Historize values is to set the filed for IP_REPOSITORY, IP_ARCHIVING AND IP_#_OF_TREND_VALUES.
4.- Once all is correctly Configure the next step, will be to deploy the Controller and Start the Collection in AW. I have run a few tests to show the Historization of the User Entry in the AW IP21 Database.

Problem Statement: How to modify the fixed area of a record by importing data from a .CSV file? | Solution: This query helps you to modify the fixed area of a record by a template in a .CSV file.
First you have to create a .CSV in Excel with this structure:
<Tag Name> <Field 1> <Field 2> .... <Field n>
For this example, the description, engineering units, High high limit, high limit, low limit and low low limit fields will be modified:
Then in the query the columns of the .CSV file must be defined as local variables and in the for loop enter the name of the .CSV file and its path.
local nameoftag InfoPlus.21 Data Type;
local Field1 InfoPlus.21 Data Type;
.........
local Fieldn InfoPlus.21 Data Type;
for (select line as tagname from '.CSV path and name' where linenum > 1) do;
nameoftag = substring (1 of tagname between ',');
Field1 = substring (2 of tagname between ',');
......
Fieldn = substring (n+1 of tagname between ',');
Update IP_analogdef
set Field of record fixed area = Field1, ..... Field of record fixed area 2 = Fieldn where name = nameoftag;
end;
For this example the code would be this:
local description char(25);
local nameoftag char(25);
local engunit char(10);
local highhigh real;
local high real;
local low real;
local lowlow real;
for (select line as tagname from 'C:\Users\Student\Desktop\test.csv' where linenum > 1) do;

Problem Statement: When you redeploy an RTE controller in V12.1, the Master Request and Status go to OFF without giving any warning or message when using the Warm Initialization option. | Solution: For previous versions, DMC3 Builder shows up a warning message saying that the controller must be turned OFF before redeploying when using the Warm Initialization option.
In V12.1 you can redeploy with the MasterOnOffStatus ON, but you need to have an IO tag linked with the MasterOnOffRequest.
In V14.0 the defect fix removes the requirement of having an I/O tag as a work-around for keeping the controller with the MasterOnOffRequest ON.
Fixed
In V14.0.

Problem Statement: The Merge action allows joining two or more DMC3 applications in one application. This action keeps the applications Models, Cases, and Configurations from the previous application on the new one. However, there are a few tips to remember when you need to perform this action. | Solution: 1.- Import the application into one project that considers the main application. Also, do not affect this main application consider having a backup copy of this project.
2.- Check the list of options that you consider correct for the application. By default, the merge controllers window will allow you to Merge Models, Merge Tuning values, Calculation and User Define Entries and Marge identification Cases. If one of these is not needed, consider unchecking the boxes. This helps just to keep the information you need for the new merged application.
3.- Consider the following case. Application A has a model and a basic Configuration and Application B is a more advanced application that has a Model, a robust configuration, and Optimization Values. In this case, you need to conserve the configuration and tuning of B application. When you click on Merge the Merge Controller window will appear and it will ask you to select a primary Controller and a Secondary Controller. In this case, as it needs to priority to conserve the parameter for Application B, this one needs to be set as the secondary controller and set A as the primary controller. Otherwise, the configuration of application A will be set as a priority and the configuration of Controller B will be lost in the new merged application.
4.- The Merge Action only allows merging two applications at the same time. If you require to have more than two applications, then you will need to merge the product of the first merge process with the next application. Let say that you will need to merge A, B and C. Then you need to merge first A and B, and then the AB application needs to be merged with C. (Note: Keep in mind the previous consideration for this last actions)

Problem Statement: How can the equilibrium of a reaction be controlled/specified in a RGibbs reactor? How do you restrict the equilibrium in the simulation?
What is the temperature approach option in the equilibrium reaction, and how can it be used to modify the effluent composition from an equilibrium reactor?
This option is useful in modelling applications such as fired-reactor reforming furnaces with low-activity catalyst. | Solution: In RGibbs, you can restrict the chemical equilibrium with two Calculation options on the Setup | Specifications sheet: Restrict chemical equilibrium - specify temperature approach or reaction extents or Restrict chemical equilibrium - specify duty and temperature, and calculate temperature approach
If you select Restrict chemical equilibrium - specify temperature approach or reaction extents, you must specify one of these two options on the Setup | Restricted Equilibrium sheet:
Temperature approach for the entire system to select the Entire System With Temperature Approach option, and specify the temperature difference between the chemical equilibrium and reactor temperatures. Use a negative value if the reactor temperature is greater than the temperature at which RGibbs calculates chemical equilibrium.
Temperature approach or molecular extent for individual reactions.
The equilibrium can be restricted in the following ways:
Specifying the molar extent of the reaction (EXTENT-SPEC) for any individual reaction defined by a STOIC statement. This should not be entered for a reaction that has a temperature approach specified by a TAPP-SPEC statement.
Set the temperature approach to chemical equilibrium for any of the individual reactions defined by the STOIC statement. A temperature approach (TAPP-SPEC) should not be entered for a reaction that has an extent fixed by an EXTENT-SPEC statement.
Select the Individual Reactions Option, when you want to restrict one or more chemical reactions from reaching chemical equilibrium by specifying a reaction extent or temperature approach. To specify new reactions, click the New button and specify the stoichiometry and equilibrium restriction in the Edit Stoichiometry dialog box. After specifying one or more reactions, you can use the Edit button to modify and the Delete button to remove existing reactions.
Note 1: If either molar extent or temperature approach is specified, then the stoichiometry for a set of linearly independent reactions involving all components present in the system must be specified. Only these reactions are used. In addition, the set of reactions needs to be complete and satisfies the degrees of freedom of the system. In REquil, you can have a partial set of reactions.
Note 2: If you do not specify molar extent or temperature approach (that is, all reactions are set to the default 0 temperature approach) then RGibbs ignores the reactions. In this case, no restrictions are enforced on the reactions specified.
If you select Restrict chemical equilibrium - specify duty and temperature, and calculate temperature approach, both temperature and heat duty must be specified. RGibbs calculates the temperature approach to chemical equilibrium internally. You can provide an estimate of the temperature approach on the Advanced | Estimates sheet and energy balance convergence parameters on the Advanced | Convergence sheet. The default value for temperature approach estimate is 0.
When Restrict chemical equilibrium - specify duty and temperature, and calculate temperature approach is specified, the chemical equilibrium constant is evaluated at the temperature T + DeltaT, where T is the actual reactor temperature specified by the user and DeltaT is the desired temperature approach. If a temperature approach for the entire is desired, the Restrict chemical equilibrium - specify temperature approach or reaction extents option should be used instead. For this case, the chemical equilibrium is computed at T + DeltaT, while the phase equilibrium is computed at T.
Temperature Approach
The temperature approach option in the equilibrium reaction allows the user to adjust the equilibrium constant of a reaction by offsetting the temperature at which it is calculated. The approach value is an empirical adjustment that is used to modify the extent of reaction at equilibrium when the value of the equilibrium constant is not well established.
Using the temperature approach option offsets the effective temperature used to calculate the equilibrium constant:
ln Keq = -DG/R(T + DeltaT)
In Aspen Plus, it is possible to identify if a reaction is endothermic by viewing its reaction heat. If the reaction heat is positive, the reaction is endothermic, if it's negative, the reaction is exothermic.
the Temperature approach is usually used to determine how far the real reaction is away from the equilibrium state.
If the reaction is exothermic, a positive value will make the conversion of the reaction decrease and a negative value will make the conversion increase.
If the reaction is endothermic, a positive value will make the conversion of the reaction increase and a negative value will make the conversion decrease.
Having a conversion increase from the predicted equilibrium value will not occur in practice, but the option is available.
In the following example:
CH4 + H2O <==> CO + 3 H2
The forward reaction (CH4 + H2O to produce CO + 3 H2) is endothermic, hence the reverse reaction (3CO + H2 to produce CH4 + H2O) is exothermic. In Aspen Plus, if a positive DeltaT is specified as the temperature approach for this reaction, the CH4 composition in the product stream will increase. This is because the reverse reaction (producing CH4 + H2O) is being favored since the equilibrium temperature is effectively being decreased to T - DeltaT.
The specified approach temperature is an approach to the calculated reactor outlet temperature, rather than the approach to the chemical equilibrium temperature.
The approach to chemical equilibrium temperature is NOT an approach to reactor outlet temperature.

Problem Statement: How to obtain the estimate for the equilibrium constant for an ionic reaction ?
When ionic reactions are specified in the chemistry folder, the equilibrium constant can be specified by the user or it can be calculated internally by the Aspen Plus solver using the Gibbs free energies for reactants and products, which are available in the databanks. In this case, the equilibrium constant page is displayed blank and there is no report of the value of equilibrium constant that is used in the simulation. | Solution: The equilibrium constant, Keq, can be calculated using the activities and true mole fractions for the reactants and products as follows:
In the attached file the following reaction has been generated in the chemistry folder
If there are no specified values for the equilibrium constant, by default the equilibrium constant will be calculated internally by the Aspen Plus solver based on the Gibbs Free Energies for the reactants and products.
If values are specified for A (and B, C, D, and E), these will be used to calculate the equilibrium constant Keq.
In the attached file, a calculator block has been set up in the simulation environment to retrieve the activity coefficients and true mole fractions in the liquid phase for the reactants and products.
After running the file, the equilibrium constant has been calculated to be 0.0099, or approximately 0.01 when A is specified as -4.60517 since exp(-4.60517 ) = 0.01.
If no value is specified for A, the equilibrium constant will be calculated as 1.08e7.

Problem Statement: Docker Engine is the industry’s de facto container runtime that runs on various Linux and Windows Server operating systems. Aspen Mtell Maestro is a containerized application and requires Docker Engine on the environment on which it will be deployed.
We have identified that many antivirus software (e.g. Symantec, Kaspersky, Malwarebytes) with their default configuration break Docker Engine. When this happens, Aspen Mtell Maestro containers cannot be started and Maestro Failure Agents cannot be created, trained, and deployed in Aspen Mtell.
Example:
Aspen Mtell Maestro will not go past the following step during startup:
After about 5 minutes, you may find the following warning message related to Docker in the Event Viewer app:
“Syscall did not complete within operation timeout. This may indicate a platform issue. If it appears to be making no forward progress, obtain the stacks and see if there is a syscall stuck in the platform API for a significant length of time.” | Solution: This article contains some guidelines on how to approach this problem, however, the final reSolution most likely will depend on the antivirus software and it may be necessary to contact the antivirus vendor to request information about how the antivirus need to be configured on the machine with Docker Engine.
General Recommendations
Please, follow the general recommendations made by Docker:
When antivirus software scans files used by Docker, these files may be locked in a way that causes Docker commands to hang.
One way to reduce these problems is to add the Docker data directory (/var/lib/docker on Linux, %ProgramData%\docker on Windows Server, or $HOME/Library/Containers/com.docker.docker/ on Mac) to the antivirus’s exclusion list. However, this comes with the trade-off that viruses or malware in Docker images, writable layers of containers, or volumes are not detected. If you do choose to exclude Docker’s data directory from background virus scanning, you may want to schedule a recurring task that stops Docker, scans the data directory, and restarts Docker.
Uninstalling the antivirus software
Uninstalling the antivirus software might not be the finalSolution, but it can be done to quickly confirm that the antivirus is the cause of the issue you are observing. After this test, the antivirus can be installed again and investigation can proceed on what the antivirus exceptions are and settings that need to be configured for the machine on which Docker Engine needs to be running.
Note: Disabling the antivirus is not a recommended approach to confirm whether or not the antivirus is the root cause of the issue, as disabling the antivirus may not remove the filter drivers created by it.
Symantec Endpoint Protection
Please, follow the recommendations by Symantec titled: Cannot create or launch Docker containers on Windows Server 2016 when Symantec Endpoint Protection (SEP) is installed.
To work around this issue, you will need to upgrade to SEP 14 RU1, or newer, and add the following paths as Windows File Exceptions to the Exceptions Policy at the SEPM.
Prefix Variable File and Path (Exclude child processes)
%[SYSTEM]% lsass.exe
%[SYSTEM]% svchost.exe
%[SYSTEM]% cexecsvc.exe
%[SYSTEM]% oobe\windeploy.exe
Ensure that you Choose Application Control (for the type of scan that excludes the file) and select also Exclude child processes. The new Exceptions Policy should then be deployed to the affected clients.
Note: if you were experiencing a Docker installation failure before putting these exceptions into place, you may need to uninstall the failed package before retrying.
For situations where you will be adding Windows Features to a live container, or installing a service, additional exceptions may be needed. The following example shows the exceptions to both run an MSI install and run the DNS service (Not all of these are necessary for all situations):
Prefix Variable File and Path (Exclude child processes)
%[WINDOWS]% servicing\trustedinstaller.exe
%[SYSTEM]% msiexec.exe
%[SYSTEM]% dns.exe
Kaspersky
We identified the following Kaspersky service to conflict with Docker Engine in one instance: “Kaspersky Security Exploit Prevention Service”. When such service was disabled, Docker Engine run successfully.

Problem Statement: SQLplus takes a very long time to start (10-15 minutes). Once it starts, it works normally. The same thing occurs with AspenCalc. | Solution: This is a Framework Security configuration problem. To test this out, try adding n to the command line of TSK_SQL_SERVER in the InfoPlus.21 manager. The full command line should then be 10014 n. Then restart TSK_SQL_SERVER. This disables security in SQLplus.
If this fixes the problem, you need to check the Framework security setup. Start with the HKEY_LOCAL_MACHINE\Software\AspenTech\AFW\URL registry key. Check that this is pointing at the correct security server and try to view the URL with Internet Explorer.

Problem Statement: IQ Applications disappeared from PCWS and from the APCmanage application. From iq_manage.exe command prompt, it is possible to see that IQ applications were still running and writing values to the OPC.
It is possible to have only the ACO and RTE applications running and visible in PCWS and the ACO applications visible on APCmanage.
There is an error message on the bottom of the window of APCmanage on the IQ Applications section: Application data services not running. | Solution: The root cause of this issue is that the Aspen APC Inferential Qualities Data Service was stopped for some reason, this service communicates the IQ server with the PCWS, but it is not responsible for the calculation engine of the IQ sensor itself.
The Aspen APC Inferential Qualities Data Service needs to be running in order to see IQ applications on PCWS and APCmanage.
If the service is stopped and the IQ application was started, then the calculations of the IQ sensor will continue executing but the application will stop being visible.
This can be confirmed keeping an IQ turned ON and manually stopping the mentioned service, causing the issue described previously, then in the Task Manager it is possible to see the tasks related to the IQ calculations are still running.
When the service is restarted, the IQ application should be visible again in APCmanage as well as in PCWS.

Problem Statement: It is possible to install a GDOT Web Viewer in a different server than the GDOT Online one. | Solution: Using the Installation media, it is possible to install the GDOT Web Viewer components in a different server than the GDOT Online Server.
The supported architecture for this functionality is having the SQL Server in the GDOT Online machine with the GDOT Databases, specifically GDOTOnlineHistory, already configured.
GDOT Web Viewer Server is usually located in a Demilitarized Zone or a Business Network depending on the implemented architecture.
Note that for V12.1 and earliest versions the Web Viewer service are only in the GDOT Online Server:
That is the main reason the SQL Database must be installed in the same server as the one with the GDOT Online components.
For the post-configuration of the Web Server, you must modify the GDOTOnlineWebViewerConfig.json located in C:\ProgramData\AspenTech\GDOT Online\V12.1\WebFrontEnd using a text editor to change the default IP Address to the GDOT Online Server one:
Default port for this service was set as port 8000, if the default wants or needs to be changed to a different one, modify the port on this file as well as the GDOTOnlineWebCoreConfig.txt located in C:\ProgramData\AspenTech\GDOT Online\V12.1\WebBackEnd on the GDOT Online Server:
Restart the AspenTech GDOT Online V12.1 Web Core to take these changes in consideration.
NOTE: Remember that the GDOT Online Server and GDOT Web Viewer Server must be reachable using a ping test on a Command Prompt window and the firewall rules must be specified for the port specified for the web service.

Problem Statement: How do I characterize a crude assay in Aspen HYSYS? | Solution: Characterization refers to the process in which limited input assay data is used in conjunction with estimation methods and other mathematical techniques to generate a “model” of the assay. The model allows properties to be calculated outside of the range of the available data to satisfy the needs of the planning model. It also allows assay data to be recut at any cut points required by Aspen HYSYS.
There are two options available in Aspen HYSYS for assay characterization:
Assay Manager
Oil Manager
The difference between Assay Manager and Oil Manager is explained in the following article: What are the main differences between Aspen HYSYS Oil Manager and Petroleum Assay Manager?
Note: One of the advantages of Aspen Assay Manager is that it automatically creates a Component List with Hypothetical Components and Fluid Package once an assay is entered.
Aspen HYSYS Petroleum Refining assays are added via the Assay Manager. There are three ways to add it:
Import it from a file,
Import from Aspen Library (pre-characterized assays)
Enter the assay manually.
To add the assay manually, follow these steps:
In the Properties Environment, go to Petroleum Assays folder,
Click on Add | “Manually Entered” option.
Select one of the components list from the drop-down Assay Component Selection menu.
Select the assay type: Multi Cut Properties, Single Stream Properties, or Back Blending.
Multi Cut Properties: lets you specify mass, molar, or volume cuts of the crude assay sample with user defined initial and final boiling points.
Single Stream: Lets you define the distillation percent and temperature of individual streams.
Back Blending: Back blending lets you define feed streams by blending their associated products.
Provide the necessary information and click on OK. The Input Assay form will be created. It is used to enter and edit the experimental assay data of a crude assay and consists of the following tabs:
Input Summary: Enter the property data for the whole crude and product cuts.
Pure Component: Define the pure components percentage in the overall assay.
Distillation Data: Define the distillation curve data for the whole crude and any cuts that have been defined on the Input Summary form.
After all the specifications are entered, click on Characterize Assay button in the bottom-right corner of the Assay window and wait a moment for the assay to fully compute (if manually enter option was selected, otherwise characterized results will be available immediately). To see the results, go to Conventional Results form. You can also create plots of your characterized assay from Plot Gallery in the Assay Management ribbon.
The last step is to attach the assay to the material stream in the Simulation Environment. Add a new stream, double click on it and go to Worksheet | Petroleum Assay form. Select the “Attach Existing” option and use the drop-down menu to choose the assay. Use the Conditions form to specify all the required stream properties.

BUT WAS NOT ENTERED. PARAGRAPH IGNORED.
*** SEVERE ERROR
BLOCK: CDU APPEARS IN THE FLOWSHEET, BUT
NO BLOCK PARAGRAPH HAS BEEN ENTERED FOR IT. | Solution: Aeration factor is to tune or adjust the pressure drop.
This is an adjustment factor to the aeration parameter β used in the calculation of pressure drop through the aerated liquid on a tray. Adjust this parameter to get better agreement between calculated and measured tray pressure drops. Default value is 1.
Option is available in Rating mode- TrayRating-Design/DP.
To access this parameter, turn on column targeting hydraulic analysis. Now, the input language is OK when we change the aeration factor.
(Note: This issue is raised to development team to get access this variable. Would be resolved in next release of version -V12).

Problem Statement: This KB article explains why the GDOT DR | Solution: is affected by changing the QP target for a MV even if the QP weight is zero for that MV.
Solution
For DR, the “QP Target” field on a MV is actually used to wire in the process value, or in simulation mode the currently specified value (as if it were coming from the process). For the MV penalty term we are penalizing the difference between the reconciled MV value (which in the console is displayed in the “Current” value field) and this process value (in the “QP Target” field). And yes, if the “QP Weight” is zero then this penalty term is zero, as expected. However, when this “QP Target” (actually the process value or simulated process value) changes this causes all the predicted CV values to change, which in turn alters the objective function value through the CV penalty term. This is the cause of the DRSolution changing when the “QP Target” on a MV changes (even with a zero “QP Weight”) and is the correct behavior.

Problem Statement: What is the Kinetic correlation option in a Sulsim Incinerator? | Solution: The Kinetic correlation requires that you enter the kinetic correlation.
Aspen HYSYS uses this value to calculate the conversion of CO, H2, H2S, COS and CS2 in the incinerator because HYSYS includes the oxidation reactions of these components.
So HYSYS uses the conversion equation when you specify the kinetic parameter. If you don't have this parameter, its is recommended to use the Include Stacks check box.
In this second option, HYSYS determines the Kinetic parameter based on the delta P and delta T.
So you have two options: either define the kinetic parameter, or ask HYSYS to evaluate it if you dont have such information.
The attached pdf document describes the reactions and equations used for the calculation.

Problem Statement: I would like to view / customise the VBA code related to the Aspen Utilities Planner (AUP) plug-in for MS Excel. Where do I find this? | Solution: Like most plug-ins for MS Excel, the AUP plug-in is an *.xla attachment to the MS Excel application. When AUP is installed on a PC with MS Excel, this association should be made automatically. AUP will be available as a tab in the MS Excel ribbon.
If this tab is not shown, it can be manually added to MS Excel (from the Add-in Manager, usually from the Program options) from the following location:
C:\Program Files (x86)\AspenTech\Aspen Utilities Planner V10.0\bin\Utilities360.xla
Note: the above *.xla refers to V10 so the number (360) will be different based on the version of the AspenTech Engineering suite installed.
Each of the commands in the drop-down menu refer to subroutines located in the *.xla reference. The table below shows the location of each of these subroutines in their respective modules.
Note: The *.xla is not locked and can be viewed/edited without a password.

Problem Statement: Why does the Equilibrium reactor predict carbon formation while the Gibbs Reactor does not? | Solution: Aspen HYSYS Component Database has only one kind of carbon. Carbon presents itself as different allotropes, such as C1 (Carbon-Graphite), C2 (Carbon-Diatomic Gas), C3 (Carbon Triatomic Gas), C-D (Carbon-Diamond) etc. Each one corresponds to a different free energy state. The carbon atom contained in Aspen HYSYS Component Database has a huge free energy value relative to other carbon states you may have experienced in your case.
The reason for the Gibbs free energy for carbon not to equal zero is related to the state of carbon used in Aspen HYSYS which, by default, is in the form of activated carbon. Therefore, a change in the enthalpy of formation for carbon will result in a change in the Gibbs free energy (G) for the same element. Since G=0 is assumed for all the substances at their reference state, the carbon structures away from that state will have a non-zero Gibbs free energy value.
Usually, this problem can be fixed by cloning the Carbon component, altering its first default Gibbs free energy value, and setting all other coefficients to zero (refer to Figure 1).
Figure 1. Gibbs Free Energy
We have had positive feedback from clients who have modified carbon component this way and could match literature data.
Please follow the following steps to modify carbon to use Gibbs reactor
1) From the Simulation Properties Environment, add the carbon component from HYSYS Database (as a conventional component).
2) From the Ribbon, in the Hypotheticals tab, click on “Convert”.
3) From the left column, select the component Carbon and click on “Convert to Hypo(s)”. Your component now should be already converted into a Hypothetical with the same properties as the original conventional one. (see Figure 2)
Note: In this step, the original component disappears, so if you’d like to keep the activated carbon on your component list, you will need to select and add it again as a new component.
4) Finally, double-click the cloned component. You can now edit its property data. The Gibbs free energy should now be available under the TDep (temperature dependent) tab.

Problem Statement: Can I enter pressures greater than 1000 bar or 14503.8 psi for my heat exchangers in Aspen Exchanger Design and Rating (EDR)? | Solution: Currently, Aspen Exchanger Design and Rating does not support simulations with pressures larger than 1000 bar (14503.8 psi).
Reason: EDR must be generic with respect to different shell and tube exchanger configurations and include a variety of physical effects such as entry length effects, natural convection, transition to turbulence, and most importantly two-phase flow modeling. For all these effects, a limit must be applied, since the models used for these effects may not be valid for values significantly greater than those for which they are tested/validated. In addition to this, obtaining physical properties under these conditions can be quite challenging. Furthermore, ASME regulations extend only up to 690 bar (10000 psi).
For these reasons, EDR currently does not support very high pressures (>1000 bar). This is currently being considered as an enhancement for a possible future version but is not available right now.

Problem Statement: Aspen Mtell client is unable to load and view tags from an online historian through System Manager--> Sensor Data Sources--> Map Sensors, whereas the Aspen Mtell application server is connected and able to browse tags. Users get the error message below:
Unable to load tags.
Unexpected character encountered while parsing value: <.Path, line0, position 0.
This error often occurs when the Historian OLEDB Driver service is not running. | Solution: This generally occurs in newly installed Aspen Mtell client applications. The Aspen Mtell application server may be connected to the historian and able to browse tags, but the client machine gives the above error. When this happens it is likely because the Adapter URL on the client is pointing to the wrong machine. To change the Adapter URL, follow the steps below:
1) Open Aspen Mtell System Manager on the client machine and click on the Configuration (1) tab
2) Click on Settings and then Sensor Data Sources (2)
3) Select the Sensor Data Source you are pulling the tags from and make sure the Adapter URL (3) is pointing towards a machine which has the adapter installed and configured on it (most likely the Aspen Mtell application Production or Test server). In this example, APM is my Aspen Mtell Application Server name.
Note: The client machine name should not be a part of the Adapter URL since no adapters have been configured on the client side. The adapter configuration is usually on the main Aspen Mtell server.
4) Test (4) The connection once you have changed the Adapter URL to point to a machine with configured adapter. The test should be successful if it is now pointing to the correct machine.
5) If the test is successful Save (5) the changes.

Problem Statement: How is electrical tracing of piping calculated? | Solution: The length of the tracing cable is calculated based on the pipe length and diameter. There are two types of electrical tracing:
1) E-PRO to maintain at the process temperature, and
2) E-AMB to maintain at ambient temperature.
The heat loss of the pipe is compensated by using electrical tracing cable. ACCE determines the number of circuits/ft that is needed to compensate the calculated heat loss, which is then multiplied by the length of pipe to give the total length of the tracer cable.
Note the options E-PRO and E-AMB are available from the Special pipe description drop-down selection. The electrical tracing bulks will be listed in the report under COA 792.

Problem Statement: When attempting to import an Excel spreadsheet into Aspen Flare System Analyzer, I am receiving an import error. I then get a message, Sorry, this function doesn't support excel file which is generated or edited by Excel2010. I am not using Excel2010, so why am I getting this error? How do I fix it? | Solution: Before exporting the original Flare file to Excel (.xls or .xlsx), first export to .xml and then import the .xml file to generate a fresh copy of the Flare model. This procedure can, in effect, clean up the Flare file. Once the .xml file has been successfully imported and the fresh flare model is available, save it and then export the Excel file from it again. Once the Excel file has been generated, try to import it to see if the error message has been resolved.

Additionally, SQL is requiring for the history and data collection for GDOT application. However, there could be some connectivity problem on the Database and additionally, the connection to the Database may affect the starting of Unified Agent Service. | Solution: The Unified Agent Service basically requires another important service to start which is the SQL Server Service (the name of the server will depend on the version). Every time to start the server or reboot the server make sure that the SQL Server service is running.
This service requires a Local Administrator account to run and can be set to Automatic so it can start at boot.

Problem Statement: This | Solution: provides a way to run different and multiple cases for a DMC3 Builder project.
Solution
The Model Structure of a DMC3 Builder is basically divided into two parts: Master Model and Case Folders. Inside of these Case Folders, we can create multiple cases with different vectors, parameters trials, datasets, etc.
Using this structure DMC3 builder can run a single Case that exists inside a Case Folder just by selecting the Case and Run Identify:
or Run Identify for all cases inside the Case Folder, by selecting the Case Folder Icon and Run Identify:
However, this structure by default does not allow you to select and run some specific cases at the same time for example we would like to run just CASE_1 and CASE_3. Unfortunately, there is not a default function that allows doing something like that, but we can take advantage of the described structure to perform this task.
The proposed workaround is basically creating a New Folder and create a copy of the cases that you would like to run inside that Folder.
And again, by selecting the Folder and click on identify we will be able just to identify CASE_1 and CASE_3.
Notice that Copy of CASE_1 is essentially a different case than CASE_1 (even though they have the same structure), so whatever you may change on Copy of CASE_1 will not be reflected on CASE_1

Problem Statement: This | Solution: just frames the process of Import Tag Template. Attached the equivalent Tag Templates that exist on DMCplus Build for DMC3 builder.
Solution
Tag Templates basically work to modify and create multiple tag names for multiple variables. These are particularly useful to update and change the tag names of the controllers.
In the case of DMC3 Builder tag templates require to be .xml files. In particular, we will see these files defined as xxxx.apctagtemplate.xml (xxxx = Tag Template name). this is different from the filetype use in DMCplus Build which is defined as .tcc file. Unfortunately, the structure of the .tcc file is not supported in DMC3 builder.
Manage Tag Template is the feature used to Manage everything related to tag templates (create, delete, import, export …). The Import and Export actions are useful as the xml version are compatible with other versions and allow also to be moved between servers. for DMC3 builder .xml files do not require to be saved in any specific location, just by importing them once into DMC3 builder the information will stay there.
To Import an xml file, go to Deployment > Manage Tag Template > Import. Then Select the xml that will be imported, and it will automatically appear on the Manage Tag Template window.

A file set consists of three files - the other two are arc.key and arc.dat. (SeeSolution 000077763 for an explanation of arc.key.)
An occurrence of trend data in a record defined by IP_AnalogDef or IP_DiscreteDef is 15 bytes in size holding the value, timestamp, and two quality fields. This data is stored in the file arc.dat. If a definition record has a history occurrence that is 2048 bytes or larger, this data is stored in the file arc.byte. In this case, the file arc.byte will grow larger than 128 KB.
Even if there is no data stored in arc.byte, it is an integral part of the file set and must not be separated at any time from the files arc.dat and arc.key.

Problem Statement: Thermodynamic states the relation between enthalpy (h), Gibbs energy (g) and entropy (s): g = h - T * s (where T is the absolute temperature).
When checking the stream results in conventional solid substream, one can observe the relation is not satisfied. Why? | Solution: When reporting the default stream property solid SMX for a stream, whether in the MIXED or CISOLID substream, we calculate the property as a mole-average of the solid species, because Aspen Plus handles solids as pure phases, not as solidSolutions. The value is correct.
When reporting the prop-set property solid GMX (and most likely also solid SMX) for a stream, we report the value calculated from SMTHRM as if the solid mixture were a solidSolution. This value is therefore not consistent with the entropy.
This calculation will be corrected in a future version, and a mole-average quantity will be reported instead, as is done for the entropy.
This applies to GMX and the related MASSGMX, GMX-FL. SMX and the related MASSSMX and SMX-FL.
The only exception is when the solid mixture is calculated from an RGIBBS block where solidSolution phases were considered, and the mixture is a solidSolution. In that case, the stream's solid SMX will be the value for a solidSolution, which includes the mixing term (the quantity calculated from SMTHRM).
There's a fundamental difference in the handling of the solid substream compared to liquid or vapor phases, for which there is no problem. The problem is that the solid may be a solidSolution or a mixture of pure solids. The difference in entropy and Gibbs energy is due to the fact the mixing term (R * sum [ Xi * ln(Xi)] is omitted in the entropy reported in the stream results, but the term RT * sum[Xi ln(Xi)] is included in the Gibbs energy.
The documented solid mixture property monitor, SMTHRM, returns SMX and GMX which include the mixing term. For this monitor, the solid mixture is a homogeneous phase, a solidSolution. There is no way for the user to indicate that a solid mixture in CISOLID is truly aSolution.
The attached example (Aspen Plus V12) illustrate this problem.

Problem Statement: What are the Design gauge pressure Inlet and Outlet fields for the compressor setup? What information are these fields requesting? | Solution: These fields are requesting the design (not operating) gauge pressure of the gas entering the compressor (low pressure) and exiting the compressor (high pressure). Typically, the design inlet and outlet pressures includes a safety factor over the operating pressures.
For instance, for the compressor modeled in Aspen HYSYS as shown below, the values 100 and 300 would be entered in the inlet and outlet fields above, respectively.

Problem Statement: How can I estimate Orifice Plates? | Solution: One way to estimate an orifice plate is to add an Above grade or buried pipe component and include the fitting OP | Orifice plate and union and its quantity. Set the pipe diameter as needed and note the minimum pipe length is 1 ft.
Alternatively, you may use the Equipment or Unit Cost Libraries to store the orifice plate cost data to be used in projects, as needed.

Problem Statement: How do you send all welds to shop for all equipment at once? | Solution: Construction management cost is part of Indirect. By default, Engineering management and Construction management fields are blank. To drive generation of estimated of engineering and construction management costs, a contractor MUST be specified. If there is no line item in the output report for Code of Account 82 (COA 82), it means that there was no cost calculated for this Construction Management Supervision in the project.

Problem Statement: On the General Wage Rate/Productivity-IP Box under Project Basis View, I entered manually all the Craft Wage Rates for all the craft code. Now I need to reduce the wages by a percentage (%). Instead of revising all the wages, is it a possibility to just reduce the wages by a percentage basis? | Solution: Yes, it is possible to reduce the wage rates in one field. This however requires creating a new construction workforce (CWF).
Let's say, CWF #1 was created previously, where the craft wage rates are defined.
Now, create a second CWF and adjust the craft wage rates as a percentage of CWF #1 as follows:
Note: Make sure CWF#2 is now linked properly with the contractor as opposed CWF#1.

Problem Statement: Why does changes to the Total Construction Weeks change the Total Project Costs? | Solution: The construction schedule is integrated with the cost estimate to provide the basis for estimation of schedule-dependent costs such as equipment rental requirements, field supervision and construction management. Because of this dependence, changing construction weeks will impact the project total costs.
Additional discussion on the interdependency of project schedule and cost is available in the ICARUS reference guide (Help > Documentation) under chapter 36.

Problem Statement: How do I create a Code of Account (COA) exception and when should it be used? | Solution: Consider a scenario where you want to allocate fittings on a pipe, such as valves and bolt-up connections, to a different COA other than pipe erection. This can be accomplished by creating exceptions in the Code of Account. In this example, to allocate these to a different COA, you will have to create exceptions to COA 317 (CS Pipe Erection) using subtypes 10 (Erect valves) and 11 (Bolt-up connections). Before creating a COA exception, you will notice that the CCP (or CCI) report indicates that costs associated with these fittings are reflected in COA 317.
How to create a COA exception?
Select the COA file where you would like to add an exception, and then choose Allocations. The COA Allocations window will pop up.
You need to have the COA allocation first and then have another line that defines the COA exception to the generic allocation.
Click Add at the top to insert a line below it to create the exception to the generic rule. Let's say we want to allocate these costs to a different COA, which is 392 (Pipeline-Valves, Fittings). The COA exception flag has to be set on the exception line. Also on the exception line you have to define what the exception applies to. In this case it applies to subtypes from 10 to 11. You can similarly create exceptions that apply to specific material or COA modifier or diameter etc. The exception line doesn't have to be right below the COA allocation line. You can add it all the way in the end and it should work OK.
To see the different subtypes, where you can apply exceptions, please refer to Icarus

Problem Statement: Is there something to consider for leaving the equipment as it is? This is not demolition, this is a component already present in the project but does impact the cost because of the connections and so on that will be different. | Solution: For an existing equipment, select “EXIS” as the installation option field of the component.
For additional cost associated with this component, you can then use the “Mat’l/ man-hours additions” form from the “Options” drop down menu.
Other installation options are explained on article 97099.

Problem Statement: How do you send all welds to shop for all equipment at once? | Solution: There is no direct way to send all welds to shop. You can select “RMT” in the project basis view but if the length exceeds the limit, some of the weld will be done in the field.
However, for each piping component, you can put 100% in the “Percent of welds in Shop” under Options > Pipe -Item Details.

Problem Statement: When I change Percent calculated hours for Home office construction services, under Engineering Workforce | By Phase, it seems to have no effect. | Solution: Home office (HO) construction services are calculated based on the engineering workforce (EWF) performing the task. To capture any customization of costs for home office construction services, the EWF needs to be linked for the contractors doing the installation (see below).
Otherwise, the system is going to use the Out of the Box (OOTB) HO model and will not apply any adjustments.

Problem Statement: How do I restore the missing tabs in the palette window and Project Basis View forms? | Solution: After the installation of Aspen Capital Cost Estimator (ACCE) V8.0 and above, the user is required to check whether the resiliency (configuration for first time use) is successful. Default folders and shortcut under My Documents will be created and if resiliency fails to set-up these folders properly, users may end up losing some tabs and looking at a blank Project Basis view.
There are few possibilities why this could happen:
1. Insufficient disk space which prevent the resiliency to complete successfully. Software will give warning if this step is not successful, and user will not be able to use ACCE.
2. Insufficient write permissions in the My Documents redirect to the drive where ACCE default folders would be created.
3. Corrupted registry due to previously installed version which does not co-exist with the version installed (ex. V8.7.1 and V8.8).
The workaround for each scenario follows:
1. Free disk space to allow resiliency to complete.
2. Some users have very limited permissions setting. We suggest requesting their IT to give write permission rights for the folders where ACCE default folders will be created. Refer to the word document for the location of the default folders.
3. If users have installed V8.7.1, they have to un-install and clean up registry before installing V8.8.
Alternatively, rename or remove the registry folder 40.0 for V12.0 (this number will be different for earlier versions i.e. 39.0 for V11.1, 38.0 for V11.0, 34.0 for V8.8 and so on) then re-start ACCE to start over resiliency. This folder 40.0 is located at HKEY_CURRENT_USER/Software/Aspentech/Aspen Icarus Products. User with limited permission rights might need their IT with admin rights to perform this task.

Problem Statement: Why does Datasheet Definer Tab disappear in Excel?
In some occasions, when I open Datasheet Definer I am getting the following error message:
Note: If the Datasheet Definer Ribbon is unavailable after a recent installation of Aspen Basic Engineering, the ABEDefinerAddIn may NOT be loaded yet. To find more details on this issue and how to resolve it, please see knowledge Base (KB) article 97593. | Solution: If you are seeing this error message or not able to display the Datasheet Definer tab, make sure that AZDatasheetDefiner Add-In is not disabled in Excel options. Excel can disable an Add-In if the trust or security settings enabling it to run were not previously set, or if Excel is terminated by the Task Manager or crashes when the Add-In is running.
You can check it by following these steps:
1. Start Microsoft Excel
2. Go to File > Options > Add-ins
3. In Excel Options windows choose Add-Ins from left hand side and in Manage drop down box select Disabled items as shown in screenshot below and click on Go button. This will show Disabled Add-ins and you can enable it if AZDatasheetDefiner Add-In is in this list.
Once you do above steps, make sure you re-start excel by closing all excel file on your computer and make sure in task manager that Excel.exe process is not running.
Additionally, the Datasheet Definer may not have been installed properly due to a known issue with Office 2016. In this case, you won't find the Add-ins under the Disabled Items list. To correct the issue with Office 2016, please refer to the following article:
