Problem Statement: How does Aspen Shell & Tube Mechanical v8.4 calculates Flanged & Flued expansion joints? | Solution: If the option TEMA F and F EJ Line Element FEA interface option is selected as Yes under the Exchanger Geometry|Expansion Joints|Expansion form
Aspen Shell & Tube Mechanical uses the TEMA flanged-and-flued (thick wall) expansion joint Line Element Finite Elemente Anaylsis software, obtained directly from TEMA. The calculation will be in accordance to TEMA 9th edition
When the LE FEA program is not available or the TEMA F and F EJ Line Element FEA interface option is selected as ‘No’ or ‘Program’, then Aspen Shell & Tube Mechanical uses TEMA 8th edition, which has the design of flanged-and-flued expansion joints using a closed-form algebraic solution

Problem Statement: When transferring data from the Hetran Program to Aspen Shell & Tube Mechanical, some loss of data is experienced. i.e. data from main materials disappeared and the format of some tabs has changed. | Solution: This problem appears when the original file from Hetran is using the option "Other" as a design specification for the code and this option is not included in Aspen Shell & Tube Exchanger. To transfer the data correctly the following steps need to be taken.
1. In Hetran, go to Input | Design data | Specifications and in the Design specifications tab, change the design code from "'Other" to "ASME" (you will be able to change it back later).
2. Run the simulation in Hetran and then transfer the file to Aspen Shell & Tube Mechanical with the option "Clean up selected application(s) before transfer" checked.
3. Open the file with Aspen Shell & Tube Mechanical, verify that the list of materials is present.
4. Change the design code accordingly (e.g. EN) in Aspen Shell&Tube Mechanical Input | Problem Definition | Application options in the Code and standards tab
5. Run the simulation in Aspen Shell & Tube Mechanical. Results are now shown in the correct code.Â

Problem Statement: What is a log file in EDR? | Solution: Is a text file that contains a track record of the internal calculations. This feature only works with Shell &Tube Mechanical. To create a log file you need to go to Tools|Program|Execution Settings|Execution and check the option 'Create a log file for calculation engine
This setting creates a Log file with the same name as the EDR file:
The log file (attached) contains one line for each time the program visits a routine that contains the TRAC keyword. The number at the end of the line is the component number (1=shell, 38=tubes, etc.) that the program is calculating. This was originally done only for internal use to trace the program operation. It is a relatively quick way to see where the program is hung. However, if the program is in an infinite loop, the LOG file becomes gigantic since the program never stops writing out the log file. Here is the beginning of the attached log file. The first part is the subroutine name with a description.

Problem Statement: How do I specify the the longitudinal location for nozzles in Aspen Shell & Tube Mechanical? | Solution: The nozzle locations are specified as axial distances from the front face of the front tubesheet reference point. All numbers should be positive. The nozzle location can be specified at Input | Exchanger Geometry | Nozzles-Details-Ext.Loads | Penetr/Proj/Distances under "Distance Nozzle CL"
If the program is having trouble outputting the correct nozzle location, then navigate to Inputs | Exchanger Geometry | Nozzles-General. Fine tune the overall range locations (1-9) by using fractions in the nozzle location specification.

Problem Statement: Why is the static pressure at the PSV outlet (PSV Backpressure) different with and without "Rated flow check" and "Rated flow for downstream nodes attached to tailpipes"? | Solution: When you check rated flow for tailpipe check, per API guidelines, the pressure drop correlation uses rated flow rate rather than required flow i.e mass flow rate. This is a modified pressure drop correlation but the energy & mass balance are still performed using required flow i.e mass flow rate
When you make mass flow = rated flow, both pressure drop correlation as well as energy & mass balance equations use the same value.

Problem Statement: Why are there inconsistencies in the component compositions of the inlet and outlet flow of a knock out (KO) Drum? | Solution: Inside the KO Drum when the entire inlet is liquefied with zero outlet flow. Severe solver convergence can occur due to this zero outlet flow from KO drum. In order to avoid this issue, flaresystem analyzer solver puts a very tiny artificial flow at the outlet of KO drum and by default it is set to 100% of the 1st component.The composition of this flow can be specified by the user in the composition tab of the KO drum.

Problem Statement: How do I convert the Start Date and End Date columns in the Raw Data tab of the Monthly Report to the local time?
*The Monthly Report spreadsheet is one of the usage reports provided to customers through the AspenTech support website.
*If you do not know how to access the Monthly Report, please see KB article 145209 for instructions on how to access and download the usage reports from the AspenTech Support Website. | Solution: This KB explains how to covert the Start Date and End Date columns in the raw data tab of the Monthly Report available through the AspenTech Support website, which by default is in UTC/GMT time zone, to the local time zone.
The Start Date and End Date columns (columns J and K on the Raw Data tab, respectively) can be easily converted to local time.
1. Right-click on the column J at the top of the column and click on “Insert” from the drop-down menu. (a new blank column J should have been created to the left of the now re-labeled column K.
2. In the new column J, in cell J2, type in the formula “=K2+({local time difference in hours from UTC/GMT time zone}/24)” or "=K2-({local time difference in hours from UTC/GMT time zone}/24)”, depending on whether the local time is ahead (+) or behind (-) UTC/GMT time. Press Enter.
3. Click on cell J2 so that is it highlighted and double-click on the tiny black box in the bottom right corner of J2. The formula should populate down the entire column.
4. Repeat steps 1-3 for the End Date in column K.
5. Delete the old Start Date and End Date columns to avoid confusion.
6. The new Start Date and End Date columns will now have the local time of the region that corresponds to the time difference from UTC/GMT time.

Problem Statement: How do I get the charts/graphs in the Monthly Report to display more filtered, specific data (e.g. data for only one specific server)?
*The Monthly Report spreadsheet is one of the usage reports provided to customers through the AspenTech support website.
*If you do not know how to access the Monthly Report, please see KB article 145209 for instructions on how to access and download the usage reports from the AspenTech Support Website. | Solution: This knowledge base article describes how to filter the data in the monthly usage report provided by AspenTech so that the charts/graphs will display more filtered, specific data that the user can specify (e.g. data for only one specific server).
The monthly usage report is an Excel spreadsheet that contains multiple tabs that alternate between Data and Chart information for various metrics, such as PeakTokens, MaxSimUsers, UsageHoursByFeature, etc.
Each Data tab is linked to its corresponding Chart tab of the same name, such that whenever data is filtered or changed on the Data tab, the Chart tab will continue to reflect the data in a chart and will change, as well.
Each Data tab has drop-down boxes that can be used to changed the different variables being measured, and thus, utilized in the Chart tab.
For example, if you wanted to change the UsageHoursByFeature Chart to only display data pertaining to one specific server instead of all servers, you can click on the drop down box next to Server and change from All Servers to a specific server.
The corresponding Chart tab will then change to display only the data pertaining to that specific server.

Problem Statement: Does the Resolve method work on parameters? If yes, how do I declare it? | Solution: Usually, Resolve is used to access variables in any given block, stream, or the flowsheet itself from a script anywhere in the simulation. However it can also be used to access parameters in ACM simulation.
The convenient way to declare is to breakdown the code in terms of Block and Parameter names. For example:
BlockObj = FlowsheetObj.Resolve("Block name")
VarObj = BlockObj.Resolve("Parameter")

Problem Statement: Does the capability exist to design a "Cooler Box" type of heat Exchanger? | Solution: Cooler Boxes are used in oil refineries for cooling very heavy oil streams (such as heavy vacuum distillates or resides) against cooling water, without getting the material too cold.
Unfortunately this type of heat exchanger cannot be made . There is really no easy way to model a coiled rectangular shaped bundle with a liquid flowing on the outside of the bundle with any of the EDR products. Aspen Air Cooled Exchanger is the best fit but it can't deal with a liquid outside the bundle.

Problem Statement: Aspen Air Cooled Exchanger does not allow me to input the desired tube pitch and layout angle. When I enter my inputs, the layout angle cell turns red. If I run the simulation, I get Input Error 8002: Input for Tube layout angle is beyond the permitted range. | Solution: The issue with the tube layout angle has to do with the program's bundle geometry calculation. Given 2 of the following 3 specifications: Transverse pitch, Longitudinal pitch, and Tube layout angle, the program will calculate the third. For example, if the longitudinal and transverse pitch are both 2.5 in, then the tube layout angle must be 26.6 degrees. If you delete the Tube layout angle specification, then the value will be automatically calculated and displayed in red.

Problem Statement: Why do I get a message “TST: cannot open BIN file” while trying to run Aspen DMC plus extract to extract a BIN file? | Solution: In the initial stages of Aspen DMC plus implementation project, the plant data is collected to build a final Aspen DMC plus controller model. Aspen DMC plus extract is the tool used to extract data from collected data. The real time collected data from process unit is stored in form of a BIN file. The BIN file has all the tags and sample information for all process streams.
Aspen DMC plus extract is a DOS command which is used to extract the collected data in CLC format. This CLC file is then the input file for Aspen DMC plus model.
At times while using DOS command for extract for data extraction, error “TST: cannot open BIN file” appears even when the correct BIN file name is mentioned.
The reason for this error could be-
a) Incorrect or incomplete path specified for the BIN file,
b) Incorrect BIN file name specified.
The correct format for DMC plus extract is :

Problem Statement: Why am I unable to insert a "snapshot" of other applications and paste them into Excel datasheet editor sketch cells directly? | Solution: When you insert a "sketch" to Excel, you actually insert an object using OLE (Object Linking and Embedding). That means you are actually linking another application to Excel. Examples of other applications are: Microsoft Word, Adobe Acrobat Reader, Microsoft Paintbrush and any other application that supports Object Linking and Embedding.
OLE implementations in all applications are different. Some support OLE better, some worst.
When you use a "snapshot" of another application's window and paste the snapshot to Excel, Windows inserts/links Microsoft Paintbrush application as an OLE object. Microsoft Paintbrush OLE implementation is very limited application for programming purposes. It doesn't allow you to extract a .BMP to save it as a file when inserted to an OLE container using the OLE only API.
The code for workbench (legacy datasheet editor) can access a very low level Windows API, so you were able to find a workaround for this problem and extract/save .BMP file (to workspace ) without use of OLE API. But Excel doesn't allow to use low level API.Therefore, it is impossible to extract and save corresponding .BMP file in workspace. We cannot guarantee all OLE objects can be embedded because both sides must interact properly.
The workaround is to copy the "snapshot" to Microsoft word document and insert it as an object.

Problem Statement: AZ demon is not working for items that were created previously to the AZDemon compilation into the workspace. | Solution: The Demons are rules that automatically load when an action is triggered inside the Workspace (WS). When you compile the information you will not be able to apply these rules on items that were created previously to the Demon compilation.
To fix this behavior you will need to go to the Rules Editor Interface and then load the WS you are working on, after the message saying that the WS was loaded, please select Tools-->Reset All Demons in order to apply these command to all the items of the WS, either they were created before or after the Demon installation.

Problem Statement: How do I transfer a previously created Simulator Interface File (PSF) file into Exchanger Design and Rating (EDR) programs? | Solution: A Process Simulator File (PSF) file is a file that contains both process and physical property data that enables data generated by a program (normally a process simulator) to be transferred to an Exchanger Design and Rating (EDR) program.
Once a PSF file has been created, the procedure to import into EDR programs is as follow;
1. Open any EDR program and then select either a new case or an existing case.
Note: If you are using Aspen Plate Fin Exchanger or Fired Heater, then from Input | Problem Definitions | Application Options, set the Number of Streams.
2. From the main menu at the top of the program, select File, then Import from and the PSF file. Navigate to the location where the PSF file is saved and select it.
3. Once the psf file has been selected, the "Import PSF Data" screen will pop up.
4. Properties can either be transferred at one, two, or three pressure levels and this can be set in the "Use Properties" column, by clicking on the scroll down button.
5. From the "Import to" column, the stream number to which you want to import the data to can be selected. Press the OK button.
6. Open the Input | Problem Definitions | Process Data and Input | Physical Properties Data | Stream 1, 2 or 3 Properties where process data (temperatures, mass flowrates and pressures) and "the physical property data will have been transferred from the PSF file.
Important Note: When importing a PSF file it will not clear any existing process or property data but overwrite. Therefore if the existing file has physical property data for example at 12 temperature points and the new file only brings in 6, then the program will still display 12 temperature points where the last 6 are from the old case. Therefore, it is advised that the process data and physical property data screens are blank before importing a PSF file.

Problem Statement: How to interpret Warning 1325 is regarding how Aspen Shell & Tube Exchanger? | Solution: Operational Warning 1325 is regarding how Aspen Shell & Tube Exchanger (Tasc+) handles "Number of tubes submerged in horizontal shellside condensation", the details of which can be found in RS1069 in HTFS Research Network. If fraction of submerged tubes is not provided, EDR estimates the fraction based on a pressure drop balancing method. The estimation is checked against a required fraction of submerged tubes based on thermal considerations.
Some relevant information for these two fractions is as below:
* The 5% is "required fraction of the surface area for cooling the liquid". More details of "The required fraction of the surface area for cooling the liquid" can be found on Page 32 of RS1069 in HTFS Research Network.
* The 44% as "naturally submerged tube fraction" is calculated using a balanced pressure drop mode, involving calculations of parameters, like entrainment ratio, two-phase pressure drop multiplier etc. More details of the method can be found in RS397 and RS784 in HTFS Research Network.
The balanced pressure drop model depends on the amount of liquid and the relative densities and viscosities of both liquid and vapor phase. HTFS Research Network DR12 (Gloyer 1970) indicates it is based on frictional loss of turbulent flow of both phases through a similar resistance (the tube bundle) with vapor at the top and liquid at the bottom, and the same pressure gradient along the exchanger in each. Baffle pitch affects both phases, so does not change the relative resistances. The model does not allow for additional gravity induced drainage of the liquid (so no dependence on nozzle size), or drainage notches, or any specific geometric features, such as there being more/fewer tubes per unit cross section in the liquid or vapor regions.
The "pressure balanced" fraction is an estimate by the program, and if it is considerably greater than that of "required for liquid cooling", a warning message would be generated. the initial estimate is provided iteratively in Input | Program Options | Thermal Analysis | Heat Transfer tab until the subsequent "required fraction for liquid cooling" matches this initial estimate.

   Sub Main()
       'Launch Application and open case
       Dim hyApp As Application = CreateObject("HYSYS.Application", "")
       'This case has a heat exchanger on it named "E-100" which is rigorous

       Dim exch As HeatExchanger = hyOps.Item("E-100") 'Get the heat exchanger
       Dim bdExch As BackDoor = exch 'create a backdoor to access variables with monikers
       Dim foulResHS As RealVariable = bdExch.BackDoorVariable("ExchPerf.500/ExchangerDesign.300/HTFSplusCalculation.300:ExtraData.823.0.(FoulRes)").Variable
       Dim foulResCS As RealVariable = bdExch.BackDoorVariable("ExchPerf.500/ExchangerDesign.300/HTFSplusCalculation.300:ExtraData.823.1.(FoulRes)").Variable
       Dim foulResUnits As String = "C-h-m2/kJ"
       'Get the value that is already in the variable
       Dim hotFoulRes As Double = foulResHS.GetValue(foulResUnits)
       Dim coldFoulRes As Double = foulResCS.GetValue(foulResUnits)
       'Set new values in the variables
       foulResHS.SetValue(1, foulResUnits)
       foulResCS.SetValue(2, foulResUnits)

Problem Statement: For the case of shells in series, how about the pressure drop of the connecting lines b/w the equipments? Is there any specific consideration to be aware of? | Solution: If the exchanger design ended up with some exchangers in series, we assume that these exchangers are located pretty close together to minimize the heat loss and the overall pressure drop.
Generally, the pressure drop in the connecting pipes (between exchangers in series) is way smaller than the pressure drop that occurs in the exchangers (expansion/contraction in nozzles and tubes, flow through the bundles, flow separation over baffle cuts...). It is a common and acceptable assumption to neglect the pressure drop in the connecting pipes. Similar assumption is taken in heat transfer loss from shell to the environment (again because this loss is much less significant than the heat transferred between tubes and the shell).

Problem Statement: Does Aspen Shell & Tube Exchanger account for the pressure drop in piping between multiple shells in series? | Solution: If there are multiple shells in series, Aspen Shell & Tube Exchanger assumes that these exchangers are located close together to minimize the heat loss and overall pressure drop. Generally, the pressure drop in the connecting pipes (between exchangers in series) is much smaller than the pressure drop occurs in the exchangers due to expansion/contraction in nozzles and tubes, flow through the bundles, and flow separation over baffle cuts.
It is a common and acceptable assumption to neglect the pressure drop in the connecting pipes. A similar assumption is made in heat loss from shell (and external piping) to the environment. This loss is also much less significant than the heat transferred between tubes and the shell.

Problem Statement: A graphical technique for assessing the stability of a thermosiphon circuit is outlined in solution 139174 “How can I interpret the thermosiphon stability assessment from Aspen Shell and Tube Exchanger?” In this method, pressure drops are calculated around the thermosiphon loop and then graphs are used to determine if the unit may operate stable or not.
The Shell & Tube program presents pressure drops for the inlet circuits, exchanger and outlet circuits from the Results | Thermal / Hydraulic Summary | Pressure Drop forms, where the solution describes how the pressure drops can be used for the stability analysis. | Solution: For a thermosiphon run, additional results are presented in the Results | Thermal / Hydraulic Summary | Pressure Drop forms as shown below;
The different colored boxes represent the pressure drop components that can be summed together, where as indicated in Table 1 of TM16;

Definition
Green
Pressure drop due to friction and acceleration only between the upstream point of constant pressure (0) and the inlet to the heated section (1). The gravitational pressure drop is not included in this term. Pressure drop due to any valves or pipe fittings in the pipe should be included.
Red
Pressure drop between the inlet to heated section (1) and the outlet of the heated section (3) due to friction only.
Yellow
Pressure drop between the outlet of the heated section (3) and the downstream point of constant pressure (4) due to friction. Note this should also include the pressure drop caused by any valve or pipe fittings in this section.
Blue
Pressure drop between the inlet to the heated section (1) and the outlet of the heated section (3) due to acceleration only.

Problem Statement: Why do the pressure levels have the same value when importing properties from Aspen HYSYS to EDR? | Solution: The problems is when the PSF file is creating in EDR, EDR takes the inlet pressure and outlet pressure reported in the Aspen HYSYS exchanger in order to generate the Pressure Levels. The issue is that the pressure drop specified in the Hysys exchanger was zero, the pressure levels have the same value. With the same value for the two Pressure levels EDR can cannot interpolate any value for the properties causing an error.
The solution is do not specify a delta zero or the same pressure for the inlet and outlet stream in the Hysys exchanger, also the value of zero for a real exchanger (EDR) is not logical.

Problem Statement: Aspen FRAN is used for modeling the thermal performance of conventional closed loop shell and tube feedwater heaters used in power plant applications. It rigorously models and rapidly resolves complex interactions of desuperheating, condensing and subcooling zones and high-pressure feedwater.
The program has been part of the Exchanger Design and Rating (EDR) suite since aspenONE V8.0, and can be run expanding “Other” from new. This option is only available for V8.0 and V8.4.
The extension for the FRAN input is *.fri, where this solution describes how a file association can be set so that when a FRAN input file is double clicked, the program is opened automatically. | Solution: To manually associate a file type to a program in Windows 7:
1. Run Control Panel | Default Programs
2. Run “Associate a file type or protocol with a program”
3. Select .fhi from the extensions list and click on the “Change program button”
4. Browse to Fran.exe, that will normally be in the folder “C:\Program Files (x86)\AspenTech\Aspen HTFS V8.x\Aspen FRAN V8.x” and select Fran.exe. Click Open, then OK.
If the file extension has not been registered on the computer, then it will not appear in the list in step 3 above. If this is the case then;
1. Double-click on the file extension. You are presented with a dialog that states the extension is unknown, select "Select a program from a list of installed programs" and click OK.
2. Click the Browse button and browse to Fran.exe (normally “C:\Program Files (x86)\AspenTech\Aspen HTFS V8.x\Aspen FRAN V8.x”) and select Fran.exe.
3. Check the "Always use the selected program to open this kind of file"
4. Click OK.
Now when the input file (*.fri) is double clicked, the FRAN program should be started and the file opened.

Problem Statement: How do I determine the back door monikers for EDR variables? | Solution: Determining the monikers for variables that the user may want to access with a BackDoor is often difficult/tedious but can be done with the script manager, or by going through CS&T to ask a developer who can directly observe the monikers. There are the monikers using the script manager as follows:
1. Open a HYSYS case with a rigorous heat exchanger
2. Open the exchanger and navigate to the Rigorous Shell & Tube tab and the Process ply (this is so that the variables I'm interested in are already visible and open in the view in front of me, to make the script a bit simpler)
3. On the Customize tab, click Script Manager
4. Navigate to a non-read only folder to save the script using the Directories window and [..] to move up a directory
5. Click "New..."
6. Enter a name for the script, e.g. "EDRVariableMonikers"
7. Click "Record"
8. Right click on the Fouling Resistance variable value for a stream in the Process Data Matrix and select "Send To > Data Tables > Create New" (This will write to the script a message that tells the engine to create a process data table and add this moniker to it, displaying the moniker in the script).
9. Repeat 8) for any other monikers of interest, but you must remember the order in which you added them
10. Open the Script Manager again from the Customize Tab
11. Press Stop Recording.
12. Open the script which was saved in the location from step 4) in a text editor such as Notepad
13. The script should have a line similar to this: Message "ProcessDataTable.300(ProcData1)" "DropToAddCSVariable \"FlowSht.1/UnitOpObject.400(E-100)\" \"ExchPerf.500/ExchangerDesign.300/HTFSplusCalculation.300:ExtraData.823.0.(FoulRes)\"" This line designates that the ProcData1 datatable will have a variable added to it from the unit op E-100 at the moniker "ExchPerf.500/ExchangerDesign.300/HTFSplusCalculation.300:ExtraData.823.0.(FoulRes)"--this is the hot side fouling resistance.
For step 8) many different actions could be done to expose the variable's moniker, such as entering a new value into the cell, sending the variable to a different utility, or many other things. I chose to send to data tables because the script tends to be a bit cleaner from this. This sequence should work to identify backdoor monikers for most situations, but sometimes certain variables may be a bit more complicated.

Problem Statement: When running Aspen Shell & Tube in simulation mode, I am unable to change the TEMA type. When I change the TEMA type input and run the simulation, the program reports the old TEMA type in the results. | Solution: This issue arises when the exchanger geometry inputs do not meet the requirements for certain TEMA types. For example, T or S type rear heads require a full support baffle that might not fit in the current baffle arrangement.
This problem can be solved by changing the Tube Layout under Input | Exchanger Geometry | Geometry Summary to New (optimum) layout as seen below. This will resolve the inconsistency that does not allow the particular TEMA type specification.

Problem Statement: How do I model a jacketed pipe? | Solution: A jacketed pipe consists of two concentric tubes, one inside the other. Hence, from a thermal point of view, a jacketed pipe can be analyzed as a tube-in-tube heat exchanger1 (i.e. double pipe heat exchanger). The allocation of the hot fluid and cold fluid depends on the application. For instance, if you want to maintain the conveyed fluid hot (e.g. molten sulfur transport) the heating medium (steam, hot oil, etc.) will flow through the annulus or jacket and the conveyed fluid through the inner pipe.
A jacketed pipe can be modeled in Aspen Shell & Tube as a Double Pipe exchanger using a B-D (Double pipe)-M TEMA type exchanger.Â
In the enclosed example hot air flows through the inner tube and cold water through the outer tube and the flow arrangement is parallel. One of the assumptions in the thermal model is that the exchanger is insulated (i.e. no heat transfer occurs between the outer tube fluid and the surroundings).

Problem Statement: How pressure changes in distributors? | Solution: The total pressure change in a distributor is determined from the frictional loss in each pad, and the loss associated with turning and the change in flow area at the inlet to and outlet from the distributor, and between the pads, if there are two of them. The pressure change in distributors is thus calculated rigorously using this method in all calculation modes. Gravitational changes are included when appropriate.

Problem Statement: Why are the surface area results different between V8.0 (and older versions) and V8.4 for a Plate Fin Exchanger for the same exchanger geometry input? | Solution: In V8.0, the Main surface area that was reported for Checking/Simulation modes was the sum of the main fin (Results|Mechanical Summary|Exchanger|Stream Geometry), distributor, and redistributor areas. In V8.4 a change was implemented so that the Main surface area is only the main fin area.

Problem Statement: How heat transfer occurs in distributors? | Solution: Heat transfer in distributors is a calculation option in simulation/checking modes: By default it is on. The calculation grid in these modes includes any Distributor-only region at the ends of the exchanger. Heat transfer in distributors is not allowed for in Design Mode. The calculation grid here covers only the heat transfer region of the exchanger.
In Simulation/Checking, there is a single axial grid along the exchanger. Each stream is assumed to enter the calculation grid at one specific point. For an end entry or exit distributor this point will be the first or last on the axial grid. For a side entry/exit distributor the entry/exit point is assumed to be half-way along the side-bar entry gap. The axial flow length of the distributor on the calculation grid is thus typically half the real distributor length for these cases. This distinction is allowed for in allocating distributor pressure loss and enthalpy change to points in the distributor region.
For heat transfer calculations, the mass flux between the inlet and outlet of the distributor is assumed to change uniformly with axial distance along the exchanger. This approximates the physical situation in which there is a step change in mass flux between the distributor pads, but the change happens at different axial locations, depending on the transverse location across the exchanger. All distributor heat transfer calculations assume that the two distributor pads use the same finning. This is usually the case, but when it is not, it means that heat transfer calculations are making an approximation that pressure drop calculations do not.
Distributor heat transfer depends not only on heat transfer coefficients, but on two area factors: the fraction of the (rectangular) distributor region occupied by active distributor finning, and the extent to which the active finning in one distributor overlaps with the active finning in other layers. The first of these is readily evaluated for each distributor. The second, overlap with other layers, is harder to determine, so an approximation is used. Local heat transfer coefficients in distributors are first converted to coefficients based on parting sheet area (with the normal allowance for fin efficiency and primary and secondary fin area) and then further multiplied by an area factor to give effective distributor heat transfer coefficients. The area factor varies from unity at the point where the distributor fin and main fin meet, to a lower, or even zero value at the overall stream inlet or outlet point.
In the stream details output, the actual and effective heat transfer coefficients are tabulated and each can be plotted as a function of length along the exchanger. It is often seen that local distributor coefficients get higher towards the overall stream inlet and outlet points (because of the higher mass flux there), but the effective coefficients get smaller, because of the reducing area factor.
When distributor heat transfer is switched off, local heat transfer coefficients in the distributor are still calculated, but the effective coefficients are set to zero. It is straightforward to evaluate the effect of distributor heat transfer, by running the case with and without this heat transfer switched on.

Problem Statement: How to simulate a horizontal fin (also known as hardway fin) in Aspen Plate Fin Exchanger. | Solution: Horizontal fin which also known as Hardway Fin in Plate-Fin Exchanger. Normally it is used to improve the flow distribution across the layer width at the stream inlet part.
Hardway fin can be specified in a short region at the stream inlet in Design mode.
It is either serrated or perforated finning laid transversely to the normal flow direction.
Similar to Main fin, both the fin number and the length of the hardway fin need to be specified. The fin type can also be used elsewhere for normal (axial) flow.

Problem Statement: How do I simulate a Multi-bed Flow sheet in Aspen Adsorption? | Solution: There are two ways to simulate a multi-bed flow sheet.
1. Single Bed approach: This approach is valid if the following conditions are met.
· Each absorbent bed is identical (Absorbent layers, model assumptions).
· Only one bed has to be rigorously modeled.
· We can incorporate any number of interactions.
· Material sent to an interacting bed (stored) is reused (replayed) later in the cycle.
The benefits of using the single bed approach are listed below.   Â
· No detriment to simulation accuracy.
· Increased simulation speed. We are going to solve fewer equations.
· Less data passed between client and server and server to plot/result files.
· Simplifies the setting up and configuration of the model.
2. Multi-bed approach: If the Single Bed approach cannot be used for a given process, a rigorous multi-bed flow sheet can be created. It contains more than one bed model. It is useful for control studies and more difficult to configure, having longer execution times. We can find N2PSA example in the examples folder (C:\Program Files (x86)\AspenTech\Aspen Adsorption V8.4\Examples\N2PSAMB) which uses rigorous multi-bed approach.

Problem Statement: How to plot an isotherm. | Solution: We suggest the following procedure:
1. Create a new simulation and set up the component list (or reuse your existing simulation case)
2. Create a block using the Static_Isotherm block
3. Select the isotherm and enter the parameters
4. Change the run mode to "Dynamic"
5. In the Run Options, set the communication time to 1 second, the pause at time to 100 seconds
6. In the Solver Options, Integrator, select the Implicit Euler method, select the fixed step method, set the step to 1 second and uncheck the option "interpolate at communication intervals"
7. In the flowsheet constraints, add the following code:
CONSTRAINTS
// Flowsheet variables and equations...
Pmin as pressure (fixed, 1e-5);
Pmax as pressure (fixed, 4); // set the upper value for the pressure
// vary the pressure
// you need to make B1.P free
B1.P = Pmin + time/100 * (Pmax - Pmin);
dummy as realvariable (initial);
$dummy = 1;
END
8. Right click the flowsheet constraint text editor, and select "Compile" (or press F8). The simulation will be overspecified by 1
9. In the static isotherm block, AllVariables table, make the pressure free. The simulation should become again "square" (0 degree of freedom, "green square" status)
10. Create a time plot with B1.P as the x axis (drag & drop the variable on the X axis), and B1.W("N2") (or other components) on the plot
11. Run the dynamic simulation
You may need to close and re-open the plot to see the correct results.

Problem Statement: Sometimes building a VBA code for an Excel file that uses ASW may require Excel to hold the execution of the VBA commands while HYSYS/Aspen Plus solves the simulation and ASW updates the results. How can this be done? | Solution: Normally you could use the commands Application.Wait() and Sleep() to hold a VBA code execution, however, for this case this would not be useful since that also holds Aspen Simulation Workbook and the simulation results would not be updated.
In such cases you would need to use a DoEvents loop that will delay the VBA code without stopping ASW, thus allowing it to update the results from the simulation.
The DoEvents subroutine for this would be:
Sub WaitFor(NumOfSeconds As Long)
Dim SngSec As Long
SngSec = Timer + NumOfSeconds
Do While Timer < SngSec
DoEvents
Loop
End Sub

Problem Statement: What are typical void fraction values at minimum fluidization in a fluidized bed within Aspen Plus? | Solution: The fluidized bed model in Aspen Plus allows to model bubbling and circulating fluidized beds. The model considers the fluid-mechanics as well as chemical reactions allowing to model for example fluidized bed reactors. One key parameter of the model is the void fraction at minimum fluidization (emf) that is used in various equations to describe the relationship between the drag force and the fluid velocity. There are basically two different approaches to estimate emf:
1. Measure the pressure drop at minimum fluidization and calculate emf using of the Ergun equation
2. Determine emf from the volume of the fixed bed and the mass of the fixed bed.
In general the value of emf depends on the particle size distribution and also the shape of the particles. Table 1 shows experimental values of emf for different particle sizes and different sphericities (ϕs). The sphericity that describes the shape of the particles is here defined as:
ϕs= (surface area of sphere of same volume as particle) / (Surface Area of particle) (1)
In most cases emf is smaller for a distribution of particle sizes compared to particles of only one size due to the fact that smaller particles will fit in the gaps between larger particles. This is fact is also evident from the figures for ‘‘rounded sand ’ϕs = 0.86’’ and ‘‘sand mixture (round particles)’’ in Table 1.

Problem Statement: Commands such as ASPCOMP and ASPLINK are not working from the Aspen Simulation Engine window. I get an error that says that the command is not found:
C:\Program Files\AspenTech\APrSystem V7.3\Engine\Xeq\asplink.bat
Error: C:\PROGRA~1\AspenTech\APrSystem is not recognized as an internal or external command. | Solution: Before Aspen Plus V8.6, Aspen Plus did not handle names with space internally. This means that special names has to be converted into short (8.3) names during the installation process. For example,
C:\Program Files\AspenTech\APrSystem V7.3\Engine
may be converted into something like
C:\PROGRA~1\AspenTech\AprSys~1.3\Engine
Note that the number after ~ can be different on different machine as the generation of short name depends on the presence of files at the time of short name generation. It seems that the user did not substitute short name for "APrSystem V7.3".
You can find short name by using commands
dir "C:\Prog*" /x
dir "C:\Program Files\AspenTech\APrS*" /x
You will see short names listed to the left of full name.
The following lines in aspsetup.bat must be converted to use short names (also do NOT use "")

Problem Statement: What is the functionality of the Aspen Production Record Manager V8 and higher when the license is unavailable? | Solution: If Aspen Production Record Manager is unable to get a license, it is either due to a license denial or the license grace period has expired.
A license denial is when the application is unable to check out a license from the license server.
A license grace period is when the license has been granted at least once, the license server cannot be contacted again, and the license timeout after 900 minutes (15 hours).
For more information, visit knowledge base article 139171.
If Aspen Production Record Manager is unable to use a license because the license’s grace period has expired or the license was denied during checkout, then the product will have a reduced or even zero functionality.
The following table shows the reduced functionality in License Grace Period and License Denied modes:

Problem Statement: When you launch Aspen Production Record Manager Administrator, the following error message appears:
"The specified service does not exist as an installed service." | Solution: This is due to Aspen Production Record Manager Services missing in the Windows Services. AspenTech recommends to completely re-install or repair the installation if services are not installed as expected.
If option to re-install is not possible, the service can be installed manually according to the instructions below:
1. Browse to C:\Windows\SysWow64.
2. Right-click on cmd.
3. Select "Run as administrator" from context menu.
4. Browse to the folder containing the executable:
cd C:\Program Files (x86)\AspenTech\Batch.21\Server
5. Create the service with the following command:
Batch21Services.exe /service DOMAIN\Username Password
6. You may need to run Batch21Services.exe /unregserver if the service is already there but appears to not work correctly.
7. If the service missing is the APRM BCU Service, the command to create the service is
BcuServer.exe /service DOMAIN\Username Password
8. You may need to run BcuServer.exe /unregserver if the service is already there but appears to not work correctly.
9. Make sure the newly created services are set to Automatic and manually start them both in Windows Services.

Problem Statement: This solution is intended for modelers who configure SCM applications for the end users.
There was a new feature introduced in V8.4 Cumulative Patch 2. Configurers/Modelers have the ability to add an icon to the tab header to communicate to the end user that this tab needs to be manually refreshed. The requirement for this type of indication has been there since the introduction of multi tabs/windows in the new GUI in V8.
Please note that there is ability within SCM to automatically refresh using the RACTREF commands - this is discussed in | Solution: # 139594.
Solution
To add the refresh icon to one tab, the following command can be used:
VMACTION ViewModelID NeedsRefresh
Where the ViewModelID is the address used to identify the View Model. For example, the Planning Board's XML configuration is stored in CPB set and the view model is CPB:PB_VM à this is the ViewModelID for the Planning Board screen. A screen's ViewModelID can also be found by using the $CURRVM command, when the screen is opened.
To refresh all the screens that are currently open, the following command can be used:
VMACTION ALL NeedsRefresh
This command can be used in Rules - so the ideal use case is if there is a Run Action command that is run and if it takes a lot of time to use the refresh the intended screens, auto refresh (RACTREF command) can be avoided and this feature can be used to indicate the users to manually hit the Refresh command.

Problem Statement: What email clients are supported in Aspen Fleet Optimizer V8.4? | Solution: For proper functioning of the eMail feature, you must install an appropriate MAPI (Mail API)-compliant eMail client on the computer where Fleet Optimizer applications are installed. MAPI includes functions that mail-enabled and mail aware programs can use to create, manipulate, transfer, and store mail messages. Microsoft Outlook is an example of a MAPI client although any MAPI SDK email client would be compatible. MAPI also contains tools that program developers can use to define the purpose and content of mail messages, and provides flexibility in the management of stored mail messages. It also provides a common interface that program developers can use to create mail-enabled and mail-aware programs independent of the underlying messaging system. Messaging clients provide an interface for interaction with the Microsoft Windows Messaging System (WMS). This interaction typically includes requesting services from MAPI-compliant providers such as message stores and address books.

Problem Statement: What is the procedure to allow an Administrator user to propagate a list of URLs to be added to the Local Intranet Zone or the Trusted Sites Zone on a system wide basis? | Solution: The IT security policies at many companies dictate that a standard non-administrator user not have permissions to edit the Internet Explorer settings. However, the Aspen PCWS web applications to view and maintain Aspen APC application requires that the web URL address be added to the Local Intranet (or Trusted Sites Zone) on the machine accessing the web page. The information listed below provides the procedure to allow an administrator user to automatically propagate a default list of URLs to the Local Intranet or the Trusted Sites zones on a machine.
1. Login to the machine/server as Administrator. Use Run command to execute gpedit.msc. This opens up the Local Group Policy Editor window.
2. From the left hand navigation pane, drill down to-
Local Computer Policy | User Configuration | Administrative Templates | Windows Components | Internet Explorer | Internet Control Panel | Security Page
3. Select Security Page from left hand pane to populate the right-hand pane.
4. On the right hand pane, double click on Site to Zones assignments list.
5. Change the setting to Enabled.
6. Under options section, click on the Show button to build up the list to allowed URLs.
7. Add the PCWS server name in the URL list (Value Name) with a value of 1 (Local Intranet Zone).
8. Click OK to accept the settings.
9. Login as a standard, non-administrator user to confirm the URL is in the Local Intranet Zone list for the user.

Problem Statement: When Static Head option is turned in Aspen Plus Dynamic, the outlet pressure of model does not match with that in Aspen Plus. How to resolve this mismatch? | Solution: This mismatch happens as Aspen Plus models cannot take static head effects into consideration while calculating outlet pressure. One way of resolving the mismatch issue is to make some changes in both Aspen Plus and Aspen Plus Dynamics:
In Aspen Plus: Add a valve model on the out let stream where pressure is calculated.
In Aspen Plus Dynamics:
1. Change the run mode to Initialization and Run the simulation.
2. Change the parameter LiquidHead to “Yes” in the Configure Form of the model.
3. Invoke the Resize Script of the Valve in the outlet stream to set it up to “Resizing” mode. Then Run the simulation.
4. Invoke the Resize Script again for the valve to set it back to “Rating” mode.
5. Change the Run mode back to Dynamics. This adjusts the valve parameters to take the additional static liquid head into account.
Please see the attached Aspen Plus and Aspen plus Dynamics files.

Problem Statement: Can we use two phase-specific (vapor and liquid) U values for Heat exchangers in Aspen Plus Dynamics? | Solution: Currently Aspen Plus Dynamics does not support two individual phase heat transfer co-efficient for heat exchanger models. The ways dynamic heat exchangers are modeled are as an inlet and outlet holdups which are connected by a "valve" that applied the heat transfer and pressure drop.
If you are just using something constant like cooling water as your coolant, you might be able to use a dynamic Flash2 block instead and under “Dynamics | Heat Transfer” set the heating to LMTD, condensing, or evaporating then set the mass flowrate of coolant and the heat capacity of the coolant.

Problem Statement: The collected data in Aspen Watch Performance Monitor/PID Watch V8.0 always displays the controller mode as Local/Manual even when it should be displaying Remote/Manual mode. | Solution: ***Note- This solution ONLY applies to applications working with a Delta V DCS.
The source of the problem is that the underlying SQL procedure used to determine the correct mode for a PID loop does not make distinction between the REMOTE/MANUAL and LOCAL/MANUAL modes.
Explanation - The following code logic is used in the SQL Procedure for interpreting the Mode for a PID Loop.
Value of AW_L8 (MODE.ACTUAL)
Bit 4 (8)
(Manual Flag)
Bit 5 (16)
(Auto Flag)
Bit 6 (32)
(Remote Flag)
AW_MODE

Currently falls through to Local/Manual
This should be changed to Remote/Manual
48
0

1
Remote/Auto
The procedure listed below can be used to alter the SQL procedure to make the distinction between the last two modes.
NOTE THAT ANY CHANGE(S) MADE TO THE SQL PROCEDURE WILL GET OVERWRITTEN WHEN YOU RUN INSTALL DATABASE CONFIGURATION.
1. Use Aspen SQLplus to open the AWP_PIDC_DELTAV.SQL procedure located in the C:\Program Data\Aspentech\APC\Performance Monitor\etc\sql\pid\ directory.
2. Scroll down the script and navigate to the section on "Begin Normal "ON" processing logic | Step 2: Process the AW_MODE | Set AW_MODE value"
3. The SQL logic for setting the AW_MODE value should be revised to recognize the Remote/Manual state. This can be done by adding script shown below (Boxed) to the code at the indicated location.
CASE
WHEN (REM_FLAG = 0 AND AUTO_FLAG = 16) THEN
PIDREC->AW_MODE = 2; -- Local/Auto
WHEN (REM_FLAG = 32 AND AUTO_FLAG = 16) THEN
PIDREC->AW_MODE = 3; -- Remote/Auto
WHEN (REM_FLAG = 32 AND AUTO_FLAG = 0) THEN
PIDREC->AW_MODE = 1; -- Remote/Manual
ELSE
PIDREC->AW_MODE = 0; -- Local/Manual
END
4. Save the changes made to the procedure using "Record->Save As" option from the menubar.

Problem Statement: When working with Aspen Process Manual and the user is browsing the manuals as well as the information content, it sometimes only shows the pictures of figures and graphs but not the equations in specific. | Solution: In order to solve this when only the equations in specific are not shown, one has to check first if the following registering file: ‘ShowEqn03.dll’, is in the AspenTech shared location.
If the installation is normal, enter at a command prompt the following:
Regsvr32 “C:\Program Files (x86)\Common Files\AspenTech Shared\ShowEqn03.dll”
One probably needs to start the command prompt as an ‘Administrator’.
After doing that, it is necessary to refresh the IIS (Internet Information Services) Manager application pool and see if it fixes the problem. In order to do that, find below the instructions:
1) Open IIS (Internet Information Services) Manager following these steps:
To start IIS Manager from the Run dialog box
1. On the Start menu, click All Programs, click Accessories, and then click Run.
2. In the Open box, type inetmgr and then click OK.
To start IIS Manager from the Administrative Services console
1. On the Start menu, click All Programs, click Accessories, and then click Run.
2. In the Run text box, type control panel, and then click OK.
3. In the Control Panel window, click Classic View, and then double-click Administrative Tools.
4. In the Administrative Tools window, double-click Internet Information Services.
2) Select ‘Application pools’.
3) Then, right clicking on the Application Pool related to ‘Aspen Process Manuals’ which is running on, select ‘Recycle…’ and check that the status remains as ‘Started’.
4) Now, the Process Manual application should work correctly.

Problem Statement: How do I generate the Mass/Energy Balance for a single unit operation? | Solution: People can see the flowsheet-wide Mass/ Energy Balance from Flowsheet summary. However, they may wonder if HYSYS can generate the Mass/ Energy Balance for a single unit operation. The answer is Yes. You can use Property Balance from Model Analysis to achieve that. We will use a crude distillation column as an example.
1. Open your process simulation and go Model Analysis> Property Balance. Then it will open Property Balance Utility
2. From Scope Objects, you can select the objects that you are looking to. In this example, T 100 column has been selected. Users can select a list of unit operations if they want.
3. From Insert Variable, you can select the variable as Mass flow and then you will be able to see the balance results.
4. The energy balance is on the next tab.

Problem Statement: If I have some hypothetical components on my simulation defined by the Oil Manager, the composition is deleted when I define the composition from the Oil & Gas Feed section. | Solution: Defining from Oil & Gas Feed and and the Oil manager are two completely different tools. The Oil & Gas Feed data calculation will erase the existing data and fill in new data if it calculates.
Once the user enters the density, the black oil calculation takes over, which overwrites the oil manager data. If the user continues to enter gas compositions, GOR and WOR, and other information, oil and gas feed will have enough information to solve and provide the user with compositions calculated by black oil. Therefore, the stream cannot have any composition defined. And the hypo components will be used to map the composition calculated by the information defined on the Oil & Gas stream tab.

Problem Statement: How to access SULSIM extension in Aspen HYSYS | Solution: SULSIM is a third party program for sulphur treatment in a gas plant that can work inside Aspen HYSYS. To be able to run this program inside HYSYS, both HYSYS and SULSIM should install on your machine. The first license is the link license and second one is SULSIM license and both are given by Aspentech these days. If somebody has old license available, still they can use the SULSIM.
To register the extension, press 'Register an Extension' button on Tools| Preferences| Extensions tab and select 'SulsimLinkExtn.dll' file to be registered. This file is usually located in C:\Program Files\AspenTech\Aspen HYSYS ( version)\Extensions\SulSim
After registering the extension, add this extension to your HYSYS pre-built case (as it does not run as a standalone version) by pressing F12 to bring the Unit Op screen up and selecting Extension radio button then SULSI,M Extension. To run it and as mentioned above, you will need to purchase the program and its license from Sulphur Experts.

Problem Statement: There might be situations when you need to change the Activity labels on the Planning Board. This solution explains how to configure this.
The prerequisite for reading this document is a basic understanding of Aspen SCM. | Solution: There is a table called PBLBCTL which controls the Activity Labeling schemes on the Planning Board.
The Rowset of this table (PBLBMOD) corresponds to the View Settings Panel | Gantt Chart Labels section | Label Above / Inside / Below Format dropdown menu.
For the corresponding entries of PBLBMOD, there is a FMTSET / Activity Labeling - Format Set entry in PBLBCTL. These FMTSETs usually start with characters “ALABFMT”. If you right click on the entry, you would be taken to the corresponding table which explains how the label is formed when that scheme is selected.
This table might contain another working table which cross references the PROs to Labels. You can make a copy of this table (using FORM and FILL command), make your changes to it and point this new table at the “ALABFMT” table, to witness the changes on the Planning Board. Make sure that you remove any rule mentioned in the PROC / Pre-processing Procedure entry for that corresponding scheme in PBLBCTL.
Sometimes, instead of a table, there may be some characters starting with an *. The following is a list of keywords and descriptions for each one of them that could be used:

Problem Statement: What is the usage of the button "Execute Excel Macro button" when running a report template from the Excel ribbon? How do I include in the created template a customized macro to be executed after the report has been generated? | Solution: The option called "Execute Excel Macro" is located in RUN REPORT dialog box populated after selecting an existing template and then selecting the RUN option from the Report Wizard ribbon.
All macros which are defined in the template would be executed after the report is generated when "Execute Excel Macro" option is selected. There is no need for any specific name.
How to create a template with macro
1. Click " New Template" to create a template according the wizard
2. Go to "Microsoft Visual Basic" (Alt-F11) and insert a module
3. Add the desired macro into the module. e.g.
4. Click ribbon button "Save Template" to save this template to your local place.
If you would like to save it to the database, you should save it to local place first, then click ribbon button "Save to Database" to save it to the database. Otherwise, the macro won't be saved to the database.
IMPORTANT:
The file format that Office 2010 suggests when trying to save the template (xltx) from the icon in the ribbon, it is not appropriate for a template containing macros. Excel will suggest that the Macro enabled template format (xltm) be used. However the procedure described above will work only if you manually select the Excel 97-2003 Template (.xlt) format which allows macros inside it.
Run template with macro
Click the ribbon button "Run Report". On the dialog, select "Execute Excel macro", then the macros which are defined in the template will be executed after the report is generated.
Some useful Excel range name defined on the report
Report Wizard creates three Excel range names for each table on the report.
1. Report generation time: The range name is [table name]_time, e.g. AspenPT1_time.
2. The left top cell of the report table: The range name is [table name]. e.g. AspenPT1.
3. The right bottom cell of the report table: The range name is [table name]_End. e.g. AspenPT1_End.
User could use these range name to search the data in the report table.

Problem Statement: I create a case 'NEW' from an existing case, for instance, 'C14' and am working in case 'NEW'. When changes come through for the case used by others 'C14', are events in 'NEW' getting changes as well? | Solution: The answer is no. When a user creates a new case (using "Add a Case" from an existing Case) any changes to the current case are saved only to the newly created case and vice versa. If other users do some changes in "C14, for instance, the NEW case should not be updated with this information.
This is because the ATOrionEvent Table has a column called ORION_CASE that stores all events for each CASE. When the user makes changes in C14, only the events related to C14 (column ORION_CASE) will be changed. Also, when users are publishing the results, the output tables that contain CASE column, such as _EVENTS,_CRDRUNS, _PL,AB_BLN_EVENTS, _RECEIPTS, _RUNS,_SERVICE__STRMS,_TANKS,_ZPL, _ZRECEIPTS, _ZRUNS, _ZSTREMS, _ZTANKS, will store results for each case.

Problem Statement: Why is the Pressure Drop not changing on the fly by or in the PFR table showed in the PFD? | Solution: The displayed pressure is not changing because it's displaying the delta P that was used in Steady State. What's recommended is to check the stream pressures or to build a spreadsheet to always calculate the DP across the PFR.
Keywords: PFR dynamic, Pressure Drop

Problem Statement: Importing Crude Events (receipts) through Excel Integration Utility (EIU):
-Crude composition (%) are not calculated properly(WCW=416.67%;FSW=83.578) | Solution: The reason for the wrong imported percentage is because the EIU Settings spreadsheet configuration
Changing the option to "Percentage(P)" will fix this issue.Now WCW=83.293% and FSW=16.70%as expected (matching with EIU Crude Receipt spreadsheet)

Problem Statement: I get the following message :
"Volume based inventories are being loaded into a weight based model."
in EIU (Excel Integration Utility) template even though:
- Only was uploading the tank weight values (WGT);
- Have set 'Validate VOL_WGT Row' to N in the Settings tab. | Solution: This kind of error could happen, for example, if your model Crude Basis is "Weight", but Process Basis is "Volume", in the CONFIG table (WGTVOL = V). EIU checks this field to identify whether it is weight/Volume basis. So this error message is by design.
Modify “Inventory Reporting” to “V” or "W" according to your model base,in the Settings worksheet (EIU) to solve this issue.

Problem Statement: How to define Event driven Step control in cyclic steady state (CSS) modeling. | Solution: We do not have an event-driven step control option in cycle organizer, when using cyclic steady state ( CSS) model. We can only specify the time driven step controls. If we want to use event-driven step controls option, then we should use gas_dynamic library model.
