DWSIM 5.2 Update 10: Same error message as before (see attached screenshot).
[edit: screenshot updated]

Hi, I try to solve my unit operation in DWSIM and get an error message when calling 'SetOverallProp' on the material object. My problem is that the particular code in the unit operation is generated by AmsterCHEM's COM CAPE-OPEN Wizard (C++) and the socket is part of DWSIM (vb). The same unit operat...

This discussion continued in the DWSIM forum (https://sourceforge.net/p/dwsim/discussion/844528/thread/3682f2f1/). Here are my conclusions: In the DWSIM socket we have/had 1) Validate() 2) RestorePorts() -> this invalidates the unit operation, because the "portConnectionChanged" event is f...

Hi Daniel, I have a request regarding calling 'validate' and 'calculate' of CAPE-OPEN unit operations in DWSIM. My ScaledMixerSplitter CAPE-OPEN unit operation already runs in COFE 3.2 and Aspen Plus v9, but unfortunately not yet in DWSIM. The problem seems to be that the unit operation is somehow r...

Hi Jasper, I added a scilab unit operation to a flowsheet. This unit only has one port: An output. When I call "getSinglePhaseProperty" to get the activity coefficient e1_greek_gamma_i = getSinglePhaseProperty("activityCoefficient","liquid",e1_T,e1_p,e1_x_i); I get the ...

DWSIM 4.2 (Update 3) When I drag&drop a "CAPE-OPEN Unit Operation" from the "Custom Blocks" frame into the flowsheet, the "Add CAPE-OPEN Unit Operation" dialog pops up, giving the options to 1) select a detected CO-UO and press OK or 2) press Cancel Problem: When I ...

Great, now it works! My main problem was the missing "CheckArray" call. Without that, the count was not initialized and GetCount() always returned 0. Here comes the corrected code snippet for the interested reader: CBStrConst bstrPressure(L"pressure"); wstring error; COMSmartPtr<...

I corrected the special property argument in my code. So far, I thought temperature, flow and pressure are quite common properties. That's why I set that special parameter to 'false' ;-) The other reason: I use COCO/COFE for testing and expected it to use "Material11". There the 'special p...

Hello again, I used the COM CAPE-OPEN Wizard 2.0 to generate a unit operation framework. Classes for parameters, ports, material etc. are therefore automatically generated. 1. There is a typo in the "material" classes: It reads "Propery" instead of "Property", e.g. &quo...

Some basic question regarding the COMSmartPtr and the access of collection elements: //This is given (created by the COM CO Wizard 2.0) Collection<Parameter,true> parameterCollection; //Now I want to access elements of this collection: //This gives no error, but I need a RealParameter COMSmartPtr<Pa...
