I am using gPROMS to call an Aspen Properties Property Package. At some point gPROMS is requesting from Aspen Properties the calculation of vapor pressure for each pure compound. It gives the following sequence of calls:

PropertyPackage <Anonymous> : Call to CalcProp requesting: MaterialObject <Anonymous> : Call to get_ComponentIds

get_ComponentIds returns : WATER ETOH MEOH

MaterialObject <Anonymous> : Return from get_ComponentIds - Succeeded

Property Phase Calc Compounds vaporpressure liquid pure WATER

ETOH MEOH

MaterialObject <Anonymous> : Logging for ICOMaterialObject with GUID {3C860BB3-8AF4-4D93-A4BB-F9D068804365} is not supported by COLTT MaterialObject <Anonymous> : Call to GetNumComponents MaterialObject GetNumComponents returns 3 MaterialObject <Anonymous> : Return from GetNumComponents - Succeeded MaterialObject <Anonymous> : Call to get_ComponentIds

get_ComponentIds returns : WATER ETOH MEOH

MaterialObject <Anonymous> : Return from get_ComponentIds - Succeeded MaterialObject <Anonymous> : Call to GetProp

Warning - compIds argument is empty Property Phase Basis Calc Value returned temperature Overall (null) mixture 353.15

MaterialObject <Anonymous> : Return from GetProp - Succeeded MaterialObject <Anonymous> : Call to SetProp :

Warning - compIds argument is empty

COLTT <Anonymous> : Call to get_ComponentIds

get_ComponentIds returns : WATER ETOH MEOH

COLTT <Anonymous> : Return from get_ComponentIds - Succeeded

Property Phase Basis Calc Compounds New values vaporpressure Liquid (null) pure WATER 47368.360944

ETOH 108253.051078 MEOH 180667.040063

MaterialObject <Anonymous> : Return from SetProp - Succeeded PropertyPackage <Anonymous> : Return from CalcProp – Succeeded

One of the calls to get_ComponentIds is logged as made by COLTT but there are two other calls to get_ComponentIds in this sequence and they appear as made by the Property Package while there is only one made. So one call, while made by COLTT, is not flagged as made by COLTT.

I am using COLTT 2.1 Build June 16, 2012 enabled on Aspen Properties v7.2 in COFE. I start from the attached bkp file which, once launched in Aspen Plus, permits the creation of a CAPE-OPEN Property package. Then I launch COFE, selects Aspen Properties Thermo System and then the EtOHWater PP just created. Next I am using the \"calculator\" within the \"Flowsheet\" menu of COFE. I choose to calculate a property, density for phase \"overall\". I get a crash that I investigate with COLTT. What does not seem right to me with COLTT is the warning message appearing with the call to CalcEquilibrium. It says \"Warning - props argument is empty\". I don't see the purpose of such a warning since it is usual to have no property requested on a CalcEquilibrium call. This warning should not be there.

I am using DWSIM in which the CAPE-OPEN C++ Sample mixer is connected to two inlet streams and one outlet stream. I am just opening the case then clicking on the icon representing the UO, then exiting from DWSIM WITHOUT saving the file when asked by DWSIM. It gives a rather short log file where the most surprising point is that, at the end of it, one sees a call by COLTT on IPersistStream.Save while there is no such call made by the PME on the UO. I wonder why such a call is made and succeeds.
