#139 Not Reproducible COLTT log file created for a case with failed initialisation of Aspen Properties won't load into the Viewer michaelhalloran michaelhalloran

Reported by michaelhalloran, 10 years ago.

Description

This one is a mistake caused by using the Viewer when the log file was still being written to.

#141 fixed Calls to GetCompoundList by COLTT within Validate michaelhalloran michelpons

Reported by michelpons, 10 years ago.

Description

I am using PRO/II 9.2 alpha and I am starting from a case file where the CPP Ideal Thermo PPM and its PP nC6nC8 are plugged in. Then I am inserting the CPP MixerSplitter example UO, connected its two inlets and one outlet. Then I am running the case, saving and exiting. This gives the attached log file. I am puzzled by what COLTT does within the Validate call: three calls to GetCompoundList and one call to GetSinglePhasePropList. I don't see the purpose of the three successive calls to GetCompoundList.

#142 fixed Calls wrongly attributed to COLTT michaelhalloran michelpons

Reported by michelpons, 10 years ago.

Description

I am using PRO/II 9.2 alpha and I am starting from a case file where the CPP Ideal Thermo PPM and its PP nC6nC8 are plugged in. Then I am inserting the CPP MixerSplitter example UO, connected its two inlets and one outlet.

Then I am running the case, saving and exiting. This gives the attached log file. I am looking at the sequence of calls logged at the beginning of the Calculate call:

COLTT <Anonymous> : Call to GetOverallProp

GetOverallProp Takes Input arguments:

Property Basis pressure UNDEFINED

GetOverallProp Returns:

Property Basis ValueReturned pressure UNDEFINED 100000

COLTT <Anonymous> : Return from GetOverallProp - Succeeded COLTT <Anonymous> : Call to GetOverallProp

GetOverallProp Takes Input arguments:

Property Basis totalFlow mole

GetOverallProp Returns:

Property Basis ValueReturned totalFlow mole 1.25998

COLTT <Anonymous> : Return from GetOverallProp - Succeeded COLTT <Anonymous> : Call to GetOverallProp

GetOverallProp Takes Input arguments:

Property Basis fraction mole

GetOverallProp Returns:

Property Basis ValueReturned fraction mole 0.3

0.7

COLTT <Anonymous> : Return from GetOverallProp - Succeeded COLTT <Anonymous> : Call to CreateMaterial COLTT <Anonymous> : Return from CreateMaterial - Succeeded COLTT Reference count for MO logger is 2 MaterialObject <Anonymous> : Call to CopyFromMaterial

It says that COLTT retrieves pressure, totalflow and composition. Well my reading of the CPP MixerSplitter source code tells me it is the Unit Operation which does that.
