#75 worksforme Aspen Hysys crashes when using logged Aspen Properties PP michaelhalloran michelpons

Reported by michelpons, 12 years ago.

Description

I am using a simple Aspen Properties PP in Aspen Hysys. Without COLTT enabled on Aspen Properties Therrmo System, I see no problem. When enabling COLTT on Aspen Properties Thermo System, I have a crash just after selecting the PP from Aspen Properties Thermo System. In the attached log, I see:

MaterialObject <Anonymous> : Call to SetProp :

Property PhaseFraction Vapor mole (null) -179769313486231570000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.000000000

which may be wrong but does not cause a crash without COLTT.

#77 fixed Viewer can't read log files michaelhalloran michelpons

Reported by michelpons, 12 years ago.

Description

Using the same .NET Unit provided by CERE, using the same scenario in COFE and in Aspen Plus 7.2, that is drop the UO onto a flowsheet made of two streams, one defined, one undefined, then connect stream 1 to inlet port and stream 3 to outlet port, then exit, I get log files which are not readable by Viewer. Viewer says there is a problem reading both files and the window remains completely blank.

#78 fixed When UO logged no connection on ports michaelhalloran michelpons

Reported by michelpons, 12 years ago.

Description

The PME used is Aspen Plus 7.2. The PMC used is a UO in .NET made by DTU/CERE. The scenario is to start from a Aspen Plus case where two streams are defined, one to serve as input, the other as output. Without COLTT enabled on the UO, it is possible to connect the defined stream to the UO inlet and to connect the other stream to the outlet port. The UO is then considered as valid and calculation may be launched. Calculation ends up with an error: the material flow in the outlet stream is way too large compared to the material flow in the inlet stream. That calls for a look with COLTT. When COLTT is enabled on the UO, it is impossible to connect streams to ports, so it is impossible to reach the point where the calculation is made.
