I am using ChemSep Lite in Aspen Hysys 7.2 while relying on 1.1 Thermo (a COMThermo PP here). I am logging just ChemSep UO when configuring the case. As shown in the attachment, just at the beginning of the Edit method, there seems to be a call to get_MaterialTemplate. With COLTT enabled on ChemSep UO, Aspen Hysys crashes. Without cOLTT enabled on ChemSep UO, there is no crash.

I set up a scenario in Aspen Plus 7.2 where I reload a saved case where a COUSCOUS splitter is configured with three outlets. All ports are connected to streams. During the reload of the case, the call to Disconnect on each of the UO Port fails: \"Error returned from Disconnect - 0x80040501\". I don't see COLTT attempting to call the error handling interfaces on the Port. My understanding is that a Port should implement the error handling interfaces and so could be queried for further information. I attach the log file obtained.

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.
