Three log files created for one run

[michelpons]

Usually, whatever the number of PMCs on which logging is enabled, there is a single log file created per PME run. I have a scenario that leads to three different logs created for a single PME run. The scenario is using Aspen Hysys 8.4 CP1 with Hotfix dated February 2014. Prior to running Aspen Hysys, an XFlow file has been created using the XFlowSaver UO. The attached Stream01 file is containing the saved material stream. The point here is to save a material stream created in one PME, here COFE, and to automaticalmy load this material stream in another PME. I enable COLTT on both the TEA Thermo System and on the XFlowLodaer UO. In Aspen Hysys I start with a new case. First I define a Fluid Package as a CAPE-OPEN 1.0 Property Package which is the n-depropanizer PP from TEA Thermo System. Then I insert the XFlowLoader UO in Aspen Hysys (while in hold mode) and one Material Stream. I connect this Material Stream to the outlet Port of the XFlowLoader UO. I edit the XFlowLoader and I point to the attached Stream01 file so that it may be loaded as needed. After editing, I make the flowsheet active. Then the XFlowLoader is calculated, meaning that the contents of the Stream01 file are loaded in the UO which then sets its properties in the Aspen Hysys Material Stream. I then exit Aspen Hysys without saving the case. I obtain the three attached logs. There should be only one log file.

Michel,

Can you set this case up again and use Task Manager to check how many HYSYS processes are actually running when you have all three CO PMCs instantiated? It looks to me like HYSYS is forcing CAPE-OPEN components to run out-of-process - that change might explain why there have been problems with HYSYS and it would explain why you get three logs, one per PMC process.

The first log file (the smallest one), is created when the list of CAPE-OPEN Thermo Systems and Property Packages is displayed by Aspen Hysys following the selection of CAPE-OPEN 1.0 for liquid phase. Once the selection of a given PP has been done, the second log file (which begins by a ResolvePropertyPackage call) is created. There is still one single AspenHysys.exe process active. Then I move to the Flowsheet View and I ask for inserting a CAPE-OPEN 1.0 Unit Operation. Then I select from the list provided by Aspen Hysys and I choose the XFlowLoader. It is then that the 3rd log file is created. But there is still only one AspenHysys.exe process active.
