CAPE-OPEN

I am using COCO version 3.2.03 and have recently encountered some issues. Some simulations that were previously saved under 2.7 are taking a lot longer to solve. When I try to stop the simulation by clicking on STOP, I do get the dialog box asking if I want to keep the results and I click on yes. However, the simulation will not stop. When I try to close the simulation I do get the message "Cannot close document while document is solving". I end up going into Task Manager to stop the program.

Is there any way I can investigate?

I reran the simulation, then clicked on the STOP and waited. It took about 5 minutes before I got the User abort dialog box. So that function does work.

The simulation cannot be stopped when as long as a unit operation is in control. There is a mechanism for unit operations to check whether the PME wants to abort, but not all unit operations support that.

Do you know which unit operation takes 5 minutes to calculate?
