Question Regestry Exception when running batch commands of CFX simulations

I am working with ansys to do large batches of runs using CFX through Workbench on a super computer as a graduate student.

In order to accomplish this I am using scripts written in iron python through the command line to run simulations in batch mode via the syntax

runwb2 -R script.wbjn -B

In the past this system was effective but recently I have been reviving an error when I run batches that are too large. This error is caused by tripping an exception.


This error only occurs when I am running many simulations simultaneously, typically around 48. And it typically only occurs in some of them allowing the others to proceed normally, though it can occur in all of them. It is not totally consistent.

From my attempts to research this problem online I have learned that it may have to do with licensing as well as the v130 <-- where 130 can be other numbers apparently file in the Ansys folder normally located in the appdata folder of windows, the super computer runs lynix though so I cant find that folder.

Are there any ideas on what I should look into to further diagnose the problem?

Thanks and have a nice day.

If licensing was a problem I would expect it to report licensing errors.

I never use workbench from the command line. It does not surprise me if you find that it is not very stable in your extreme case. I find the CFX command line is very good and stable - so if you can run CFX stand alone in your application I think you will find that much more stable.
Note: I do not answer CFD questions by PM. CFD questions should be posted on the forum.
