Cluster error: Fatal error in one of the compute processes
 

Hi,

I'm running my jobs in a cluster and this is not the first time, that, after some time steps, without any error, this message appears:


===============Message from the Cortex Process================================

Fatal error in one of the computing processes.

================================================== ============================

Usually after the time-step convergence.
There are other log files (fluent-error.log), where it is possible to find more information that I don't understand, as:

There is anyone that knows how to solve this?

Thanks for your help.

Did you find a solution for this problem? I have exactly the same problem (also on a cluster after simulating for some time, using ANSYS FLUENT 2022R2).
