Fluent Cluster Problems

ethanw · April 15, 2022, 13:41

My university has recently upgraded its cluster computer. I have updated the batch script accordingly however I am now getting the following error which I have never seen before.

Unable to determine machine architecture.
Set the environment variable FLUENT_ARCH and try again.

I am not aware of setting any environment variable within my batch script or input file. Does anyone know how to fix this?

Have you looked at this from the ANSYS Community forum :

Perhaps you are loading the wrong file to launch the application.

No, I had not seen that before but that seems to have fixed the problem. The path to fluent had changed and I was not aware.

Thanks for your help.
