I am trying to start Fluent 2023 R2 Meshing with 36 cores. Processor is AMD Ryzen Threadripper PRO 7995WX.


I get the following error:

I also tried starting fluent with the following commands

-mpi=openmpi

-mpi=intel2018

But it is the same error.

I tried Ansys Fluent 2023 R1, and it is working normally. I also tried launching Ansys Fluent 2023 R2 with 1 core, and it is working normally too; The output is the following:
