Problem with simulation of multistage compressor using CFX on HPC Cluster

      Hi,

      I have been trying to run a multistage compressor case setup using CFX and trying to run on HPC cluster system provided by the university. I have been running it on 6 nodes (28 cores/node). I would really like some guidance as I am stuck and unable to solve the problem.

      However, when I try to run it states the error as follows:

      Hi Akash,

      Are you able to run simulations with fewer cores?

      Hi

      No actually, I tried running with 4 nodes but it resulted in the same error and later I shifted to the 6 nodes as I thought that it might ve due to some low processing power.
