Running Ansys CFX

You can run CFX solve jobs in a Fluids Slurm cluster setup in the following ways:

Run the CFX Solver Manager interactively with Slurm and use cluster nodes
Run CFX with Slurm in Batch Mode Using the Command line
Run CFX in Batch Mode Using a Slurm Script

Note: To run a larger case on a large number of nodes with AMD processors, you should submit the job using a Slurm script that includes the following argument: export I_MPI_OFI_PROVIDER=psm3. Otherwise, the solution may hang.

This argument cannot be specified using the command line or Solver Manager. It does not work for Intel nodes.
