module load ansys/2023R2
export ANSYSLMD_LICENSE_FILE=port@host
cfx5

For production runs, create a job script:

#!/bin/bash
#SBATCH --job-name=cfx
#SBATCH --time=01:00:00
#SBATCH --mem=32G
#SBATCH --nodes=1
#SBATCH --ntasks=8

module load ansys/2023R2

cfx5solve -def simulation.def -par-local -part $SLURM_NTASKS

Note

For optimal performance, adjust the number of tasks (--ntasks) and memory (--mem) based on your simulation requirements.
