Running ANSYS Desktop GUI on copper

The ANSYS desktop gui can be run on the management node, but long simulations should be executed on the compute nodes. To start ANSYS workbench GUI on HPC or Copper Server

module load ANSYS
runwb2

To start FLUENT GUI, you can use : fluent instead of : runwb2 above

Submitting batch jobs through Moab

To avoid overloading the management node, ANSYS Fluent should be used in batch mode and jobs should be submitted to the compute nodes through torque.

Sample Script (UNDER DEVELOPMENT)

1. Create a job script for using 4 processors (cores) - put the following in a file called fluentjob.sh

   #!/bin/sh
#SBATCH -J JOB_NAME #Name of the computation
#SBATCH -N 1 # Total number of nodes requested
#SBATCH -n 4 # Total number of tasks per node requested
#SBATCH -t 01:00:00 # Total run time requested - 1 hour
#SBATCH -p normal # compute nodes partition requested

module load ANSYS
fluent ### OPTIONS? INPUT FILES?

2. Submit to Moab

   sbatch fluentjob.sh

3. Check status with squeue command
