Running ANSYS Desktop GUI

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

module load ansys
runwb2

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

To start ANSYS/FLUENT GUI on Copper Server

export PATH=/opt/ansys_inc/v192/ansys/bin:/opt/ansys_inc/v192/fluent/bin:/opt/ansys_inc/v192/Framework/bin/Linux64/:$PATH

For ANSYS work bench

runwb2

For FLUENT GUI:

fluent

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
PBS -l nodes=1:ppn=4
#PBS -j oe
#PBS -N Fluent_test
#PBS -S /bin/bash
#PBS -l walltime=02:00:00

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

2. Submit to Moab

   msub fluentjob.sh

3. Check status with showq or qstat.
