This page describes how to run the Ansys GUI through Pawsey's remote visualisation service, FastX.  This will get you a dedicated node with large memory and hardware accelerated graphics. 

Prerequisites

To run interactive graphical interfaces of Ansys software you need to be familiar with these pages:

Steps

You will get an xterm from FastX. Make sure to start by setting up Ansys licensing.

Terminal 1. Ansys license environment variables
$ export ANSYSLI_SERVERS=2325@myflexlmserver.edu.au
$ export ANSYSLMD_LICENSE_FILE=1055@myflexlmserver.edu.au

Load the correct module and unset SLURM_GTIDS and make sure you use hardware accelerated graphics, by using virtualgl.

Terminal 2. Module commands
# ansys mechanical is a module in ansys-structure package, and workbench is used to stage simulation
$ module load ansys-structures/version
$ module load virtualgl
$ unset SLURM_GTIDS
$ vglrun runwb2
