ANSYS

This document describes generic information of how to load and run ANSYS software in the Merlin cluster

ANSYS software in Pmodules

The ANSYS software can be loaded through PModules.

The default ANSYS versions are loaded from the central PModules repository. However, there are some known problems that can pop up when using some specific ANSYS packages in advanced mode. Due to this, and also to improve the interactive experience of the user, ANSYS has been also installed in the Merlin high performance storage and we have made it available from Pmodules.

Loading Merlin6 ANSYS

For loading the Merlin6 ANSYS software, one needs to run Pmodules v1.1.4 or newer, and then use a specific repository (called merlin) which is only available from the Merlin cluster:

module use unstable
module load Pmodules/2.0.4
module use merlin
module load ANSYS/2024R2

Once merlin is invoked, it will disable central ANSYS installations with the same version, which will be replaced by the local ones in Merlin. Releases from the central Pmodules repository which have not a local installation will remain visible. For each ANSYS release, one can identify where it is installed by searching ANSYS in PModules with the --verbose option. This will show the location of the different ANSYS releases as follows:

For ANSYS releases installed in the central repositories, the path starts with /opt/psi
For ANSYS releases installed in the Merlin6 repository (and/or overwritting the central ones), the path starts with /data/software/pmodules

ANSYS RSM

ANSYS Remote Solve Manager (RSM) is used by ANSYS Workbench to submit computational jobs to HPC clusters directly from Workbench on your desktop.

Therefore, PSI workstations with direct access to Merlin can submit jobs by using RSM.
