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, we provide local installations on Merlin7 which are needed mainly for some ANSYS packages, like Ansys RSM. 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 Merlin7 ANSYS

module purge
module use unstable # Optional
module search ANSYS

# Load the proper ANSYS version, in example for 2025R2
module load ANSYS/2025R2

[Example] Loading ANSYS from the Merlin7 PModules repository

🔥 [caubet_m@login001:~]# module purge
🔥 [caubet_m@login001:~]# module use unstable
🔥 [caubet_m@login001:~]# module use deprecated
🔥 [caubet_m@login001:~]# module search ANSYS
