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](pmodules.md)**.

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


```bash
module purge
module use unstable # Optional
module search ANSYS

# Load the proper ANSYS version, in example for 2022R2
module load ANSYS/2025R2
```

**We strongly recommend only using ANSYS/2024R2 or superior**.
