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](/merlin7/using-modules.html)**.
|
||||
|
||||
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
|
||||
|
||||
For loading the Merlin7 ANSYS software, one needs to run Pmodules v1.1.22 or newer, and then use a specific repository
|
||||
(called **`merlin`**) which is **only available from the Merlin7 cluster**:
|
||||
|
||||
```bash
|
||||
module purge
|
||||
module load Pmodules/1.1.22
|
||||
module use merlin
|
||||
module use unstable
|
||||
module use /etc/cscs-modules/
|
||||
module load cray
|
||||
module search ANSYS
|
||||
|
||||
# Load the proper ANSYS version, in example for 2022R2
|
||||
module load ANSYS/2022R2
|
||||
```
|
||||
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 Merlin7 repository (and/or overwritting the central ones), the path starts with `/data/software/pmodules`
|
||||
|
||||
**We strongly recommend only using ANSYS/2022R2 or superior**.

### 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.
|
||||
|
||||
For further information, please visit the **[ANSYS RSM](/merlin7/ansys-rsm.html)** section.
