# ANSYS HFSS (ElectroMagnetics)
|
|
|
|
This recipe is intended to show how to run ANSYS HFSS (ElectroMagnetics) in Slurm.
|
|
Having in mind that in general, running ANSYS HFSS means running **ANSYS Electronics Desktop**.
|
|
|
|
## Running HFSS / Electromagnetics jobs
|
|
|
|
### PModules
|
|
|
|
Is necessary to run at least ANSYS software **ANSYS/2022R1**, which is available in PModules:
|
|
|
|
```bash
|
|
module use unstable
|
|
module load Pmodules/1.1.6
|
|
module use overlay_merlin
|
|
module load ANSYS/2022R1
|
|
```
|
|
|
|
## Remote job submission: HFSS RSM and SLURM
|
|
|
|
Running jobs through Remote RSM or Slurm is the recommended way for running ANSYS HFSS.
|
|
|
|
* **HFSS RSM** can be used from ANSYS HFSS installations running on Windows workstations at PSI (as long as are in the internal PSI network).
|
|
* **Slurm** can be used when submitting directly from a Merlin login node (i.e. `sbatch` command or interactively from **ANSYS Electronics Desktop**)
|
|
|
|
### HFSS RSM (from remote workstations)
|
|
|
|
Running jobs through Remote RSM is the way for running ANSYS HFSS when submitting from an ANSYS HFSS installation on a PSI Windows workstation.
|
|
A HFSS RSM service is running on each **Merlin login node**, and the listening port depends on the ANSYS EM version. Current support ANSYS EM RSM
|
|
release and associated listening ports are the following:
|
|
|
|
<table>
|
|
<thead>
|
|
<tr>
|
|
<th scope='col' style="vertical-align:middle;text-align:center;">ANSYS version</th>
|
|
<th scope='col' style="vertical-align:middle;text-align:center;">Login nodes</th>
|
|
<th scope='col' style="vertical-align:middle;text-align:center;">Listening port</th>
|
|
</tr>
|
|
</thead>
|
|
<tbody>
|
|
<tr align="center">
|
|
<td>2022R1</td>
|
|
<td><font size="2" face="Courier New">merlin-l-001 merlin-l-001 merlin-l-001</font></td>
|
|
<td>32958</td>
|
|
</tr>
|
|
<tr align="center">
|
|
<td>2022R2</td>
|
|
<td><font size="2" face="Courier New">merlin-l-001 merlin-l-001 merlin-l-001</font></td>
|
|
<td>32959</td>
|
|
</tr>
|
|
<tr align="center">
|
|
<td>2023R2</td>
|
|
<td><font size="2" face="Courier New">merlin-l-001 merlin-l-001 merlin-l-001</font></td>
|
|
<td>32960</td>
|
|
</tr>
|
|
</tbody>
|
|
</table>
|
|
|
|
Notice that by default ANSYS EM is listening on port **`32958`**, this is the default for **ANSYS/2022R1** only.
|
|
|
|
* Workstations connecting to the Merlin ANSYS EM service must ensure that **Electronics Desktop** is connecting to the proper port.
|
|
* In the same way, the ANSYS Workstation version must be the same as the version running on Merlin.
|
|
|
|
Notice that *HFSS RSM is not the same RSM provided for other ANSYS products*.
|
|
Therefore, the configuration is different from [ANSYS
|
|
RSM](ansys-rsm.md).
|
|
|
|
To setup HFSS RSM for using it with the Merlin cluster, it must be done from the following **ANSYS Electronics Desktop** menu:
|
|
|
|
1. **[Tools]->[Job Management]->[Select Scheduler]**:
|
|
|
|
|
|
|
|
2. In the new **[Select scheduler]** window, setup the following settings and **Refresh**:
|
|
|
|
|
|
|
|
* **Select Scheduler**: `Remote RSM`.
|
|
* **Server**: Add a Merlin login node.
|
|
* **User name**: Add your Merlin username.
|
|
* **Password**: Add you Merlin username password.
|
|
|
|
Once *refreshed*, the **Scheduler info** box must provide **Slurm**
|
|
information of the server (see above picture). If the box contains that
|
|
information, then you can save changes (`OK` button).
|
|
|
|
3. **[Tools]->[Job Management]->[Submit Job...]**:
|
|
|
|
|
|
|
|
4. In the new **[Submite Job]** window, you must specify the location of the **ANSYS Electronics Desktop** binary:
|
|
|
|
|
|
|
|
* In example, for **ANSYS/2022R1**, the location is `/data/software/pmodules/Tools/ANSYS/2021R1/v211/AnsysEM21.1/Linux64/ansysedt.exe`.
|
|
|
|
### HFSS Slurm (from login node only)
|
|
|
|
Running jobs through Slurm from **ANSYS Electronics Desktop** is the way for
|
|
running ANSYS HFSS when submitting from an ANSYS HFSS installation in a Merlin
|
|
login node. **ANSYS Electronics Desktop** usually needs to be run from the
|
|
**[Merlin NoMachine](../how-to-use-merlin/nomachine.md)** service, which currently runs
|
|
on:
|
|
|
|
* `merlin-l-001.psi.ch`
|
|
* `merlin-l-002.psi.ch`
|
|
|
|
Since the Slurm client is present in the login node (where **ANSYS Electronics
|
|
Desktop** is running), the application will be able to detect and to submit
|
|
directly to Slurm. Therefore, we only have to configure **ANSYS Electronics
|
|
Desktop** to submit to Slurm. This can set as follows:
|
|
|
|
1. **[Tools]->[Job Management]->[Select Scheduler]**:
|
|
|
|
|
|
|
|
2. In the new **[Select scheduler]** window, setup the following settings and **Refresh**:
|
|
|
|
|
|
|
|
* **Select Scheduler**: `Slurm`.
|
|
* **Server**: must point to `localhost`.
|
|
* **User name**: must be empty.
|
|
* **Password**: must be empty.
|
|
|
|
The **Server, User name** and **Password** boxes can't be modified, but if
|
|
value do not match with the above settings, they should be changed by
|
|
selecting another Scheduler which allows editig these boxes (i.e. **RSM
|
|
Remote**).
|
|
|
|
Once *refreshed*, the **Scheduler info** box must provide **Slurm**
|
|
information of the server (see above picture). If the box contains that
|
|
information, then you can save changes (`OK` button).
