Ansys Electromagnetic Suite is a suite of software for engineering analysis for electrical and electronic products.
**************************************************** NOTE **************************************************** This is restrictively licensed software. It is currently being made available on the UMD HPC clusters by the generosity of the Dept of Mechanical Engineering.
This section lists the available versions of the package ANSYSEMon the different clusters.
| Version | Module tags | CPU(s) optimized for | GPU ready? |
|---|---|---|---|
| 23.1 | ansys-em/23.1 | x86_64 | Y |
| 21.2 | ansys-em/21.2 | x86_64 | Y |
Although generally it is preferable to do production runs in batch mode, as discussed in the next section, it is sometimes useful to invoke the Ansys EDT GUI. This is particularly useful for setting up/designing the simulation.
Running graphical applications on the HPC cluster so that the display goes
back to the workstation you are sitting at can be tricky. The easiest solution
is to use the interactive
desktop applet in the
OnDemand portal. This will start a job on the cluster which presents a full graphical desktop to you through your
web browser. You can then open a terminal window,
module load ansys-em and invoke the ansysedt to
start the GUI. Note that it can take a while (on order of 10 minutes) to
start up the first time. Once it starts up, you can design your job and
or run it on the compute node assigned to the desktop (as it is a compute
node, not a login node, you are allowed to perform computationally intensive
tasks.)
Alternatively, you can start the GUI on a login node with display sent back to an X server on your workstation. You need to have an X server running on the workstation where you are sitting (see the section on Graphics for more information). As this runs on the login nodes, you are not allowed to do anything real computations there, and memory will be restricted.
In both cases, it is assumed that you are going directly from the workstation at which you are seated to the OnDemand portal/login node. Going through another layer of remote connection can cause problems.
For production runs it is generally best to run Ansys EDT in batch mode.
This also has the benefit of allowing one to use multiple CPU cores across
multiple nodes using the Ansys RSM service. This section assumes you already
have an ansys project file (.aedt file), often created from the
GUI. You can then submit it with a
Slurm/sbatch job submission script similar to this sample script
ansys-em_job.sh.
This job script sets the environmental variable PBS_JOBID to
the Slurm job id (SLURM_JOBID) and generates an appropriate batch options file.
It then proceeds to invoke ansysedt on the MyProject.aedt project file.
You will want to adjust the walltime and number of cores/nodes/etc requested,
as well as the name of the input .aedt in the script.
