Attention

The ShARC HPC cluster was decommissioned on the 30th of November 2023 at 17:00. It is no longer possible for users to access that cluster.

Ansys EM

ANSYS Electromagnetics Suite for Linux/Unix.

Note

The University of Sheffield ANSYS licence servers currently only support ANSYS EM 2020 R1 or higher.

Caution

ANSYS users can now use a maximum of 400 concurrent cores, across all devices on campus, including personal machines and HPC clusters, and regardless of the number of ANSYS applications they have open. Please see ANSYS license restrictions for more detail.

Usage

Ansys EM can be activated using the module files:

module load apps/ansysem/16.1
module load apps/ansysem/17.2
module load apps/ansysem/18.0/binary
module load apps/ansysem/18.2/binary
module load apps/ansysem/19.0/binary
module load apps/ansysem/19.1/binary
module load apps/ansysem/19.2/binary
module load apps/ansysem/19.3/binary
module load apps/ansysem/19.4/binary
module load apps/ansysem/20.2/binary
module load apps/ansysem/21.1/binary
module load apps/ansysem/22.2/binary

Ansys EM is integrated with the Ansys Workbench GUI (the runwb2 executable) for each version. The Ansys EM exectuable is ansysedt.

Note

An accelerated-graphics interactive session with X Window support (i.e. a Hardware-accelerated graphics rendering (qsh-vis) interactive session on ShARC) is required to run the ansysedt executable as a GUI. On the login node, the command qsh-vis will initiate an accelerated-graphics interactive session.

Batch jobs

The following is an example batch submission script which is submitted to the queue by typing qsub my_job.sh:

#!/bin/bash
#$ -cwd
#$ -l h_rt=00:30:00
#$ -l rmem=2G
#$ -pe mpi 8

module load apps/ansysem/22.2

ansysedt -ng -BatchSolve -Distributed -machinelist num=8 -batchoptions 'HPCLicenseType'='pool' -useElectronicsPPE Tee.aedt

The script requests 8 cores using the MPI parallel environment mpi with a runtime of 30 mins and 2 GB of real memory per core. The Ansys EM input file is Tee.aedt and batch options 'HPCLicenseType'='pool' to change the HPC licencing from “pack” (the default) to “pool”.

Note

The University of Sheffield ANSYS licence servers currently only support ANSYS EM 2020 R1 or higher.
The -useElectronicsPPE argument is required if you are using the University of Sheffield ANSYS licence server however if you are using an alternative licencing method (e.g. a flat-file) and one of the older modules this option is unlikely to be required.
If you are using an older module the batch options may need adjusting from -batchoptions 'HPCLicenseType'='pool' to project type specific options click here and see post 4.
If you are using commercial licenses the use of -batchoptions 'HPCLicenseType'='pack' is likely compulsory.
