Ansys is simulation software that includes several modules for modeling problems in various fields of engineering. Well-known modules include, for example, the Ansys module itself—finite element software for structural mechanics calculations—and the Fluent module, which is used for fluid flow simulation.

Please note: TheAnsysmodule is visible to everyone on the cluster. However, since Ansys is paid software, it cannot be used directly by everyone. If you wish to use Ansys, your department or institution must first apply for permission to use it. Instructions on how to do this can be found on the ZIMT website here.

ZIMT has 100 teaching licenses and 10 research licenses that may be used for teaching and research purposes. If you would like to use Ansys but your research group is not yet among the Ansys license users, please contact ZIMT Support atsupport@zimt.uni-siegen.de.

Ansys 2023R2

Only Ansys Electromagnetics is available in this version, as only this version of AnsysEM supports integration with the Slurm scheduler.

Using theansysedtgraphical user interface for project editing and job scheduling is not recommended due to slow graphics rendering. Please use AnsysEDT in batch mode with Slurm to run your prepared simulations directly on the compute nodes. Please note that a project can only be opened once; if necessary, copy the project files to separate folders to run multiple simulations concurrently.

Important: Ansys 2023R2 must use the MPI version provided by Ansys itself; to do this, specify the batch option'MPIVersion'='2021'.

Example of a job script usingansysedt:

#!/bin/bash
#SBATCH --time=0:30:00
#SBATCH --nodes=1
#SBATCH --ntasks=4
#SBATCH --cpus-per-task=4
#SBATCH --partition=short
