Caution: this page contains information about the OMNI cluster! The corresponding page for the HoRUS cluster can be found here.
Ansys is a simulation software that comprises multiple modules for solving problems from various engineering disciplines. Examples for common modules include the Ansys module proper, which is a Finite-Element software for structural computations, as well as the Fluent module which is used for Computational Fluid Dynamics.
Caution: The module
ansys is visible to everyone on the cluster. However, since Ansys is not free of charge, it may not be used immediately by everyone. If you would like to use Ansys, your chair or institution needs to apply for Ansys use first. The details of how to do that are described (in German) on the ZIMT website here.
ZIMT owns 100 teaching and 10 research licenses, which may be used for teaching and research purposes. If your lab wants to use Ansys but is not yet part of the licence holders, contact firstname.lastname@example.org .

Version 2021R1 provides only the Ansys Electromagnetics Suite, because of its slurm scheduler integration.
Usage of the graphical interface
ansysedt for project preparation and job submission is not recommended due to slow interaction and missing OpenGL support. We advice to use AnsysEDT in batch mode with slurm to directly run your prepared simulations on the compute nodes. Be aware that projects may be opened only one time. Use separate folders in order to run multiple simulations concurrently.
Example for a job script with ansysedt:
#!/bin/bash #SBATCH --time=0:30:00 #SBATCH --nodes=1 #SBATCH --ntasks=4 #SBATCH --cpus-per-task=4 #SBATCH --partition=short module load ansys/2021R1 ansysedt -distributed includetypes=default maxlevels=1 -machinelist num=$SLURM_NTASKS -monitor -ng -batchoptions ' '\''HFSS/NumCoresPerDistributedTask'\''=$SLURM_CPUS_PER_TASK '\''HFSS/RAMLimitPercent'\''=90' -batchsolve <projekt>.aedt
