A Package for Computational Fluid Dynamics Simulations
General Information
The ANSYS software package is developed and distributed by ANSYS, Inc..
This documentation describes the specifics of installation and usage of ANSYS at HLRN. Introductory courses for ANSYS as well as courses for special topics are offered by ANSYS Inc. and their regional offices, e.g. in Germany. It is strongly recommended to take at least an introductory course (see the CAD-FEM GmbH homepage).

Example Jobscripts
Licences
Important: Add#SBATCH -L ansys
to your job script. This allows for the batch system to start the job only, when the appropriate number of licenses is available.
