General computational fluid dynamics solver (cell-centered FVM)
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 recommended to take at least an introductory course (see the CAD-FEM GmbH homepage). Good (free) starting points for self-study are https://students.cadfem.net/de/ansys-gratis-lernen.html and https://courses.ansys.com

Please note the license conditions: Our academic licenses are restricted to students, PhD students, teachers and trainers of public institutions. They cannot be used in projects that are financed by industrial partners.
Important: Always add
#SBATCH -L ansys
to your job script.
The flag "#SBATCH -L ansys" ensures that the scheduler starts jobs only, when licenses are available.
You can check the availability yourself: scontrol show lic
aa_ris a "ANSYS Academic Research License" with 4 inclusive tasks. Research jobs with more than 4 tasks cost additional "
aa_t_ais a "ANSYS Academic Teaching License" with a maximum of 4 tasks. These may be used only for student projects, student instruction and student demonstrations. Eligible users are allowed to activate these, by adding the flag
to the Ansys executable.
Your job can be offloaded if parallel/gpgpu/show denotes the selected devices with a "(*)".
Your job was offloaded successfully if the actual call of you solver prints "AMG on GPGPU".
In this case, your .trn output file contains device_list and amgx_and_runtime, respectively.
Ansys only supports certain GPU vendors/models:
Look here for the PDF called "Graphics Cards Tested" of your version... (most Nividia, some AMD)
-gpgpu must be an integer multiple of the tasks per node (ntasks-per-node)
