ANSYS
Guidance last updated: 19 October 2026
The ANSYS suite of programs can be used to numerically simulate a large variety of structural and fluid dynamics problems found in many engineering, physics, medical, aeronautics and automotive industry applications.
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.

ANSYS training and help resources
Important
Academic support requests should be directed to the IT Services’ Research and Innovation team or the Ansys academic support resources (ensure you register with your University email for priority support).
ANSYS provides numerous academic training and help resources including tutorials, video lectures and examples. A short list of these resources is summarised below:
Free online Ansys Innovation Courses in fluids engineering cover CFD theory and simulation.
The ANSYS How to Videos channel has many in depth tutorials for many ANSYS products.
Those with an Ansys Learning Hub Subscription can also access further courses at the ANSYS Learning Hub courses index.
ANSYS example models
Example models and tutorial inputs are distributed separately for individual Ansys products. Use the resources for the relevant product and choose inputs matching the version you are using. See the Fluent, Mechanical / MAPDL and LS-DYNA pages for product-specific guidance.
Installation notes
Warning
MAPDL can crash in an OpenMP library under Slurm on undersubscribed nodes.
Set export KMP_AFFINITY=disabled before launching MAPDL, as described in
Ansys’s troubleshooting guidance.
The installed anssh.ini disables affinity for AMD CPUs, but can use
norespect for the Intel MPI master process when this variable is unset.
ANSYS was installed using Easybuild, build details can be found in $EBROOTANSYS/easybuild with a given module loaded.
