SERVICE RISK: The Bessemer HPC cluster will be at risk from 9am on July 15th until 5pm on July 19th 2024

For further detail, please click this link.


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.


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.

Module loading

After connecting to Bessemer (see Establishing a SSH connection), you can start an interactive graphical session or submit a batch job using ANSYS programs activating them and making them available with one of the module load commands below:

module load ANSYS/19.4
module load ANSYS/20.1/binary
module load ANSYS/20.2/binary
module load ANSYS/21.1/binary
module load ANSYS/21.2/binary

and the workbench is launched using:


Fluent, CFX, ICEM, Mechanical APDL/model (and many more) can all be accessed from the workbench. Outside the workbench the corresponding GUIs can be launched using fluent, cfx5pre, icemcfd and launcher.

ANSYS Programs

As the ANSYS suite contains a large number of packages, links to each dedicated page for each ANSYS sub-package, can be found below:

ANSYS training and help resources


Academic support requests should be directed to the IT Services’ Research and Innovation team or the ANSYS Learning Forum (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:

ANSYS example models

ANSYS contains a large number of example models which can be used to become familiar with the software. The models can be found in:


Installation note for Administrators:

export FLUENT_AFFINITY=0 has been added to the module files in order to fix incorrect core allocation - see details.

mapdl will not run without modifying the file:


The following instruction should be inserted at line 2433 in anssh.ini:

setenv KMP_AFFINITY compact

Please note ANSYS 20.1 and higher versions have been installed manually with the GUI in the following directories and permissions corrected as follows:

chmod 775 -R /usr/local/packages/live/noeb/ANSYS/20.1/binary/
chmod 775 -R /usr/local/packages/live/noeb/ANSYS/20.2/binary/
chmod 775 -R /usr/local/packages/live/noeb/ANSYS/21.1/binary/
chmod 775 -R /usr/local/packages/live/noeb/ANSYS/21.2/binary/

Please follow the same install directory structure.

In addition the following software packages are not included with the installations for ANSYS 19.4:

"ANSYS Chemkin"
"ANSYS Geometry Interfaces".
