On the 21st of October 2021 we will be deploying multi-factor authentication on the HPC login nodes (ShARC & Bessemer) for all password logins.

For more information please see our page on this change.


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.

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 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".
