The CHPC has an installation of Ansys-CFD along with a limited license for academic use only. The license covers use of the Fluent and CFX solvers, as well as the IcemCFD meshing code.

If you are a full time student or staff at an academic institution then you may request access to use Ansys-CFD on the CHPC clusters. Send your request along with motivation and description of the work in an email to 'helpdesk@chpc.ac.za'.

Fluent version 14.5.7 is installed in '/opt/gridware/applications/ANSYS/ansys_inc/v145/fluent'. There is also a slightly older version 14.5 which is installed in '/opt/gridware/applications/ANSYS/Fluent'. Ansys CFX and IcemCFD are installed under '/opt/gridware/applications/ANSYS/ansys_inc/v145'.

Version 15.0 editions of the Ansys software are installed under '/opt/gridware/applications/ANSYS/ansys_inc/v150'.

CHPC has academic licenses for AnsysCFD. There are 5 “solver” processes, available as aa_r_cfd and 500 “HPC” licenses, available as aa_r_hpc. There is a license resource management system. If you request license resources (as in these example scripts), the scheduler will check for license availability before starting a job. License unavailability will result in the job being held back until the necessary licenses have become available. Although use of the license resource request is not mandatory, its use is strongly recommended. If you do not use the license resource requests, the job will fail if no licenses are available. A single aa_r_cfd license is required to start the solver, and includes up to 4 HPC licenses. Therefore you should request ($nproc-4) aa_r_hpc licenses.
