graham: new cluster is open for testing use

ANSYS (Application)


ANSYS Fluid Dynamics software can be used to simulate a wide range of 2d or 3d fluid flow, heat and mass transfer, turbulent, reacting, and multiphase flow problems. The software can be run interactively sharcnets visualization workstations or as batch jobs via the queue on designated sharcnet clusters.


Commencing January 1, 2009, there is no cost to use ANSYS on SHARCNET clusters or SHARCNET visualization workstations. The SHARCNET policy regarding commercial software can be found here.

ANSYS on Sharcnet may only be used by permitted users. Before attempting to use ANSYS each user must submit a ticket to the sharcnet web portal and request being added to the ansys group. This will enable the necessary permissions for accessing and running the software.

The SHARCNET license was renewed for another year in January 2017 and provides a TOTAL of 25 ansys research cfd and 512 ansys hpc research seats for icemcfd, fluent, cfx and workbench, meshing use. This doubles the hpc compute capability from previous years. The apdl and mechanical licenses however were not renewed, such functionality may be unlocked if a research group or groups are willing to contribute towards upgrading the sharcnet license from ansys research cfd to ansys research in such case please open a problem ticket.

The SHARCNET license is provided free for academic research use only therefore any non-publishable. proprietary, private, commercial or contract work is strictly prohibited unless the group either provides a suitable floating license file for the sharcnet license server or permits access to a local license server.

A maximum of 3 ansys research cfd jobs maybe run per user (this limit maybe reduced to 2 if the number of active researchers increases beyond the current ~25 level) while a maximum of 96 hpc research cores maybe used per researcher for module versions >= 17.2 and 48 hpc research cores for ansys module versions <= 16.2.3 noting that 4 cores per job are not counted towards the hpc total.

o May 3 2017: Anys license usage has dropped off slightly therefore the Ansys Fluent jobs/cores limit has been (temporarily) increased from 3/96 to 5/128 on orca only. If license consumption nears 90% the limit will be immediately cut back to 4/96 or 4/128 and another message posted here.

o Feb 17 2017: The ansys/17.0 module will be removed Feb17 from all sharcnet systems. Anyone still using it should switch to ansys/17.2 before that date. Also on Feb17 ansys/17.2 will be installed on redfin. If there any concerns please open a ticket.

o Jan 23 2017: Ansys 18.0 is released! Its not installed on sharcnet yet but will be asap. Some benefits of this version follow:

 – Improved CFD workflow, geometry preparation and breakthrough harmonic analysis that accelerate your simulations for
better, more reliable CFD analysis
 – Advances in automated simulation and design workflows for workflows for antennas, high-speed electronics and electric
 – Structural lightweighting, topology optimization and PCB modeling improvements that enable you to design lighter,
stronger, more efficient products
 – A new modeling environment for simulating complete physical systems and interoperability with systems engineering
 – New solutions for developing complex, high-integrity embedded applications for avionics and advanced driver assistance
 – Advanced semiconductor process technology that accelerates development and ensures power integrity across chip, package
and system
 – Improved collaboration tool in ANSYS AIM for upfront simulation and optimization of electromagnetic devices
 – New platform enhancements including an ACT app builder and support for workflow automation APIs and vertical apps

o Jan 9 2017: Ansys/14.0 now belongs to the ansys group. Previously it was accessible only to researchers in the now obsolete fluent group.

o Sept 15 2016: The maximum number of simultaneous ansys jobs (fluent/cfx) each user can run has been increased from 2 to 3. Its recommended each user limit themself to running 2 jobs so that one license can be kept free for pre/post processing on the vdi-centos6 visualization workstation. Users may purchase and add dedicated license tokens if they need guarenteed access. Researchers residing at institutions with sharcnet hardware may look into utilizing site license token which sharcnet ansys can be configured to use – if so interested open a ticket.

o Apr 15, 2016: Ansys 16.2.3 including cfx and fluent is now installed on sharcnet. The ansys cfx/15.0.7 module is fixed on all systems. Please review the Documentation for detailed cluster specific instructions regarding how to sqsub cfx jobs, as these have changed.
