ANSYS (Application)

Introduction

ANSYS http://www.ansys.com/Products 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.

Licensing

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.

The ANSYS software may only be used by permitted users. To get access submit a ticket to the sharcnet web portal and request your your username be added to the ansys group. This will give you access to ansys version 15.07 and newer. To use legacy version 14.0 request being added to the fluent group.

The SHARCNET license is purely academic and not intended for commerical use. This means results obtained from use of this software on sharcnet should be considered publishable in the spirit of the license. Therefore any non-publishable proprietary, private, commercial or contract work is strictly prohibited.

The 2014 license has been renewed. It provides 25 ansys research cfd and 256hpc seats for icemcfd, fluent and cfx. Note: The sharcnet apdl and workbench license (ie. the previous apdl, apdl-gui, runwb2 commands) was not renewed for 2014 due to low use throughout 2013 – however such functionality could be unlocked by any research group interested in paying for a license upgrade from ansys research cfd to ansys research. Submit a ticket if this is of interest and sharcnet will get a quote for the upgrade.

As of 10june2014 each user can run 4 simultaneous jobs using upto 48 hpc cores in total. Thus the following job combinations are possible when submitting jobs to the clusters: 1×52way or 2×28way or 3×20way or 4×16way.

Previous to 10Jun2014 each user could consume only 32 hpc cores simultaneously with the following job combinations: 1×36way job or 2×20way jobs or 2×16way+1x12way jobs or 4×12way jobs. Should ansys usage pick up again then the 32 hpc core limit may need to be reintroduced.

Announcements

o Jun 25, 2015: The ansys/15.0.7 cfx listing has been removed from the Availability Table for hound hence cfx for ansys/15.0.7 is currently not available on the clusters. The only current option is therefore to use cfx from ansys/14.0 or run your cfx simulation interactively within cfx-gui on vdi-centos6, viz10-uwo or viz11-uwo subject to 24hour runtime l;imit. Once cfx is working with ansys/15.0.7 or more likely with ansys/16.0 on the clusters then a mail message will be sent out to the sharcnet ANSYS mailing list.
o Nov 11, 2014: The ansys/14.0 module removed from viz8-uwo.sharcnet.ca for os upgrade.
o Oct 28, 2014: A problem running fluent (ansys/15.0.7) in the queue on hound has been found that may result in jobs running rather slowly. Therefore fluent (on hound) has been removed from the Availability Table until the problem is fixed. The fluent module remains on the cluster for debugging purposes use it at your own risk.
o Oct 2, 2014: The ansys/15.0.7 module is now available on hound, kraken, orca, redfin and saw for running upto 48cpu fluent jobs. Note that cfx currently should ONLY be used on hound as integration of cfx on remaining clusters is still being worked on. To use fluent-gui, cfx-gui or icemcfd-gui simply click the vdi-centos6 blue icon located in the Visualization Systems table found on the sharcnet systems page https://www.sharcnet.ca/my/systems to open a graphical desktop. Alternatively one can still connect directly to vdi-centos6.user.sharcnet.ca with “ssh -X” or “xming/putty” however graphical response will be comparatively slow for heavy rendering such as 3d meshes. The sharcnet license now supports Turbo-Grid 15.0 which is available within cfx-gui (along with CFX-Pre and CFX-Post as per usual). Please report any problems by opening a ticket at https://www.sharcnet.ca/my/problems/submit.
o Jun 10, 2014: The maximum hpc cores allowed per user has been increased from 32 to 48. See the above licensing section for further details. The installation of ansys 15 has been delayed but is at the top of the list for new installations.
o Jul 16, 2013: Please note that any ansys fluent-gui jobs run for more than 24 hours on the sharcnet visualization work stations and tope will be auto-terminated by the operating system.

Change Log

o Nov 2, 2014: Added ansys/14.0 onto redfin for fluent use(cfx runs but maybe slow).
o Nov 2, 2014: Added ansys/14.0 to vdi-centos6.user.sharcnet.ca, viz10-uwo.sharcnet.ca, viz11-uwo.sharcnet.ca and then removed it from viz5-uwo.sharcnet.ca and viz6-uwo.sharcnet.ca .
o Oct 28, 2014: Ansys/14.0 is no longer available on viz2-uwo, viz4-uwo, viz4-uoguelph, viz6-uoguelph or viz3-uwaterloo. Use ansys/15.0.7 on vdi-centos6 for fluent-gui, cfx-gui or icemcfd.
o Oct 2, 2014: Installed new ansys/15.0.7 on hound, kraken, orca, redfin, saw and vdi-centos6. Removed ansys/14.0 modules from smaller memory workstations viz1-wlu, viz2-wlu, viz1-wlu, viz2-wlu, viz1-uwaterloo, viz2-uwaterloo and viz5-uoguelph.
o Nov 1, 2013: Ansys 14.0 cfx removed from saw.
o Feb 4, 2013: Ansys 13.0 removed from all sharcnet systems.
o Jan 24, 2012: Ansys 14.0 is available on viz2-uoguelph and viz6-uoguelph once again.
o Apr 09, 2012: Ansys 12.1.1 has been removed from all sharcnet clusters. A copy of 12.1.1 remains on tope for users with older simulations who may still need fluent-gui or icemcfd-gui.
o Jan 06, 2012: Reinstalled ansys on mako temporarily for cfx benchmark testing
o Dec 07, 2011: Removed 13.0 from mako due to software installation disk space constraints and additionally the mako queues have a 1hour run limit and the cluster is gige only.
o Oct 28, 2011: Removed ansys 12.1.1 from mako. The ansys/13.0 module loads by default.
o Oct 25, 2011: Install ansys 13.0 on tope and sharcnet viz stations. Removed ansys 12.1 from bramble, school noting that 13.0 will replace it soon. Removed ansys 12.1 and 13.0 from guppy to avoid fluent jobs being infinitely suspended by full cluster loading by contributor jobs.
o Sep 28, 2011: Removed ansys 12.1 and installed 13.0 on silky for cfx use only.
o Aug 25, 2011: Installed ansys 13.0 on sharcnet x86_64 based centos clusters.
o Jun 2, 2011: Installed 12.1.1 on all remaining sharcnet visualization workstations.
o May 20, 2011: Installed 12.1.1 on viz1/2-wlu.sharcnet.ca workstations for testing.
o Mar 18, 2011: Removed from kraken, requin. Installed on angel, guppy, mako, orca.
