STAR-CCM+ is a multidisciplinary engineering simulation suite to model acoustics, fluid dynamics, heat transfer, rheology, multiphase flows, particle flows, solid mechanics, reacting flows, electrochemistry, and electromagnetics. It is developed by Siemens.

License limitations

We have the authorization to host STAR-CCM+ binaries on our servers, but we don't provide licenses. You will need to have your own license in order to use this software. A remote POD license can be purchased directly from Siemens. Alternatively, a local license hosted at your institution can be used, providing it can be accessed through the firewall from the cluster where jobs are to be run.

Configuring your account

In order to configure your account to use your own license server with our Star-CCM+ module, create a license file $HOME/.licenses/starccm.lic with

File : starccm.lic

SERVER IP ANY PORT
USE_SERVER


where you change IP and PORT with the IP address and the port used by the license server at your institution.

POD license file

Researchers who have purchased a POD license from Siemens may simply configure the following $HOME/.licenses/starccm.lic file on any of our clusters where Star-CCM+ jobs are to be run.

File : starccm.lic

SERVER flex.cd-adapco.com ANY 1999
USE_SERVER


Cluster batch job submission

Select one of the available modules:

  • starccm for the double-precision flavour ie) module load starccm/19.04.007-R8,
  • starccm-mixed for the mixed-precision flavour ie) module load starccm-mixed/19.04.007

When submitting jobs on a cluster for the first time, you must set up the environment to use your license. If you are using CD-adapco's online pay-on-usage server, simply create a ~/.licenses/starccm.lic file as shown in the POD license file section above and license checkouts should immediately work. If however you are using an internal license server, then after creating ~/.licenses/starccm.lic you must submit a problem ticket to technical support so we can help co-ordinate the necessary one time network firewall changes required to access it. If you still have problems getting the licensing to work then try removing or renaming file ~/.flexlmrc since previous search paths and/or license server settings maybe stored in it which conflict with your current starccm.lic settings. Not e that files from previous may have accumulated a significant amount of disc space in hidden directories named .star-version_number if you have run many long jobs in the past using older slurm scripts or if you regularly run starccm+ in gui mode. These can be removed periodically by carefully running the command rm -rfIv ~/.starccm* where the v option will list everything that is erased.

Remote visualization

Preparation

o To set up your account for remote visualization:

  1. Create ~/.licenses/starccm.lic as described above.
  2. Users with a POD license should also
set: export LM_PROJECT='CD-ADAPCO PROJECT ID' and
add: -power to the other command line options shown below.

Compute nodes

Connect with TigerVNC and open a terminal window…

STAR-CCM+ 15.04.010 (or newer versions)
module load StdEnv/2020
module load starccm-mixed/17.02.007 **OR** starccm/17.02.007-R8
starccm+
STAR-CCM+ 14.06.010, 14.04.013, 14.02.012
module load StdEnv/2016
module load starccm-mixed/14.06.010 **OR** starccm/14.06.010-R8
starccm+
STAR-CCM+ 13.06.012 (or older versions)
module load StdEnv/2016
module load starccm-mixed/13.06.012 **OR** starccm/13.06.012-R8
starccm+ -mesa

VDI nodes

Connect to gra-vdi.alliancecan.ca with TigerVNC and login. Once the Remote Desktop appears click Applications -> Systems Tools -> Mate Terminal to open a terminal window and then specify which starccm version to load as shown below. Note that after you have loaded a StdEnv you may use the module avail starccm-mixed command to display which starccm versions are available. Note that currently only the MESA implementation of OpenGL is usable on gra-vdi with starccm due to virtualgl issues that otherwise provide local gpu hardware acceleration for OpenGL driven graphics.

STAR-CCM+ 18.04.008 (or newer versions)
module load CcEnv StdEnv/2023
module load starccm-mixed/18.04.008 **OR** starccm/18.04.008-R8
starccm+ -mesa
STAR-CCM+ 15.04.010 --> 18.02.008 (version range)
module load CcEnv StdEnv/2020
module load starccm-mixed/15.04.010 **OR** starccm/15.04.010-R8
starccm+ -mesa
STAR-CCM+ 13.06.012 (or older versions)
module load CcEnv StdEnv/2016
module load starccm-mixed/13.06.012 **OR** starccm/13.06.012-R8
starccm+ -mesa
