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[edit]

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[edit]

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[edit]

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[edit]

Select one of the available modules:

  • starccm for the double-precision flavour,
  • starccm-mixed for the mixed-precision flavour.

Star-CCM+ comes bundled with two different distributions of MPI:

  • IBM Platform MPI is the default distribution, but does not work on Cedar's Intel OmniPath network fabric;
  • Intel MPI is specified with option -mpi intel.

Neither IBM MPI nor Intel MPI are tightly coupled with our scheduler; you must therefore tell starccm+ which hosts to use by means of a file containing the list of available hosts. To produce this file, we provide the slurm_hl2hl.py script, which will output the list of hosts when called with the option --format STAR-CCM+. This list can then be written to a file and read by Star-CCM+. Also, because these distributions of MPI are not tightly integrated with our scheduler, you should use option --ntasks-per-node=1 and set --cpus-per-task to use all cores as shown in the scripts.

You will also need to set up your job environment to use your license. If you are using CD-adapco's online pay-on-usage server, the configuration is rather simple. If you are using an internal license server, please contact us so that we can help you set up the access to it.

Note that at Niagara, the compute nodes mount the $HOME filesystem as read-only. Therefore it is important to define the environment variable $STARCCM_TMP and point it to a location on $SCRATCH, which is unique to the version of StarCCM+. Otherwise, StarCCM+ will try to create such a directory in $HOME and crash in the process.

Remote visualization[edit]

Preparation[edit]

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
