Compute Canada has the authorization to host STAR-CCM+ binaries on its servers, but does not provide licenses to users. You will need to have your own license in order to use this software.
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 [https://www.plm.automation.siemens.com/global/en/buy/ 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.

In order to configure your account to use your own license server with our Star-CCM+ module, create a license file <tt>$HOME/.licenses/starccm.lic</tt> with the content :
In order to configure your account to use a license server with our Star-CCM+ module, create a license file <code>$HOME/.licenses/starccm.lic</code> with the following layout:
{{File|name=starccm.lic|contents=SERVER IP ANY PORT
{{File|name=starccm.lic|contents=SERVER <server> ANY <port>
USE_SERVER}}
USE_SERVER}}
where you change <tt>IP</tt> and <tt>PORT</tt> with the IP address and the port used by the license server.
where <code><server></code> and <code><port></code> should be changed to specify the hostname (or ip address) and the static vendor port of the license server respectively.
 
=== POD license file ===
 
Researchers with a POD license purchased from [https://www.plm.automation.siemens.com/global/en/buy/ Siemens] can specify it by creating a  <code>~/.licenses/starccm.lic</code> text file as follows:
{{File|name=starccm.lic|contents=SERVER flex.cd-adapco.com ANY 1999
USE_SERVER}}
on any cluster (except Niagara) as well as setting LM_PROJECT to your YOUR CD-ADAPCO PROJECT ID in your slurm script.  Please note that manually setting CDLMD_LICENSE_FILE="<port>@<server>" in your slurm script will no longer be required.

Select one of the available modules:
* <tt>starccm</tt> for the double-precision flavour,  
* <code>starccm</code> for the double-precision flavour (i.e., <code>module load starccm/19.04.007-R8</code>),  
* <tt>starccm-mixed</tt> for the mixed precision flavour.
* <code>starccm-mixed</code> for the mixed-precision flavour (i.e., <code>module load starccm-mixed/19.04.007</code>).


Star-CCM+ comes bundled with two different distributions of MPI:
When submitting jobs on a cluster for the first time, you must set up the environment to use your license. If you are using Siemans remote <i>pay-on-usage</i> license server then create a <code>~/.licenses/starccm.lic</code> file as shown in the <b>Configuring your account- POD license file</b> section above and license checkouts should immediately work.  If however you are using an institutional license server, then after creating your <code>~/.licenses/starccm.lic</code> file you must also submit a problem ticket to [[technical support]] so we can help co-ordinate the necessary one time network firewall changes required to access it (assuming the server has never been setup to be accessed from the Alliance cluster you will be using).  If you still have problems getting the licensing to work then try removing or renaming file <code>~/.flexlmrc</code> since previous search paths and/or license server settings maybe stored in it. Note that temporary output files from starccm jobs runs may accumulate in hidden directories named <code>~/.star-version_number</code> consuming valuable quota space.  These can be removed by periodically running <code>rm -ri ~/.starccm*</code> and replying yes when prompted.
*[https://www.ibm.com/developerworks/downloads/im/mpi/index.html IBM Platform MPI] is the default distribution, but does not work on [[Cedar]]'s Intel OmniPath network fabric;
*[https://software.intel.com/en-us/intel-mpi-library Intel MPI] is specified with option <tt>-mpi intel</tt>.  


Neither IBM Platform MPI nor Intel MPI are tightly coupled with our scheduler; you must therefore tell <tt>starccm+</tt> which hosts to use by means of a file containing the list of available hosts. To produce this file, we provide the <tt>slurm_hl2hl.py</tt> script, which will output the list of hosts when called with the option <tt>--format STAR-CCM+</tt>. 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 options <tt>--ntasks-per-node=1</tt> and <tt>--cpus-per-task=32</tt> when submitting a job.  As a special case, when submitting jobs with version 14.02.012 modules on Cedar, one must add <code>-fabric psm2</code> to the starccm+ command line (last line in the below Cedar tab of the starccm_job.sh slurm script) for multi-node jobs to run properly otherwise no output will be obtained.
== Slurm 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 [mailto:support@computecanada.ca contact us] so that we can help you setup the access to it. When all is done, your submit script should look like this, where 2 nodes are used for 1 hour; you can adjust these numbers to fit your needs.

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

Other languages:

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 a license server with our Star-CCM+ module, create a license file $HOME/.licenses/starccm.lic with the following layout:

File : starccm.lic

SERVER <server> ANY <port>
USE_SERVER


where <server> and <port> should be changed to specify the hostname (or ip address) and the static vendor port of the license server respectively.

POD license file

Researchers with a POD license purchased from Siemens can specify it by creating a ~/.licenses/starccm.lic text file as follows:

File : starccm.lic

SERVER flex.cd-adapco.com ANY 1999
USE_SERVER


on any cluster (except Niagara) as well as setting LM_PROJECT to your YOUR CD-ADAPCO PROJECT ID in your slurm script. Please note that manually setting CDLMD_LICENSE_FILE="<port>@<server>" in your slurm script will no longer be required.

Cluster batch job submission

Select one of the available modules:

  • starccm for the double-precision flavour (i.e., module load starccm/19.04.007-R8),
  • starccm-mixed for the mixed-precision flavour (i.e., 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 Siemans remote pay-on-usage license server then create a ~/.licenses/starccm.lic file as shown in the Configuring your account- POD license file section above and license checkouts should immediately work. If however you are using an institutional license server, then after creating your ~/.licenses/starccm.lic file you must also submit a problem ticket to technical support so we can help co-ordinate the necessary one time network firewall changes required to access it (assuming the server has never been setup to be accessed from the Alliance cluster you will be using). 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. Note that temporary output files from starccm jobs runs may accumulate in hidden directories named ~/.star-version_number consuming valuable quota space. These can be removed by periodically running rm -ri ~/.starccm* and replying yes when prompted.

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
