A Package for Computational Fluid Dynamics Simulations
General Information
Producer: Siemens PLM Software (formerly CD-adapco Group)
This documentation describes the specifics of installation and usage of STAR-CCM+ at HLRN. Introductory courses for STAR-CCM+ as well as courses for special topics are offered by CD-adapco and their regional offices, e.g. in Germany. It is strongly recommended to take at least an introductory course (please contact Siemens PLM Software).
Modules
The following tables lists installed STAR-CCM+ versions.
| Version | Module File | Remarks |
|---|---|---|
| 14.02.012-R8 | starccm/12.04.012-r8 | double precision version |
| 14.04.011-R8 | starccm/14.04.011-r8 | double precision version |
Other versions may be installed. Please check the output of module avail starccm.
Functionality
STAR-CCM+ is a powerful finite-volume-based program package for modelling of fluid flow problems. (The name STAR stands for "Simulation of Turbulent flow in Arbitrary Regions".) The STAR-CCM+ package can be applied to a wide range of problems such as
- Aerospace Engineering
- Turbomachinery
- Chemical Process Engineering
- Automotive Engineering
- Building and Environment Engineering
Conditions for Usage and Licensing at HLRN
All usage of STAR-CCM+ products at HLRN is strictly limited to teaching and academic research for non-industry funded projects only.
Currently, STAR-CCM+ Power On Demand (POD) license is available for users in Emmy System (HLRN-IV in Göttingen). To obtain the POD license key, interested users must apply by sending an email to support@hlrn.de stating their HLRN user account and estimated amount of wallclock time for their projects.
In order to run STAR-CCM+ on HLRN-IV, you have to specify the parameters -licpath and -podkey, as shown in the example script below. Users with their own licenses can specify the parameters to point to their own licenses.
Access to the binary code is given to users who are members of the UNIX group adapco. Users can request to become a member of this group by contacting their local HLRN project consultant.
Details of the HLRN Installation of STAR-CCM+
STAR-CCM+ is installed below /sw/eng/starccm/. We provide module files which make all environment settings for the use of a specific STAR-CCM+ version.
STAR-CCM+ products come with complete documentation. The User Guide is available in PDF format, see directory /sw/eng/starccm/<version>/STAR-CCM+<version>/doc.

## create the host list for starccm+
srun hostname -s | sort | uniq -c | awk '{ print $2":"$1 }' > starhosts.${SLURM_JOB_ID}
export CDLMD_LICENSE_FILE=<port@licenseserver>
export PODKEY=<type your podkey here>
export MYCASE=<type your sim file name>
## run starccm+
starccm+ -dp -np ${SLURM_NTASKS} -batch ${MYCASE} \
-power -podkey ${PODKEY} -licpath ${CDLMD_LICENSE_FILE} \
-machinefile starhosts.${SLURM_JOB_ID} -mpi intel
echo '#################### StarCCM+ finished ############'
rm starhosts.$SLURM_JOB_ID
Despite the fact that -machinefile starhosts.$SLURM_JOB_ID is used, you have to specify the number of worker processes (-np).
Tutorial Cases for STAR-CCM+
Tutorial case files can be found in /sw/eng/starccm/<version>/STAR-CCM+<version>/doc/startutorialsdata resp. (with solutions) in /sw/eng/starccm/<version>/STAR-CCM+<version>/tutorials, verification data in /sw/eng/starccm/<version>/STAR-CCM+<version>/VerificationData.
