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).


The following tables lists installed STAR-CCM+ versions.

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

All usage of STAR-CCM+ products at HLRN is strictly limited to teaching and academic research for non-industry funded projects only.

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.

To use STAR-CCM+ you need to mail support[at]hlrn.de and ask to become a member of the UNIX group adapco. In the same email you may apply for a Power On Demand (POD) license key by stating the estimated amount of wallclock time.

You can check your group membership by calling groups.

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.

Example Jobscripts

This is an example for a parallel job
#SBATCH -t 00:10:00
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=40
#SBATCH -p medium
#SBATCH --mail-type=ALL
#SBATCH --job-name=StarCCM

module load starccm/14.04.011-r8

## 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.
