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.

VersionModule FileRemarks
14.02.012-R8starccm/12.04.012-r8double precision version
14.04.011-R8starccm/14.04.011-r8double precision version

The module name is starccm. Other versions may be installed. Inspect 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

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
#!/bin/bash
#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.
