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

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

To use STAR-CCM+ you need to mail support@nhr.zib.de and ask to become a member of the UNIX group adapco. We provide free Power On Demand (POD) keys for teaching and academic research for non-industry funded projects. Write use if you fullfill these conditions and state the amount of needed hours (The core/node count does not matter.).

You can check your group membership by calling groups.
In order to run STAR-CCM+ you have to specify the parameters -licpath and -podkey, as shown in the example script below.

Documentation and materials

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.

Installed versions

To see available versions type:

module avail starccm

All versions use double precision. The recommended default module - providing all necessary environment settings - can be loaded with: module load starccm

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=1999@flex.cd-adapco.com
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).

Known Issues

To check if the license server of CD-adapco is accessible type:

telnet flex.cd-adapco.com 1999

This test (Trying ...) is positiv if the server answers (within a second):
Escape character is '^]'
Typically, after some minutes, a negative test outcome is indicated by:
telnet ... Connection timed out
