STAR-CCM+

STAR-CCM+ is a complete multi-disciplinary platform for the simulation of products and designs operating under real-world conditions.

STAR-CCM+ is available as a module on Apocrita.

Usage

To run the default version of STAR-CCM+, simply load the starccm module:

module load starccm

For usage documentation, run starccm+ -help

Example jobs

Choosing the correct pe

Please note the instructions regarding choosing the correct pe for single-node and multi-node jobs.

When running jobs, replace SIM-FILE in the examples below with the name of your simulation file.

One node or less

Here is an example job running on 4 cores and 16G of ram on a single node.

SMP Process Forking

If the I_MPI_HYDRA_BOOTSTRAP environment variable is not set, the job will fail with error message: execution daemon on host HOST didn't accept task.

#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe smp 4
#$ -l h_rt=1:0:0
#$ -l h_vmem=4G

module load starccm
export I_MPI_HYDRA_BOOTSTRAP=fork
starccm+ -batchsystem sge -mpidriver intel -batch SIM-FILE

Multi-node job

Here is an example of a multi-node job running on 48 cores and utilising the sdv-i infiniband island.

#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe parallel 48
#$ -l infiniband=sdv-i
#$ -l h_rt=240:0:0

module load starccm
starccm+ -batchsystem sge -mpidriver intel -batch SIM-FILE
