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
