Running using the CC installation
STAR-CCM+ is only available on the CC software stack. On Niagara you must run the following module commands:
module load CCEnv module load StdEnv module load starccm/12.04.011-R8
Setting up your .star-12.04.011 directory
STAR-CCM+ version 12.04.011 will attempt to write to your $HOME/.star-12.04.011 directory. This will work when you are testing your workflow on the login nodes, because they can write to $HOME. However, recall that the compute nodes cannot write to the /home filesystem. If you attempt to run STAR-CCM+ from a compute node using the default configuration, it will fail because STAR-CCM+ cannot write to $HOME/.star-12.04.011.
The solution is to create an alternative directory called $SCRATCH/.star-12.04.011, and create a soft link from $HOME/.star-12.04.011 to $SCRATCH/.star-12.04.011:
mkdir $SCRATCH/.star-12.04.011 ln -s $SCRATCH/.star-12.04.011 $HOME/.star-12.04.011
This will fool Ansys into thinking it is writing to $HOME/.star-12.04.011, when in fact it is writing to $SCRATCH/.star-12.04.011. This command only needs to be run once, though it needs to be run for each version of STAR-CCM+ you run.
