====== COMSOL 5.2a ======

==== Module ====

<code> module load COMSOL/5.2a
</code>

----


==== Job script threaded version (no MPI) ====

You can use only one node in this case. Create a job file called ''%%job_smp.sh%%'':

''%%/opt/ohpc/pub/examples/slurm/mul/comsol%%''

<code>
#!/bin/bash
#
#SBATCH -J comsol
#SBATCH -N 1
#SBATCH -o job.%j.out
#SBATCH -p E5-2690v4
#SBATCH -q E5-2690v4-batch
#SBATCH --ntasks-per-node=28
#SBATCH --threads-per-core=1
#SBATCH --time=04:00:00
#SBATCH --mem=16G

# Details of your input and output files
INPUTFILE=micromixer_cluster.mph
OUTPUTFILE=micromixer.out

# Load our comsol module
module purge
module load COMSOL/5.2a

# create tmpdir 
TMPDIR="/tmp1/comsol"
mkdir -p $TMPDIR

## Now, run COMSOL in batch mode with the input and output detailed above.
comsol batch -np $SLURM_NTASKS -inputfile $INPUTFILE -outputfile $OUTPUTFILE -tmpdir $TMPDIR
