#SBATCH --time=11:00:00
#SBATCH --job-name test

module use /scinet/niagara/software/commercial/modules
module load comsol/5.3.1.275

# DIRECTORY TO RUN - $SLURM_SUBMIT_DIR is directory job was submitted from
cd $SLURM_SUBMIT_DIR

NCORE=$((SLURM_NTASKS * SLURM_CPUS_PER_TASK))
comsol batch -np $NCORE -inputfile micromixer_batch.mph -outputfile output.mph
