COMSOL

COMSOL is a multiphysics solver that provides a unified workflow for electrical, mechanical, fluid, and chemical applications.

COMSOL is available on Mahuika.

Run;

module load COMSOL

to load the COMSOL module.

comsol --help

Will display a lift of COMSOL batch commands.

Licencing

Currently we only have access UoA physics faculty's licence server. If you are eligible to use this licence contact NeSI support so you may be added to the user group.

If you would like to use another licence please contact NeSI support.

 

Example Script


#!/bin/bash -e
#==========================================#
#SBATCH --job-name          COMSOL_run1
#SBATCH --time              05:00:00
#SBATCH --cpus-per-task     8       #Remember to halve with #nomultithread
#SBATCH --mem               10G
#SBATCH --output            COMSOL-%j.out
#SBATCH --hint nomultithread #SBATCH --licenses comsol@uoa_physics #==========================================# INPUT_FILE="/nesi/project/nesi99999/input.mph" OUTPUT_FILE="/nesi/nobackup/nesi99999/output.mph" #==========================================# cat ${0} module load COMSOL/5.3 comsol batch -inputfile $INPUT_FILE -outputfile "output${SLURM_JOBID}.mph"

 

Resource requirements


COMSOL does not support MPI therefore #SBATCH --ntasks should never be greater than 1.

Memory requirements depend on job type, but will scale up with number of CPUs ≈ linearly.

Hyper-threading can benefit jobs using less than 8 CPUs, but is not recommended on larger jobs.

Performance is highly depended on the model used. The above should only be used as a very rough guide.
