Description

From the COMSOL Website: COMSOL Multiphysics® is a general-purpose software platform, based on advanced numerical methods, for modeling and simulating physics-based problems. With COMSOL Multiphysics, you will be able to account for coupled or multiphysics phenomena. With more than 30 add-on products to choose from, you can further expand the simulation platform with dedicated physics interfaces and tools for electrical, mechanical, fluid flow, and chemical applications. Additional interfacing products connect your COMSOL Multiphysics simulations with technical computing, CAD, and ECAD software.

Running Jobs via Web Apps

The COMSOL user guide is essential to understanding the application and making the most of it. The guide and this page should help you to get started with your simulations. Please refer to the Documentation section for a link to the guide.

  • Note on CIRCE: Make sure to run your jobs from your $WORK directory!
  • Note: Scripts are provided as examples only. Your SLURM executables, tools, and options may vary from the example below. For help on submitting jobs to the queue, see our SLURM User’s Guide.

Running COMSOL on CIRCE

The COMSOL user guide is essential to understanding the application and making the most of it. The guide and this page should help you to get started with your simulations. Please refer to the Documentation section for a link to the guide.

  • Note on CIRCE: Make sure to run your jobs from your $WORK directory!
  • Note: Scripts are provided as examples only. Your SLURM executables, tools, and options may vary from the example below. For help on submitting jobs to the queue, see our SLURM User’s Guide.

Running Comsol on CIRCE is quite trivial. When you are ready to run the solver against your model, save the model and copy the ‘.mph’ file to CIRCE via which ever method you prefer and run: 

sbatch --job-name=mymodel.mph runcomsol.sh

You will need to add the following information in a script file and reference it in the sbatch command argument: 

#!/bin/bash
#
#SBATCH --time=04:00:00
#SBATCH --mem-per-cpu=2048
#SBATCH --ntasks=8

#### SLURM 8 processor COMSOL test to run for 4 hours.

module purge
module add apps/comsol/5.2a

export TMPDIR="/path/to/temp/dir"

comsol -clustersimple batch -inputfile ${SLURM_JOB_NAME} \
       -outputfile ${SLURM_JOB_NAME//\.mph/}.out.mph \
       -batchlog ${SLURM_JOB_NAME}.${SLURM_JOB_ID}.comsol_log \
       -tmpdir $TMPDIR


For non-distributed, SMP jobs, the following script will work: 

#!/bin/bash
#
#SBATCH --time=24:00:00
#SBATCH --mem=16384
#SBATCH --nodes=1
#SBATCH --ntasks-per-node=12

#### SLURM 12 processor COMSOL test to run for 24 hours.

module purge
module add apps/comsol/5.2a

export TMPDIR="/path/to/temp/dir"

comsol batch -np ${SLURM_NTASKS} -inputfile ${SLURM_JOB_NAME} \
        -outputfile ${SLURM_JOB_NAME}.${SLURM_JOB_ID} \
        -batchlog ${SLURM_JOB_NAME}.${SLURM_JOB_ID}.comsol_log \
        -tmpdir $TMPDIR


Solution data will be stored within the ‘.mph’ file and can be viewed on your local machine simply by copying the file back once you are done. A preferred way to deal with this is to use your home directory share to map your CIRCE home directory as a network drive. Then, you can simply save the file to the network drive, move it to your /work directory, and run the simulation on CIRCE. When the simulation is complete, copy the file back to your home on CIRCE, and re-open the file to review the results on your desktop.
