Comsol Multiphysics (previously named Femlab) is a modeling package for the simulation of any physical process you can describe with partial differential equations (PDEs). It features state-of-the-art solvers that address complex problems quickly and accurately, while its intuitive structure is designed to provide ease of use and flexibility.

• Comsol: Support

• Module Name: Comsol (see the modules page for more information)
• Interactive Only

An X-Windows connection is required.

Allocate an interactive session and run the program.
Sample session (user input in bold):

[user@biowulf]$ sinteractive --cpus-per-task=14 --mem=20g --gres=lscratch:100
salloc.exe: Pending job allocation 46116226
salloc.exe: job 46116226 queued and waiting for resources
salloc.exe: job 46116226 has been allocated resources
salloc.exe: Granted job allocation 46116226
salloc.exe: Waiting for resource configuration
salloc.exe: Nodes cn3920 are ready for job

[user@cn3920 ~]$ module load Comsol
[user@cn3920 ~]$ comsol -tmpdir /lscratch/$SLURM_JOB_ID

[user@cn3920 ~]$ exit
salloc.exe: Relinquishing job allocation 46116226
[user@biowulf ~]$

You should see the Comsol Desktop image as below:

After the first time running, the default location of Comsol output is generated in your home directory:

[user@biowulf]$ ls ~/.comsol
v61

Because your /home directory is limited in space, it is a good idea to move and symlink the ~/.comsol directory to your /data directory, where there is a much larger amount of disk space available. This can be done like this:

[user@biowulf]$ mv ~/.comsol /data/$USER/comsol ; ln -s /data/$USER/comsol ~/.comsol
