Software Description

Comsol Multiphysics (formerly known as FEMLAB) is a Multiphysics modeling tool that solves all types of problems based on Finite Element Analysis and Partial Differential Equations (PDEs). Predefined applications modes include stress/strain, heat transfer, CFD, and electromagnetics. Additonal features of Comsol Multiphysics include specialized add-on modules for chemical Engineering, Structural Mechanics and Electromagnetics. MSI currently has both education and research licenses. The educational license is COMSOL version 4.1. Contact MSI Help to be added to the COMSOL user list.

MSI has four COMSOL licenses. We ask all users to use the calendar to sign up for time on COMSOL using these instructions. Although MSI does not have any rigid policy regarding signing up in advance, you cannot monopolize a license.

The COMSOL/Research license is the default. The COMSOL/Class license is available to instructors using COMSOL in their curriculum.

Available Modules

The following additional modules are available. If you need to use any of these modules, PLEASE SPECIFY THE MODULE(S) on the calendar when you make your reservation. Verify that all the licenses have not been reserved by others for the same time period. Users found using modules without prior reservations are subject to having their job killed if someone else has reserved the module for the same time.

General Linux

When using COMSOL at MSI, please make sure to check that the amount of memory allocated to your job is sufficient. COMSOL recommends at least 4 GB of memory. We have found that sometimes 8 GB is required.

To use the COMSOL research license (default) interactively in a Linux environment use the commands:

module load comsol
comsol

If you are using a remote X or NX session and see GL errors when trying to start Comsol, try this:

module load comsol
comsol -3drend sw

There are known problems using Comsol over NX. We suggest you use the NICE connection.

To use the class license

module load comsol/class
comsol

Check License Usage

You may check the current license usage from the Linux environment with the following command. You may need to scroll up to see "Users of COMSOL" in the output:

lmstat -a -c 1716@lmcomsol.msi.umn.edu

The output will look like this (truncated):

...
