You can model and simulate any physics-based system using software from COMSOL®. COMSOL Multiphysics® includes the COMSOL Desktop®graphical user interface (GUI) and a set of predefined user interfaces with associated modeling tools, referred to as physics interfaces, for modeling common applications. A suite of add-on products expands this multiphysics simulation platform for modeling specific application areas as well as interfacing with third-party software and their capabilities (from: https://www.comsol.com/products).

Currently availabe are concurrent licenses for the following products:

  • COMSOL Multiphysics
  • AC/DC module
  • CAD import module
  • CADREADER
  • CFD module
  • DESIGN module
  • ELECTROCHEMISTRY module
  • HEATTRANSFER module
  • Matlab Link module
  • MICROFLUIDICS module
  • Particle Tracing module
  • RAYOPTICS module
  • Structural Mechanics module 
  • WAVEOPTICS optics module

You can get an up-to-date list of module and current usage on PAL or Maxwell with the command 'my-licenses -p comsol'

Getting access to COMSOL Multiphysics

Using COMSOL Multiphysics is subject to academic license conditions requiring your explicit consent. If you would like to use COMSOL Multiphysics send an email to uco@desy.de stating that you have read and acknowledge the following license conditions:

  1. Installation: COMSOL licenses can only be installed on computers on the Campus of DESY (Hamburg and Zeuthen). Any other installation, in particular on private computers is not allowed. 
  2. Usage: COMSOL licenses can only be used for academic research and education. Any other usage, in particular for industrial application, services for industrial partners or in co-operation with industrial partners is prohibited. 

Once you have contacted UCO we will grant your DESY-account access to the COMSOL licenses.

Please note that access to the license server is not possible from outside DESY. Likewise access to installation media is only possible with a DESY-account (web) or from within the DESY-intranet (afs).

Using COMSOL Multiphysics (MAXWELL only!)

Usually Comsol Multiphysics can be invoked directly as a (versioned) command

[me@maxwell ~]$ /software/comsol/5.2/multiphysics/bin/comsol              # or if using remotely, you might need to specify the renderer 
[me@maxwell ~]$ /software/comsol/5.2/multiphysics/bin/comsol -3drend sw
# Alternatively the setup can be initialized via modules:
[me@maxwell ~]$ module load maxwell
[me@maxwell ~]$ module load comsol
[me@maxwell ~]$ comsol

Check https://www.comsol.de/support/knowledgebase/933/ for information about rendering. In general, accessing maxwell via FastX2 will be give a considerably better experience than using ssh for remote access.

Getting support

For basic support contact uco@desy.de. For in-depth technical questions the COMSOL technical support is available. Asking for support at COMSOL you will need the license number (check "Licensed products" under "Options").  COMSOL comes with an extensive Help-System. Some of the manuals can also be found in the COMSOL installation folder, on maxwell have a look at /software/comsol/5.2/multiphysics/doc/pdf/.

Installing COMSOL Multiphysics manually

The installation procedure is very similar for Linux, Mac OSX and Windows. All information needed can be found under COMSOL Downloads & Licenses (or in /afs/desy.desy/products/source/comsol/). The folder is only accessible with a DESY username and password. Available installer:

COMSOL(version)_dvd.isoanyISO ImageMount the iso image with the OS specific tool. For Windows execute the setup.exe, for Mac OSX or Linux the ./setup file.

COMSOL(version)_lnx.tar.gz

COMSOL(version)_mac.dmgOSXMac online installerInstaller pulls the installation files from remote server.
COMSOL(version)_win.exeWinWindows online installerInstaller pulls the installation files from remote server.


Installing COMSOL Multiphysics on Linux

By far the simplest is to use the online installer. Fetch the tarball from https://linux.desy.de/distributions/redhat_derivatives_at_desy/software/downloads/comsol/ or directly from  comsol or directly from AFS (if you have an AFS client installed):

[me@rhel ~]$ mkdir COMSOL
[me@rhel ~]$ tar xf /afs/desy.de/products/source/comsol/5.3/COMSOL53_lnx.tar.gz -C COMSOL  # example for v5.3. There might be newer releases!
[me@rhel ~]$ cd COMSOL
[me@ubun ~]$ ./setup  # See snapshots below
