You can start the graphical user interface (GUI) of COMSOL on one of the login nodes of Euler. This can be useful to change your COMSOL preferences or to prepare a model or check the result of a COMSOL job.

Starting the GUI

In order to start the GUI of COMSOL on a login node, you first need to establish an SSH connection with X11 forwarding enabled.

ssh -Y username@hostname

With username being your NETHZ username. Afterwards, you can load one of the COMSOL modules

module load comsol/5.1

and finally start the GUI with the comsol command.

comsol

Problems with the COMSOL 5.2 GUI

We noticed, that in some cases, the COMSOL 5.2 GUI updates very slowly when staring it on Euler or sometimes it even crashes. If you experience this kind of problem, then you can try to start the COMSOL GUI with the following option:

comsol -3drend sw

If the problem still persists, the reason could be that you are on a login node, which is overloaded. We recommend in this case to log out and log in to the cluster again.
