What is COMSOL?

This guide summarizes the most important information about COMSOL Multiphysics at RWTH, including licensing, support, and learning resources.
General Information
COMSOL Multiphysics is a program for modeling and calculating multiphysics problems based on partial differential equations.
The software has a modular structure. In addition to the basic COMSOL Multiphysics package, there are numerous modules in the fields of chemistry, electronics, mechanics, fluid dynamics, multipurpose, and interfacing. A list of the modules currently included in the licenses can be found here.
License Information
Currently, two different COMSOL licenses are offered: one for academic research (FNL licenses) and one for teaching (CKL licenses). Please note that the use of teaching licenses is exclusively permitted for courses, as well as for bachelor's and master's theses.
License Usage Restriction
To ensure fairer use, access has been limited to the number of purchased licenses. Access is only possible from the IP address ranges you have provided to us and via the RWTH High-Performance Computing Cluster with the user accounts specified by you. This information must be provided to us when purchasing a new license or extending an existing one.
