The COMSOL Multiphysics software suite is used worldwide as an indispensable tool for a variety of computer simulations for R&D as well as for learning. It is a general-purpose simulation software package for modeling designs, devices, and processes in all fields of engineering, manufacturing, and scientific research. In addition to using multiphysics modeling for one’s own projects, one can also turn the resulting models into simulation applications for use by other design teams, for manufacturing, and for testing.
