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.
Specifically, COMSOL Multiphysics is a simulation platform that encompasses all of the steps in the modeling workflow — from defining geometries, material properties, and the physics that describe specific phenomena to solving and postprocessing models for producing accurate and trustworthy results.
The COMSOL Multiphysics is hosted on a secure Azure Cloud and to be used simultaneously by up to 60 users located anywhere in the country. It is intended to offer the cloud-based COMSOL Multiphysics through the I-STEM web portal to researchers around the country, who are registered with the portal. It is expected to be used widely and regularly by many researchers, especially those in the smaller institutions which cannot often afford to license COMSOL.
