What Is Multiphysics?
Multiphysics mul·ti·phys·ics [mul-ti-fiz-iks] noun
- Coupled physical phenomena in computer simulation.
- The study of multiple interacting physical properties.
We can describe what happens in the world using sets of physical laws. Since the 1940s, we have been using computers to understand physical phenomena. Originally, computing resources were scarce, so physical effects were observed in isolation. But, as we know, physics do not occur in isolation in the real world.
It's a Multiphysics World
The real world is multiphysics in nature.
Consider your cell phone. The antenna receives electromagnetic waves, the touch screen or buttons are mechanical and electrical components that interact with each other, the battery involves chemical reactions and the movement of ions and electrical current, and so on. A single device, but multiphysics.
With a multiphysics capable simulation tool, you can correctly capture the important aspects of your design.

The COMSOL Multiphysics approach starts with first principles like transport phenomena, electromagnetic field theory, and solid mechanics as the basic fibers of the software. Then, you can weave these fibers together in a self-consistent way to solve your particular simulation needs.
The Multiphysics Cyclopedia is your guide to the underlying concepts and theory behind various interacting physics, and an introduction to coupled simulations.
