'''Multiphysics''' treats [[simulation]]s that involve multiple physical models or multiple simultanoussimultaneous physical phenomena. For example, combining [[chemical kinetics]] and [[fluid mechanics]] or combining [[finite elements]] with [[molecular dynamics]]. Multiphysics typically involves solving coupled systems of [[partial differential equation]]s.
 
Almost any physical simulation involves coupled systems, like '''E''' and '''B''' (electric and magnetic) fields for electromagnetism or pressure and velocity for sound or the real and the imaginary part of the quantum mechanical wave function. Or consider the mean field approximation for the electronic structure of atoms, where the electric field and the electron wave functions are coupled.
