'''Multiphysics''' treats [[simulation]]s that involve multiple physical models. 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.

[[ANSYS Multiphysics]],[[CFD-ACE+]], and[[CFD-FASTRAN]], [[COMSOL Multiphysics]] are twosome examples of commercially available software packages for simulating multiphysics models.

Almost any physical simulation involves coupled systems, like E and B field 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. And [[Maple computer algebra system]] has no problems with coupled equations, only with PDEs. To really appreciate '''multphysics''' one has to consider how previous software packets, especially the educational ones, dumbed down the user.
