Multiphysics is a very important engineering practice, especially in mechanical engineering. With multiphysics calculations, you can observe and interpret physical conditions where different kinds of engineering practices are on stage. For example, if you want to simulate a car crash accident to see the behavior of your design in an accident, different kinds of practices such as non-linearities, linearities, material behavior, etc. are in stage.
