Multiphysics plays an equally strong role is in the design of subsystems and how they interact with other subsystems and systems. One example is MEMS (microelectromechanical systems) which typically include small moving parts such as wheels, rotors,levers, and linkages, and how they operate within larger systems. Other examples include the creation of"designer materials" tailored for specific environments,as well as the simulation of nanoscale mechanics of cancer cells and how that is being extended to medical treatment devices and methods.
