"In many non-standard engineering development applications it strongly pays off to invest an effort into understanding the physics of the problem prior to undertaking complex numerical simulations. The better the knowledge of the leading physical effects in a complex system, the simpler and more cost-efficient the analytical model can be. Moreover, the understanding of the most important physical driving effects often enables one to build a simplified, closed-form mathematical effective model. Such models usually give insight into the interplay of various parameters governing the physical behavior of the complex system. In this way, a fast pre-optimization of the desired features is often possible. Subsequently, the rich arsenal of ANSYS multiphysics capabilities can be used to refine the judgements and obtain the desired quantitative solutions."
