Design case 2: Reduced Order Modeling of Coupled Systems Finite Element Model: Design case 1 has demonstrated the common approach of using analytical models for the early phases of design and finite element simulations for a comprehensive study of the component behaviour. This procedure is very accurate but requires un- reasonable large computing time, especially for harmonic and transient analyses. Design case 2 shall illustrate the enormous speed up of coupled domain simulations which becomes possible after the finite elements models are reduced to low order black- box models with a few input and output terminals. Remarkable is that the Reduced Order Models achieve almost the same accuracy as that of full finite element runs but can be processed with speed known from circuit and system simulators.
