Coupling of model order reduction and multirate techniques for coupled dynamical systems

In refined network simulation one is faced with simulating coupled dynamical systems, as for instance circuits are to heat or electromagnetics. Simulation costs of such systems can be reduced by both model order reduction and multirate techniques. this paper we discuss the coupling approaches linking slowest-first technique nonlinear proper orthogonal decomposition reduction. For a thermal–electrical test example numerical results show proven convergence combined scheme.
