Wideband Model Order Reduction for Macromodels in Finite Element Method

Abstract

Abstract: This paper presents a novel algorithm for accelerating 3D Finite Element Method simulations by introducing macromodels created in local model order reduction in the selected subdomains of the computational domain. It generates the projection basis for a compact system of equations associated with a separate subdomain. Due to non-linear frequency dependency in the Right Hand Side (RHS), the standard reduction methods do not perform properly. The proposed algorithm alleviates this problem being easy to implement and accurate in wide frequency band simulations of complex structures.
