Efrom surface equivalence principle to modular domain decomposition

Abstract

For the simulation of complex models and complete systems whose components involve different electromagnetic scales and properties, it is often appropriate to apply domain decomposition methods. Based on the surface equivalence principle, the aim of the presented project is to develop a modular, black box framework for domain decomposition which is capable of assigning any formulation and numerical method to a certain subdomain. In this approach, equivalent surface currents act as interface between the subdomains exchanging boundary data. Here, the focus is on coupling finite element and boundary element frequency domain methods driven by application examples like antenna placement. First results and encountered challenges will be presented.
