Abstract

A general framework for the analysis of perfect electric conductor structures is presented; the proposed strategy is based in the decomposition of single structure into non-connected domains, whose individual analysis are used as preconditioner, obtaining good convergence properties for the iterative solution of the entire structure. Transmission conditions between the sub-domains are imposed using discontinuous Galerkin, and then are enhanced by enlarging the sub-domains information.
