A Multiresolution Domain Decomposition Preconditioner for the MoM Solution of Multiscale Complex Structures

In this communication, we present the combination of a high scalability implementation of the multibranch–multiresolution preconditioner with the domain decomposition method for the electromagnetic analysis of geometrically complex structures with different levels of multiscale features and discretized with a possible nonconformal mesh. Finally, a numerical experiment is shown to illustrate the great efficiency of the proposed approach for the solution of large multiscale objects.
