A Priori Error-Controlled Simulation of Electromagnetic Phenomena for HPC

Abstract

In this project we aim to construct a high fidelity boundary condition module for Maxwell's equations that can be interfaced with major time-domain electromagnetics solver systems. There is ample need in the EM modeling community for reliable and stable far field boundary conditions of high accuracy. Most existing methods are limited in one or more of these requirements, and recent developments in the CRBC procedure (as originally presented by Hagstrom and Warburton in 2009), have made the technique an attractive candidate for implementation in multi-purpose solvers. In phase-I of this project we implemented and improved upon many aspects of this method, particularly in light of the needs of high order accurate Maxwell equations solvers (based on the discontinuous Galerkin method). Error bounds were computed and demonstrated for a number of cases. We continue in the second phase of this project to improve upon the robustness of this method, as we develop a software platform which shall be its flagship (and open source) implementation. In this first quarterly report we present initial progress to this end, showing recent mathematical developments, project coordination plans and some results from our initial experience with MEEP.
