The capability to model large-scale problems in electromagnetics (problem sizes extending to thousands of wavelengths) using physics-based full wave solvers that employ high-fidelity geometric models and high- order accurate numerical algorithms is a critical technology for several aspects of the DoD warfighter mission.  In particular, a robust and computationally efficient computational electromagnetics (CEM) environment is desired by NAVAIR to accurately predict the EM fields and radiation characteristics of installed antenna arrays coupled with radomes present in many Navy platforms. To meet these goals, HyPerComp has been developing and bringing together various advanced computational technologies in both time-domain (HDphysics-RFT) and frequency-domain (HDphysics-RFF).  Some of them are, 1) high-order, discontinuous Galerkin (DG)-based framework for Maxwell’s equations, 2) high-order curved geometry representation, 3) automatic CAD repair tools and hybrid structured/unstructured gridding, and 4) high-order absorbing outer boundary conditions.  The goal of Phase II is to fully mature the capabilities developed in Phase I and deliver a GUI-driven software package that ensures geometric fidelity is not compromised for the generation of a computational electromagnetics (CEM) mesh formed by high-order curved elements. We will continue developing the master GUI, CEMax that integrates all the advances in preprocessing (CAD import/repair and gridding), processing (CEMprep, HDphysics-RFT and HDphysics-RFF), optimization algorithms, and postprocessing tools (CEM-post), deliver the capabilities to the RACEMM group at NAVIAR, and support their program needs.
