Adaptive mesh refinement for time-domain electromagnetics using vector finite elements :a feasibility study

Pasik, Michael F.; Kotulski, J.D.; Turner, C.D.

This report investigates the feasibility of applying Adaptive Mesh Refinement (AMR) techniques to a vector finite element formulation for the wave equation in three dimensions. Possible error estimators are considered first. Next, approaches for refining tetrahedral elements are reviewed. AMR capabilities within the Nevada framework are then evaluated. We summarize our conclusions on the feasibility of AMR for time-domain vector finite elements and identify a path forward.
