Abstract

The potential benefits of employing optimal discretization-based refinement criteria to achieve load balancing in parallel adaptive finite-element electromagnetic analysis are considered. Specifically, the ability of this class of adaption refinement criteria to resolve an effective domain decomposition based on initial discretizations with only relatively few degrees of freedom are examined. The new load-balancing method is evaluated with adaptively refined finite-element solutions for benchmark systems using practical adaption models.
