Parallel Electromagnetic Simulations based on Novel Refinement Templates of AMR

A new adaptive refinement method and its parallel implementation of adaptive mesh refinement is developed by regrouping the tetrahedra into 7 refinement templates. In the parallel refinement process, our method only transfers nonconformity messages and refining requirements between corresponding submeshes. The communication algorithm is utilized to update shared information, eliminating the need for a global index in the refinement process. Numerical experiments of a printed dipole antenna, patch antenna, and printed circuit board are presented to validate the accuracy of our new parallel refinement method.
