An Efficient Strategy for Distributing the Mesh of Parallel Electromagnetic Solvers Based on the AIM

Abstract

Parallel electromagnetic solvers require efficient strategies to distribute the mesh of large structures encountered in advanced antenna designs. In addition, parallel solvers based on the adaptive integral method (AIM) require processes to access additional mesh entities that lie within the near region of their mesh partition. In this paper, we propose a parallel solution for loading, processing, partitioning, and redistributing the mesh of AIM-based solvers. The proposed method is demonstrated on problems as large as 200 wavelengths, with up to 200 million unknowns, and up to 8000 cores involved.
