Novel parallel meshing technique implemented into parallel FDTD simulation using function language for solving electrically large and complex EMC problems

It is well known that in all FDTD simulations for predicting electromagnetic responses of various two- and three-dimensional structures, we always need to generate their appropriate meshes. In particular, for conformal and other enhanced FDTD algorithms, appropriate meshing is very important and it is directly related to the simulation accuracy. The real-world model, such as aircraft and ship platform etc., often contains millions of surface patches, thus parallelization for meshing is an effective way for improving the FDTD simulation efficiency. In this paper, one complete parallelized meshing technique combined with fast parallel FDTD computation workflow is developed and several testing examples are presented for validating our algorithm. With its successful implementation, surface current distributions overall an aircraft and a warship platform with aircrafts in the presence of an electromagnetic pulse are captured and examined, respectively. We would like to emphasize that high parallel efficiency is achieved during our simulations for solving a lot of EMC problems.
