Applied classical electromagnetism, meshers, Method-of-Moments, Radar Cross SectionAbstract
This work presents a multilevel technique developed for speeding-up efficiently the mesh generation process of large and complex bodies for electromagnetic analysis. The targets are meshed by generating intermediate meshes with elements of decreasing size edge until the desired size is reached. The technique minimizes the time of meshing any given geometry and ensures a high quality mesh, as the input geometry at any level is composed of simple surfaces that can be meshed easily. The times of meshing on several geometries with and without the proposed method are compared as well as the quality statistics of the meshes obtained. The Method-of-Moments is used to evaluate the accuracy of the resulting meshes.
