An Accurate Edge-based FEM for Electromagnetic Analysis with Its Applications to Multiscale Structures

29 Oct 2019 Zhang Yangfan Wang Pengfei Li Wenping Yang Shunchuan

This paper introduces an accurate edge-based smoothed finite element method (ES-FEM) for electromagnetic analysis for both two dimensional cylindrical and three dimensional cartesian systems, which shows much better performance in terms of accuracy and numerical stability for mesh distortion compared with the traditional FEM. Unlike the traditional FEM, the computational domain in ES-FEM is divided into nonoverlapping smoothing domains associated with each edge of elements, triangles in two dimensional domain and tetrahedrons in three dimensional domain...
