Abstract

In this paper, a new hybrid computational procedure utilizing the element free Galerkin method (EFGM) and the finite element method (FEM) for electromagnetic field analysis is proposed. It is well known that for problems which include moving objects or objects which change their shape, such as in shape optimi-zation, the FEM is not the best solution. For such problem the FEM always requires re-meshing of a part of the entire analysis domain which is computationally very expensive. We have recently proposed a new computational approach based on the EFGM which requires only nodal and boundary condition data to solve for the unknown field. Although free of mesh generation problems, this EFGM exhibits low accuracy if the nodal disposition is not uniform, and longer computation time than the ordinary FEM. To use the advantageous of both EFG-FE method, we developed a new hybrid method. In this paper, the proposed hybrid method is verified using several examples.
