Three-Dimensional Element Free Galerkin Method and Its Applications in Electromagnetic Field Numerical Analysis
摘要
Abstract
The element free Galerkin method (EFGM) for problems in three-dimensional (3D) electromagnetic computations was proposed in this paper. The EFGM is based on moving least square (MLS) approximations and uses only a set of nodes to formulate the discrete model. Therefore, it can solve some problems that the finite element method (FEM) can not solve effectively in electromagnetic field, such as thin plate, narrow gap, moving conductor problems, etc. In this paper, the influence of weight functions to the EFGM was studied thoroughly, the regularity of the influence domain width and the formula of the influence radius of nodes in three dimensional computations were given.关键词
