Abstract：In order to resolve the problem of low computational efficiency of element-free Galerkin method, the paper introduces the accelerated iterative multigrid method to the element-free Galerkin discrete field, and proposes a multigrid method of element-free Galerkin (EFG-MG). The node group is used to construct coarse nodes and the restriction operator is disposed in terms of the relation of coarse nodes and fine nodes. It is used to numerical computation of electromagnetic field problems, and the high efficiency of element-free Galerkin method is proved by examples.
