Element-Free Galerkin Method for Electromagnetic Field Computations

Although numerically very ecient the nite element method exhibits diculties whenever the remeshing of the analysis domain must be performed. For such problems utilizing meshless computation methods is very promising. In this paper, a kind of meshless method called the element-free Galerkin method is introduced for electromagnetic eld computation. The mathematical background for the moving least square approximation employed in the method is given, and the numerical implementation is briey discussed. Application of the proposed method for electromagnetic eld computation and veri cation of the obtained results using theoretically known solution is also presented
