Treatment of material discontinuities in natural element method for electromagnetic problems

Abstract

International audienceIn this paper the treatment of material discontinuities in the Natural Element Method (NEM) are discussed. A visibility criterion and constrained Voronoi diagram are introduced in order to take account this difficult. The extension of NEM, the so-called C-NEM, is applied to solve electromagnetic problems. An electromagnetic problem is proposed and the approach is evaluated and compared with the traditional Finite Element Method (FEM)
