Voxel Based Finite Element Method Using Homogenization

摘要

The voxel mesh is one of the effective technique for reducing the cost of mesh generation. However poor ability of expression for curved surfaces is a drawback to be solved and decreases the accuracy of finite element analyses. In this paper, we introduce a homogenization method for the voxel elements on the surfaces of magnetic objects. The anisotropic permeability determined by the present method improves the accuracy of analyses. The numerical results show that the proposed method has smaller errors of inductance in a three dimensional magnetostatic analysis in comparison with the conventional method.
