Abstract

In this paper a simple mesh refinement technique for finite element method is proposed using error estimation only on the material boundaries. The boundary errors are estimated by the continuity conditions of normal B field and tangential B field. From the error estimation fine meshes are accomplished on the boundary and propagate to the near region by Delanunay mesh tessellation. This adaptive mesh refinement technique is applied to the force calculation of magnetic clutch composed by several material regions and makes good convergence.
