A new adaptive mesh refinement method in FEA based on conservation of magnetic field at interface between two elements

Mesh quality strongly affects the solution accuracy in electromagnetic finite element analysis (FEA). Hence, the realization of adequate mesh generation becomes a very important task. Although highly experienced users with sufficient knowledge of the electromagnetic phenomenon could easily resolve this problem, to aid in these matters especially for beginners in the field computation, several adaptive meshing methods have been proposed for automatic adjustment of the mesh density in accordance with the shape and difficulty of the analyzed problem. In this paper, a new type of adaptive meshing method based on the conservation of the magnetic field is proposed.
