“…However, making such a suitable mesh is a bottleneck to the easy and wide use of the FEM, since the mesh-making work is time-consuming. Moreover, the analysis accuracy and the computation time depend on the mesh characteristics, e.g., number of nodes, number of elements, and shape of elements, which require some experience for the user to make a suitable mesh.Therefore,theadaptiveFEM [1]- [4]isoneofthepromising numerical analysis techniques for users without experiment and even with enough experiences.By applying the adaptive FEM, the mesh is automatically and appropriately refined, and produces results whose error is less than the permissible error. The adaptive FEM has three important schemes: true value estimation scheme, error evaluation scheme and mesh control scheme.…”

The finite-element analysis is widely used in design stage of electromagnetic apparatuses. The analysis accuracy depends on the characteristics of the finite-element mesh, e.g., number of nodes, number of elements and shape of elements. Recently, the adaptive finite-element analysis is one of the most promising numerical analysis techniques. In process of the adaptive finite-element method, the error evaluation is one of the important schemes. In this paper, a new error evaluation scheme, which is suitable for electromagnetic problems, is proposed. The proposed error evaluation method is then applied to two-dimensional and three-dimensional magnetostatic field problems for its verification.Index Terms-Adaptive finite-element analysis, adaptive meshing, electromagnetic problem, error evaluation.
