Abstract

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.

Abstract

Since a magnetic field is inherently invisible, it is useful to develop effective-teaching materials which can make beginning electromagnetics-learners imagine a magnetic field. We have previously developed a method to combine Augmented Reality (AR) technology and real-time simulation to visualize an electromagnetic field, however, this visualization system cannot depict an actual magnetic field. Therefore, we have newly developed a teaching material to measure an actual magnetic field distribution by using many 3-axis magnetic field sensors and we have studied a method to effectively visualize a magnetic field. In this paper, we report a developed hardware configuration and software functions. This developed visualization system utilizes AR technology, and it is possible to observe a measured magnetic field in 3D space.
