Eddy Current Analysis for 3-d Problems Using the Boundary Element Method

A modified boundary integral equation/boundary element method (BIE/BEM) is being developed for eddy current problems in three dimensions. Maxwell’s equations governing the eddy current problems are formulated in two sets of BIE’s, one for the electric field and the other for the magnetic field. These BIE’s involve both the field and the normal derivative of the field, for both exterior (air) an...

Mechanical Stress Analysis by Eddy Current Method

Abstract: A lot of progress is made in the last decade concerning the theoretical and practical aspects of eddy current testing. In addition to the defect characterization, actual studies deal with the metallurgical evaluation of materials. Surface examination allows the prediction of the material strength and consequently its life time. In order to obtain various microstructures and to modify ...

An Adaptive Finite Element Method for the H-ψ Formulation of Time-dependent Eddy Current Problems

Abstract. In this paper, we develop an adaptive finite element method based on reliable and efficient a posteriori error estimates for the H − ψ formulation of eddy current problems with multiply connected conductors. Multiply connected domains are considered by making “cuts”. The competitive performance of the method is demonstrated by an engineering benchmark problem, Team Workshop Problem 7,...

A Computer Program for 2d/rs Eddy Current Problem Based on Boundary Element Method

A computer program, OERSTED, for simulating and analyzing two-dimensional or rotational symmetric eddy current problem with the steady-state sinusoidal time-varying source excitation has been developed at the Integrated Engineering Software (IES). Like other widely used CAE tools developed at IES, OERSTED is a software package based on the most advanced Boundary Element Method (BEM) technique. ...
