Abstract

This paper presents a procedure for using integrals to solve nonlinear magnetostatic field problems. An integral equation on magnetized volume, expressed in terms of magnetic field H or magnetization M, is discretized by means of edge elements on a tetrahedral mesh and solved numerically by means of a collocation method. The procedure approaches nonlinear by means of the fixed-point iterative technique. It sets up two different iterative schemes with complementary features. This paper gives details about implementation and presents and discusses results on some test cases
