7 Source-Field Method for 3D Magnetostatic Fields

7.1 INTRODUCTION

There are many formulations to solve magnetostatic cases and we have already implemented some [1, 2]. In this chapter we will present the “Source-Field” method, which is a very effective way to solve 3D magnetostatic and magnetodynamic problems. It has been successfully used by several research groups and more recently by our team, the GRUCAD/UFSC [3, 4]. From our collaboration with the L2EP Lille, we started working on this topic and a great deal of their experience was quite useful to implement the method and also to describe it in this chapter. An interesting point related to the following presentation is the use of the tree and co‐tree technique, which is an appropriate ...
