Abstract :
Two formulations of the BEM-FEM coupling method for 3D nonlinear magnetostatic problems are developed. Different ways of introducing the Coulomb gauge and handling of the respective boundary terms are discussed. Several iterative methods for the solution of the discretized equations are presented. An example of the TEAM workshop (Testing Electromagnetic Analysis Methods) has been used to examine the numerical behaviour
