Abstract :
A novel iterative algorithm for the application of BEM-FEM coupling to nonlinear magnetic problems is presented. It combines an algorithm for nonlinear solution with an algorithm for memory saving. The resulting iterative method contains a relaxation parameter which is determined adaptively. The proposed algorithm exhibits superior numerical performance compared,to earlier ones
