摘要：

In order to solve the nonlinear equation system arising when solving magnetic fields with the finite element method, very often the Newton-Raphson method is applied. Sometimes it is advantageous or necessary to apply relaxation factors in order to improve the convergence. In this paper reasons and workarounds for the convergence problem are discussed.
