摘要：

A modified fixed-point iteration algorithm is proposed for electromagnetic finite element analysis with a hysteretic material model. In this method, the convergence factor is dynamically adjusted at each time step based on the specific situation. It has been verified that this approach improves computational speed and stability in solving nonlinear hysteresis electromagnetic simulation problems.
