A Computationally Efficient Finite Element Analysis Algorithm Considering Two-Dimensional Magnetic Properties

Abstract

For taking account of the two-dimensional magnetic properties of grain-oriented electrical steel, the effective anisotropic tensor reluctivity is examined, and a computationally efficient algorithm is suggested by using response surface method (RSM) to smooth the two-dimensional magnetic properties. It is shown that the reconstructed two-dimensional magnetic properties are fairly effective to stabilize the convergence of the Newton-Raphson iteration in the nonlinear magnetic field analysis
