Large-scale and Fast Nonlinear Magnetostatic Field Analysis by the Magnetic Moment Method with the Adaptive Cross Approximation

摘要

This paper describes large-scale and fast nonlinear magnetostatic field analyses by the magnetic moment method with the adaptive cross approximation (ACA). To stabilize the convergence characteristic of the Newton-Raphson method, a line search technique is also applied. Some numerical results that demonstrate the validity of the developed method are presented.
