【Abstract】 A new method for calculating the longterm transient process of linear magnetic field has been developed. In such method, Fast Fourier Transformation algorithm is introduced to the finite element analysis, by which good results are obtained with the help of transformation error reduction technics, as the calculated examples shown. Moreover, the time-interval results are interpolated.更多还原
