| Abstract: | A 3-D finite elemnet analysis of the boundary value potential field problem withanisotropic and nonlinear media for multi-medium elements is performed with the variationalmethod. Both the scalar and vector potential models are described. In particular,all dis-cretized results derived from two typical multi-medium eight-node brick-like elements arepresented. These results have been successfully applied to the finitc. element analysis andcomputation of a magnetic field in power transformer cores. |
