3D Magnetic Field Computation of TEAM Problem 13

摘要

A method to deal with periodic boundary condition in 3D magnetic field computation has been presented in this paper. The vector potentials on the periodic boundary are served as non-independent variables and the FEM formulations of magnetic vector potential have been developed as well. By means of this analysis, the unknown boundary integrals on the periodic boundary condition are not only removed from the traditional FEM equations, but also the storage of computer is greatly reduce.d Finally, the TEAM problem 13 been calculated and the results has proved the presented method is correct.
