| Abstract: | This paper deals with the hybrid FE-BE formulation and the solution for axi-symmetric eddy current problems with an open region. In the conductor region, a conventional FEM is formulated. In the open region, the BEM formulation is proposed, in which the fundamental solution of the governing equation is derived through the potential concept of Green's function. The two formulations are matched on the conductor contour.An example is given for illustration and the numerical results are compared with those obtained by analytical solution. |
