摘要
本文采用有限元-边界元耦合法解无限区域中的轴对称涡流问题。边界元法中的基本解是经由Green函数的概念导出。文中计算了一个实例,并与解析解作了比较。
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.
