迦辽金有限元法结合多边形渐近边界条件技术求解无界平面静电问题
摘要
在文献[1]的基础上
推导出了多边形人工截断边界上的一阶渐近边界条件
使渐近边界条件的应用更加灵活
并采用迦辽金有限元法计算这种类型的边值问题
数值计算表明了该方法的正确性和有效性。
Abstract
On the basis of referance[1]
the first order asymptotic boundary condition on polygonal boundary is derived
which has much wider range of application. And the Galerkin FEM is adopted to solve this kind boundary value problem. The results show the correctness and effectiveness of the proposed method.
