摘要
基于曲边有限元(CFEM)的自然边界元理论,设计出带CFEM的D-N交替算法,来解决无穷凹角区域上的各向异性外问题,并给出了近似解与真解之间的误差估计和收敛性.
Based on the natural boundary element theory of curved edge finite element,a D-N alternating method with curved edge finite element is established to solve anisotropic elliptic exterior problem in the infinite domain with a concave angle,and to give the error estimation and convergence of the approximate solution of the D-N alternating method.
