摘要
讨论了各向异性网格下用一个二次三角形元逼近二阶椭圆问题,利用积分恒等式等一些技巧导出了其超逼近性质,数值算例验证了理论分析的正确性。
A quadratic triangular element is discussed to solve the second order elliptic problem on anisotropic meshes. The superclose property is obtained by the use of the integral identity and some other techniques. The numerical results were given to verify the theoretical analysis.
