Anisotropic Biquadratic Finite Element with Some Natural Superconvergence Results
摘要
纸在各向异性的网孔上为 Poisson' 问题学习集中和四乘幂的有限元素的 superconvergence。由详细分析，它证明四乘幂的有限元素是各向异性地，在四高斯的 superconvergent 指在元素。
The paper studies the convergence and the superconvergence of the biquadratic finite element for Poisson＇ problem on anisotropic meshes. By detailed analysis, it shows that the biquadratic finite element is anisotropically superconvergent at four Gauss points in the element. Key words：
