讨论了各向异性非协调矩形元对二阶抛物方程的逼近,利用该单元的特殊性质及新的技巧,在各向异性网格下得到了与传统有限元方法完全相同的最优的误差估计。
In this paper, anisotropic nonconforming rectangular finite element approximation to the second order parabolic equations is studied. The optimal error estimate same as the traditional finite elemetnt methods is obtained by use of the special properties of the element and some novel techniques.
