Rectangular finite element method with moving grid for parabolic problem 突聾預后相關因素的分析
In this paper , we first focus on the anisotropic finite elements and construct a hermite rectangular finite element which can be applied in 2nd order elliptic problem . lt is proved that this finite element has anisotropic property and its error estimate is obtained without the limitation of regularity conditions 本文首先對各向異性有限元進行了研究,構造了一個用于二階問題的hermite型矩形元,證明了該單元具有各向異性特征,并且給出了與剖分的正則性無關的誤差估計。
