Rectangular finite element method with moving grid for parabolic problem 突聾預(yù)后相關(guān)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(duì)各向異性有限元進(jìn)行了研究,構(gòu)造了一個(gè)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(wú)關(guān)的誤差估計(jì)。
