求翻譯:本文主要研究二階橢圓問題的混合有限元方法。首先,我們基于余能原理的變分形式,設(shè)中間變量,并引入空間及其范數(shù),導(dǎo)出此二階橢圓問題的混合模型。然后,應(yīng)用最低階的混合元,我們構(gòu)造網(wǎng)格上單元和邊的基函數(shù),接著采用方法,將此模型問題轉(zhuǎn)化為一個線性代數(shù)方程組,從而轉(zhuǎn)化為求解方程組的系數(shù)。最后,通過我們可以得到近似解與真解的誤差估計以及收斂階,從而驗(yàn)證了應(yīng)用最低階元的混合有限元方法的正確性與準(zhǔn)確性。是什么意思?![]() ![]() 本文主要研究二階橢圓問題的混合有限元方法。首先,我們基于余能原理的變分形式,設(shè)中間變量,并引入空間及其范數(shù),導(dǎo)出此二階橢圓問題的混合模型。然后,應(yīng)用最低階的混合元,我們構(gòu)造網(wǎng)格上單元和邊的基函數(shù),接著采用方法,將此模型問題轉(zhuǎn)化為一個線性代數(shù)方程組,從而轉(zhuǎn)化為求解方程組的系數(shù)。最后,通過我們可以得到近似解與真解的誤差估計以及收斂階,從而驗(yàn)證了應(yīng)用最低階元的混合有限元方法的正確性與準(zhǔn)確性。
