The bilinear finite element approximation for semi - singularly perturbed reaction - diffusion problems is considered 摘要考慮半奇異攝動反應(yīng)擴散問題的雙線性有限元逼近。
Anisotropic nonconforming finite element approximation to variational inequality problems with displacement obstacle 位移障礙下變分不等式問題的各向異性非協(xié)調(diào)有限元方法
The asymptotic expansions of the hermite finite element approximations for two point boundary value problem of fourth - order differential equations with extrapolation 有限元解的漸近展式與外推
Expanded mixed finite element approximations of the parabolic problems are considered . error estimates for the scalar unknwon , its gradient and its flux in l2 - norm are obtained for this new mixed formulation 通過數(shù)值分析進一步說明擴展混合元方法是穩(wěn)定的,并得到了未知函數(shù)、未知函數(shù)的梯度和流體流量的l ~ 2 -誤差估計。
In this thesis , we study ultraconvergence of finite element approximation in one dimensional case ( include two - point boundary value problem , one dimensional parabolic equation and parabolic type integro - differential equation ) 本文研究一維問題(包括兩點邊值問題,一維拋物問題及拋物型積分-微分方程)有限元逼近的強超收斂性。
