Multi-mesh Adaptive Finite Element Algorithms for Constrained Optimal Control Problems Governed By Semi-Linear Parabolic Equations
收藏 引用
Acta Mathematicae Applicatae Sinica 2014年 第2期30卷 411-428页
作者: Tie-jun CHEN Jian-xin XIAO Hui-ying WANG Medical College of Yiyang
In this paper, we derive a posteriori error estimators for the constrained optimal control problems governed by semi-linear parabolic equations under some assumptions. Then we use them to construct reliable and effici... 详细信息

Adaptive Finite Element Method for Steady Convection-Diffusion Equation
收藏 引用
American Journal of Computational Mathematics 2016年 第3期6卷 275-285页
作者: Gelaw Temesgen Mekuria Jakkula Anand Rao Department of Mathematics Mizan Tepi University Mizan Teferi Ethiopia Department of Mathematics Osmania University Hyderabad India
This paper examines the numerical solution of the convection-diffusion equation in 2-D. The solution of this equation possesses singularities in the form of boundary or interior layers due to non-smooth boundary condi... 详细信息
