A LOCAL MULTILEVEL PRECONDITIONER FOR THE ADAPTIVE MORTAR FINITE ELEMENT METHOD＊
《Journal of Computational Mathematics》2013年第5期532-548,共17页Feng Wang Jinru Chen 
In this paper, we propose a local multilevel preconditioner for the mortar finite element approximations of the elliptic problems. With some mesh assumptions on the interface, we prove that the condition number of the...

THE MORTAR ELEMENT METHOD FOR A NONLINEAR BIHARMONIC EQUATION被引量：2
《Journal of Computational Mathematics》2005年第5期537-560,共24页Shi, ZC Xu, XJ 
This work was subsidized by the special funds for major state basic research projects under 2005CB321700 and a grant from the National Science Foundation （NSF） of China （No. 10471144）.
The mortar element method is a new domain decomposition method（DDM） with nonoverlapping subdomains. It can handle the situation where the mesh on different subdomains need not align across interfaces, and the matchi...

CASCADIC MULTIGRID METHOD FOR THE MORTAR ELEMENT METHOD FOR P1 NONCONFORMING ELEMENT被引量：4
《Journal of Computational Mathematics》2005年第4期425-440,共16页Chun-jia Bi Dan-hui Hong 
Supported by the National Natural Science Foundation of China under grant 10071015.
In this paper, we consider the cascadic multigrid method for the mortar P1 nonconforming element which is used to solve the Poisson equation and prove that the cascadic conjugate gradient method is accurate with optim...

MORTAR FINITE VOLUME METHOD WITH ADINI ELEMENT FOR BIHARMONIC PROBLEM被引量：2
《Journal of Computational Mathematics》2004年第3期475-488,共14页Chun-jiaBi Li-kangLi 
In this paper, we construct and analyse a mortar finite volume method for the discretization for the biharmonic problem in R2. This method is based on the mortar-type Adini nonconforming finite element spaces. The opt...
MULTIGRID FOR THE MORTAR FINITE ELEMENT FOR PARABOLIC PROBLEM被引量：6
《Journal of Computational Mathematics》2003年第4期411-420,共10页Xue-junXu Jin-ruChen 
The research was supported by the Special Funds for Major State Basic Research Projects G1999032804 and a grant from LIAMA
In this paper, a mortar finite element method for parabolic problem is presented. Multi-grid method is used for solving the resulting discrete system. It is shown that the multigrid method is optimal, i.e, the converg...
