A correction adaptive two-grid finite element method for nonselfadjoint or indefinite elliptic problems
Fei Li, Qingguo Hong, Ming Tang +1
We propose, analyze, and numerically validate a correction adaptive two-grid finite element method (CAT-GFEM) for nonselfadjoint or indefinite elliptic problems. In contrast to the…
A BDDC method with an adaptive coarse space for three-dimensional advection-diffusion problems
Jie Peng, Shi Shu, Junxian Wang +1
The solution of nonsymmetric but positive definite (NSPD) systems arising from advection-diffusion problems is an important research topic in science and engineering. Balancing dom…
A Posteriori Error Estimates for A Modified Weak Galerkin Finite Element Method Solving Linear Elasticity Problems
Liu Chunmei, Zhong Liuqiang, Xie Yingying Xie +1
In this paper, a residual-type a posteriori error estimator is proposed and analyzed for a modified weak Galerkin finite element method solving linear elasticity problems. The esti…
A Posterior Error Estimator for Mixed Interior Penalty Discontinuous Galerkin Finite Element Method for the H(curl)-Elliptic Problems
Ming Tang, Xiaoqing Xing, Liuqiang Zhong
In this paper, we design the first residual type a posteriori error estimator for mixed interior penalty discontinuous Galerkin method for the H(curl)-elliptic problems. Then we pr…
Iterative two-level algorithm for nonsymmetric or indefinite elliptic problems
Ming Tang, Xiaoqing Xing, Ying Yang +1
In this paper, a new iterative two-level algorithm is presented for solving the finite element discretization for nonsymmetric or indefinite elliptic problems. The iterative two-le…
An iterative two-grid method for strongly nonlinear elliptic boundary value problems
Jiajun Zhan, Lei Yang, Xiaoqing Xing +1
We design and analyze an iterative two-grid algorithm for the finite element discretizations of strongly nonlinear elliptic boundary value problems in this paper. We propose an ite…
