Pseudo-Hyperbolic Equation Nonconforming H1-Galerkin Mixed Finite Element Error Estimate
2013/1/30
Based on H1-Galerkin mixed finite element method with nonconforming quasi-Wilson element, a numerical approximate scheme is established for pseudo-hyperbolic equations under arbitrary quadrilateral me...

2011/9/1
Abstract: In this paper, we present a multigrid preconditioner for solving the linear system arising from the piecewise linear nonconforming Crouzeix-Raviart discretization of second order elliptic pr...
A Posteriori Error Estimates for Nonconforming Approximations of Evolutionary Convection-Diffusion Problems
a posteriori error estimates time-nonconforming approximations convection-diffusion
2011/2/25
We derive computable upper bounds for the difference between an exact solution of the evolutionary convection-diffusion problem and an approximation of this solution.
The main aim of this paper is to study the error estimates of a nonconforming finite element with some superconvergence results under anisotropic meshes. The anisotropic interpolation error and consis...
A NONCONFORMING ANISOTROPIC FINITE ELEMENT APPROXIMATION WITH MOVING GRIDS FOR STOKES PROBLEM
Stokes problem Nonconforming finite element Anisotrop Moving grids Error estimate

This paper is devoted to the five parameters nonconforming finite
element schemes with
moving grids for velocity-pressure mixed formulations of the nonstationary
Stokes problem in 2-D. We show that...
Two Nonconforming Quadrilateral Elements for the Reissner-Mindlin Plate
Locking-free Quadrilateral nonconforming rotated Q1 element Reissner-Mindlin Plate
2012/8/1
We construct two low order nonconforming quadrilateral elements for the Reissner-Mindlin plate. The rst one consists of a modi ed nonconforming rotated Q1 element for one component of the rotation an...
The Nonconforming Finite Element Method for Signorini Problem
nonconforming finite element Signorini problem
2012/7/31
We present the linear nonconforming nite element approximation of the variational inequality resulting from Signorini problem. We show if the displacement eld is of H2 regularity,the convergence rat...
