Superconvergence Phenomena on Three-dimensional Meshes
نویسنده
چکیده
We give an overview of superconvergence phenomena in the finite element method for solving three-dimensional problems, in particular, for elliptic boundary value problems of second order over uniform meshes. Some difficulties with superconvergence on tetrahedral meshes are presented as well. For a given positive integer m we prove that there is no tetrahedralization of R3 whose all edges are m-valent.

A Numerical Study of Uniform Superconvergence of Ldg Method for Solving Singularly Perturbed Problems
In this paper, we consider the local discontinuous Galerkin method (LDG) for solving singularly perturbed convection-diffusion problems in oneand two-dimensional settings. The existence and uniqueness of the LDG solutions are verified. Numerical experiments demonstrate that it seems impossible to obtain uniform superconvergence for numerical fluxes under uniform meshes. Thanks to the implementa...
متن کاملA New Superconvergence Property of Wilson Nonconforming Finite Element
In this paper the Wilson nonconforming nite element method is considered to solve the general two-dimensional second-order elliptic boundary value problems. A new superconvergence property at the vertices and the midpoints of four edges of rectangular meshes is obtained. The Wilson nonconforming nite element has been widely used in computational mechanics and structural engineering because of i...
متن کاملConvergence and Superconvergence of a Nonconforming Finite Element on Anisotropic Meshes
The main aim of this paper is to study the error estimates of a nonconforming finite element for general second order problems, in particular, the superconvergence properties under anisotropic meshes. Some extrapolation results on rectangular meshes are also discussed. Finally, numerical results are presented, which coincides with our theoretical analysis perfectly.
متن کاملSuperconvergence Analysis and Error Expansion for the Wilson Nonconforming Nite Element
In this paper the Wilson nonconforming nite element is considered for solving a class of two-dimensional second-order elliptic boundary value problems. Superconvergence estimates and error expansions are obtained for both uniform and non-uniform rectangular meshes. A new lower bound of the error shows that the usual error estimates are optimal. Finally a discussion on the error behaviour in neg...
متن کاملSupercloseness and superconvergence of stabilized low-order finite element discretizations of the Stokes Problem
The supercloseness and superconvergence property of stabilized finite element methods applied to the Stokes problem are studied. We consider consistent residual based stabilization methods as well as nonconsistent local projection type stabilizations. Moreover, we are able to show the supercloseness of the linear part of the MINI-element solution which has been previously observed in practical ...
