Superconvergence of the Derivative Patch Recovery Technique and a Posteriori Error Estimation
نویسنده
چکیده
The derivative patch recovery technique developed by Zienkiewicz and Zhu 1]-3] for the nite element method is analyzed. It is shown that, for one dimensional problems and two dimensional problems using tensor product elements, the patch recovery technique yields superconvergence recovery for the derivatives. Consequently, the error estimator based on the recovered derivative is asymptotically exact.

SUMMARY This is the second in a series of two papers in which the patch recovery technique proposed by Zienkiewicz and Zhu 1]-3] is analyzed. In the rst paper 4], we have shown that the recovered derivative by the least squares tting is superconvergent for the two point boundary value problems. In the present work, we consider the two dimensional case in which the tensor product elements are us...
متن کاملGlobal Superconvergence for Optimal Control Problems Governed by Stokes Equations
In this paper, the global superconvergence analysis for the finite element approximation of the distributed optimal control governed by Stokes equations is discussed. For the control, a global superconvergence result is derived by applying patch recovery technique. For the state and the co-state, the global superconvergence results are derived by applying some postprocessing techniques for the ...
متن کاملValidation of the Quality of the A Posteriori Error Estimator Based on Polynomial Preserving Recovery for Linear Elements
In this paper the quality of the error estimator based on the Polynomial Preserving Recovery (PPR) is investigated using the computer-based approach described in [1, 3]. Also, a comparison is made between the performance of the error estimator based on the PPR and the one based on the Superconvergence Patch Recovery (SPR).
متن کاملThe Patch Recovery for Finite Element Approximation of Elasticity Problems under Quadrilateral Meshes
In this paper, some patch recovery methods are proposed and analyzed for finite element approximation of elasticity problems using quadrilateral meshes. Under a mild mesh condition, superconvergence results are established for the recovered stress tensors. Consequently, a posteriori error estimators based on the recovered stress tensors are asymptotically exact.
