Star-Based a Posteriori Error Estimates for Elliptic Problems
We give an a posteriori error estimator for nonconforming finite element approximations of diffusionreaction and Stokes problems, which relies on the solution of local problems on stars. It is proved to be equivalent to the energy error up to a data oscillation, without requiring Helmholtz decomposition of the error nor saturation assumption. Numerical experiments illustrate the good behavior a...
متن کاملElliptic Reconstruction and a Posteriori Error Estimates for Parabolic Problems
It is known that the energy technique for a posteriori error analysis of finite element discretizations of parabolic problems yields suboptimal rates in the norm L∞(0, T ; L2(Ω)). In this paper we combine energy techniques with an appropriate pointwise representation of the error based on an elliptic reconstruction operator which restores the optimal order (and regularity for piecewise polynomi...

متن کاملA posteriori error estimates for nonlinear problems. Lr-estimates for finite element discretizations of elliptic equations
— We extend the gênerai framework of [18] for deriving a posteriori error estimâtes for approximate solutions of noniinear elliptic problems such ihat it also yields L'-error estimâtes. The gênerai results are applied to finite element discretizations of scalar quasilinear elliptic pdes of 2nd order and the stationary incompressible Navier-Stokes équations. They immediately yield a posteriori e...
متن کاملA Posteriori Error Estimates for Elliptic Variational Inequalities
We derive hierarchical a posteriori error estimates for elliptic variational inequalities. The evaluation amounts to the solution of corresponding scalar local subproblems. We derive some upper bounds for the e ectivity rates and the numerical properties are illustrated by typical examples.
