A posteriori error estimation of approximate boundary fluxes
نویسندگان
چکیده
This paper describes the a posteriori estimation of the error in the flux of a finite element approximation on a piece of the boundary of the domain. The estimate is obtained via a generalized Green’s function corresponding to the quantity of interest on the boundary. We investigate the effects of smoothing the data corresponding to the quantity of interest and explore the effective domain of dependence of the quantity. We relate this approach to previous work by M. F. Wheeler, G. F. Carey, I. Babuska et al., and M. Larson et al. Copyright q 2007 John Wiley & Sons, Ltd.

On a method for a-posteriori error estimation of approximate solutions to parabolic problems
The aim of the paper is to derive a method for the construction of a-posteriori error estimate to approximate solutions to parabolic initial-boundary value problems. The computation of the suggested error bound requires only the computation of a finite number of systems or linear algebraic equations. These systems can be solved parallelly. It is proved that the suggested a-posteriori error esti...
متن کاملA Posteriori Error Estimation for the Poisson Equation with Mixed Dirichlet/Neumann Boundary Conditions
The present work is devoted to the a posteriori error estimation for the Poisson equation with mixed Dirichlet/Neumann boundary conditions. Using the duality technique we derive a reliable and efficient a posteriori error estimator that measures the error in the energy norm. The estimator can be used in assessing the error of any approximate solution which belongs to the Sobolev space H, indepe...
متن کاملA posteriori $ L^2(L^2)$-error estimates with the new version of streamline diffusion method for the wave equation
In this article, we study the new streamline diffusion finite element for treating the linear second order hyperbolic initial-boundary value problem. We prove a posteriori $ L^2(L^2)$ and error estimates for this method under minimal regularity hypothesis. Test problem of an application of the wave equation in the laser is presented to verify the efficiency and accuracy of the method.
متن کاملOn a Dimensional Reduction Method . III . A Posteriori Error Estimation and an Adaptive Approach
This paper is the last in a series of three which analyze an adaptive approximate approach for solving (n + l)-dimensional boundary value problems by replacing them with systems of equations in n-dimensional space. In this paper we show how to find reliable a posteriori estimates for the error and how these can also be used in the design of an adaptive strategy. Various numerical examples are c...
متن کاملSuperconvergence and a Posteriori Error Estimation for Triangular Mixed Nite Elements
In this paper,we prove superconvergence results for the vector variable when lowest order triangular mixed nite elements of Raviart-Thomas type 17] on uniform triangulations are used, i.e., that the H(div;)-distance between the approximate solution and a suitable projection of the real solution is of higher order than the H(div;)-error. We prove results for both Dirichlet and Neumann boundary c...
