A posteriori error analysis of an augmented dual-mixed method in linear elasticity with mixed boundary conditions
(2019-08)We consider the augmented mixed finite element method introduced in [7] for the equations of plane linear elasticity with mixed boundary conditions. We develop an a posteriori error analysis based on the Ritz projection ... -
A stabilized mixed method applied to Stokes system with nonhomogeneous source terms: The stationary case Dedicated to Prof. R. Rodríguez, on the occasion of his 65th birthday
(2020-06)This article is concerned with the Stokes system with nonhomogeneous source terms and nonhomogeneous Dirichlet boundary condition. First, we reformulate the problem in its dual mixed form, and then, we study its corresponding ... -
An a posteriori error analysis of a velocity-pseudostress formulation of the generalized Stokes problem
(2019-03-05)We consider a stabilized mixed finite element method introduced recently for the generalized Stokes problem. The method is obtained by adding suitable least squares terms to the dual-mixed variational formulation of the ... -
An a posteriori error analysis of an augmented discontinuous Galerkin formulation for Darcy flow
(2015)In this paper we develop an a posteriori error analysis for an augmented discontinuous Garlerkin formulation applied to the Darcy flow. More precisely, we derive a reliable and efficient a posteriori error estimator, ... -
An adaptive residual local projection finite element method for the navier–stokes equations
(2014)This work proposes and analyses an adaptive finite element scheme for the fully non-linear incompressible Navier-Stokes equations. A residual a posteriori error estimator is shown to be effective and reliable with respect ... -
An adaptive stabilized finite element scheme for a water quality model
(2007)Residual type a posteriori error estimators are introduced in this paper for an advection–diffusion–reaction problem with a Dirac delta source term. The error is measured in an adequately weighted W1,pW1,p-norm. These ... -
An augmented mixed finite element method with Lagrange multipliers: A priori and a posteriori error analyses
(2007)In this paper, we provide a priori and a posteriori error analyses of an augmented mixed finite element method with Lagrange multipliers applied to elliptic equations in divergence form with mixed boundary conditions. The ... -
Error estimators for advection–reaction–diffusion equations based on the solution of local problems
(2007)This paper deals with a posteriori error estimates for advection–reaction–diffusion equations. In particular, error estimators based on the solution of local problems are derived for a stabilized finite element method. ... -
Low cost a posteriori error estimators for an augmented mixed FEM in linear elasticity
(2014)We consider an augmented mixed finite element method applied to the linear elasticity problem and derive a posteriori error estimators that are simpler and easier to implement than the ones available in the literature. In ... -
New a posteriori error estimator for an stabilized mixed method applied to incompressible fluid flows
(2019-06-15)We consider an augmented mixed finite element method for incompressible fluid flows and develop a simple a posteriori error analysis. We obtain an a posteriori error estimator that is reliable and locally efficient. We ... -
On an adaptive stabilized mixed finite element method for the Oseen problem with mixed boundary conditions
(2020-06)We consider the Oseen problem with nonhomogeneous Dirichlet boundary conditions on a part of the boundary and a Neumann type boundary condition on the remaining part. Suitable least squares terms that arise from the ...
