Adaptive Solution of a Singularly-Perturbed Convection-Diffusion Problem Using a Stabilized Mixed Finite Element Method
Gonzalez, M.; Strugaru, M.
(2019-01-05)
We explore the applicability of a new adaptive stabilized dual-mixedfinite element method to a singularly-perturbed convection-diffusion equation withmixed boundary conditions. We establish the rate of convergence when the ... -
Low cost a posteriori error estimators for an augmented mixed FEM in linear elasticity. Dedicated to Professor Rodolfo Rodríguez on the occasion of his 60th birthday.
(2014-12-31)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 ... -
A posteriori error analysis of a stabilized mixed FEM for convectuion-diffusion problems
(2015-12-31)We present an augmented dual-mixed variational formulation for a linear convection-diffusion equation with homogeneous Dirichlet boundary conditions. The approach is based on the addition of suitable least squares type ... -
A posteriori error analysis of an augmented mixed finite element method for Darcy flow
(2015-12-31)We develop an a posteriori error analysis of residual type of a stabilized mixed finite element method for Darcy flow. The stabilized formulation is obtained by adding to the standard dual-mixed approach suitable residual ... -
Stabilization and a posteriori error analysis of a mixed FEM for convection–diffusion problems with mixed boundary conditions
Gonzalez, M.; Strugaru, M. (2020-06-02)
We introduce a new augmented dual-mixed finite element method for the linear convection-diffusion equation with mixed boundary conditions. The approach is based on adding suitable residual type terms to a dual-mixed ... -
Stabilized dual-mixed method for the problem of linear elasticity with mixed boundary conditions
(2014-12-31)We extend the applicability of the augmented dual-mixed method introduced recently in Gatica (2007), Gatica et al. (2009) to the problem of linear elasticity with mixed boundary conditions. The method is based on the ...
