A posteriori goal-oriented bounds for the Poisson problem using potential and equilibrated flux reconstructions: Application to the hybridizable discontinuous Galerkin method
(2021-12-01)
Article
Accés obertWe present a general framework to compute upper and lower bounds for linear-functional outputs of the exact solutions of the Poisson equation based on reconstructions of the field variable and flux for both the primal and ... -
Building a certified reduced basis for coupled thermo-hydro-mechanical systems with goal-oriented error estimation
(Springer, 2020-09)
Article
Accés obertA goal-oriented a-posteriori error estimator is developed for transient coupled thermo-hydro-mechanical (THM) parametric problems solved with a reduced basis approximation. The estimator assesses the error in some specific ... -
Error assessment and mesh adaptivity for regularized continuous failure models
(2009-11-26)
Article
Accés obertThis paper deals with the adaptive finite element analysis of structural failure. A gradient-enhanced damage model has been chosen to simulate material degradation. Since this model is regularized in the post-peak regime, ... -
Subdomain-based flux-free a posteriori error estimators
(2006-01)
Article
Accés obertA new residual type flux-free error estimator is presented. It estimates upper and lower bounds of the error in energy norm. The proposed approach precludes the main drawbacks of standard residual type estimators, circumvents ...
