Accurate upper and lower error bounds by solving flux-free local problems in
(2004-12)
Article
Accés obertTwo implicit residual type estimators yielding upper bounds of the error are presented which do not require flux equilibration. One of them is based on the ideas introduced in [MAC 00, CAR 99, MOR 03, PRU 02]. The new ... -
Adaptivity based on error estimation for viscoplastic softening materials
(2000-02)
Article
Accés obertThis paper focuses on the numerical simulation of strain softening mechanical problems. Two problems arise: (1) the constitutive model has to be regular and (2) the numerical technique must be able to capture the two scales ... -

Error estimation and adaptivity for nonlinear FE analysis
(2002-03)
Article
Accés obertAn adaptive strategy for nonlinear finite-element analysis, based on the combination of error estimation and h-remeshing, is presented. Its two main ingredients are a residual-type error estimator and an unstructured ... -

Error estimation for proper generalized decomposition solutions: dual analysis and adaptivity for quantities of interest
(2021-02-15)
Article
Accés obertWhen designing a structure or engineering a component, it is crucial to use methods that provide fast and reliable solutions, so that a large number of design options can be assessed. In this context, the proper generalized ... -
Error estimation in vibroacoustic problems solved by means of finite elements
(2010-06)
Text en actes de congrés
Accés obertThe vibroacoustic equations can be solved by means of the finite element method. A discretisation of the structure and the acoustic domains is required and highly influences the quality of the numerical solution. There ... -
Goal oriented error estimation for the element free Galerkin method
(2007-06)
Article
Accés obertA novel approach for implicit residual-type error estimation in meshfree methods is presented. This allows to compute upper and lower bounds of the error in energy norm with the ultimate goal of obtaining bounds for outputs ... -
Hybridizable discontinuous Galerkin p-adaptivity for wave propagation problems
(2013)
Article
Accés obertA p-adaptive hybridizable discontinuous Galerkin method for the solution of wave problems is presented in a challenging engineering problem. Moreover, its performance is compared with a high-order continuous Galerkin. The ...
