An algorithm for mesh refinement and un-refinement in fast transient dynamics
Casadei, Folco; Díez, Pedro; Verdugo Rojano, Francesc (2013-08)
Article
Accés obertA procedure to locally refine and un-refine an unstructured computational grid of four-node quadrilaterals (in 2D) or of eight-node hexahedra (in 3D) is presented. The chosen refinement strategy generates only elements of ... -
Computable bounds of functional outputs in linear visco-elastodynamics
Verdugo Rojano, Francesc; Díez, Pedro (2012)
Article
Accés obertThis work presents a new technique yielding computable bounds of quantities of interest in the framework of linear visco-elastodynamics. A novel expression for the error representation is introduced, alternative to the ... -

Error assessment and adaptivity for structural transient dynamics
Verdugo Rojano, Francesc (Universitat Politècnica de Catalunya, 2013-10-15)
Tesi
Accés obertThe finite element method is a valuable tool for simulating complex physical phenomena. However, any finite element based simulation has an intrinsic amount of error with respect to the exact solution of the selected ... -
Error assessment in structural transient dynamics
Verdugo Rojano, Francesc; Parés Mariné, Núria; Díez, Pedro (2014-03-01)
Article
Accés obertThis paper presents in a unified framework the most representative state-of-the-art techniques on a posteriori error assessment for second order hyperbolic problems, i.e., structural transient dynamics. For the sake of ... -
Geometrical discretisations for unfitted finite elements on explicit boundary representations
Badia, Santiago; Martorell Pol, Pere Antoni; Verdugo Rojano, Francesc (2022-07-01)
Article
Accés restringit per política de l'editorialUnfitted (also known as embedded or immersed) finite element approximations of partial differential equations are very attractive because they have much lower geometrical requirements than standard body-fitted formulations. ... -
Goal-oriented space-time adaptivity for transient dynamics using a modal description of the adjoint solution
Verdugo Rojano, Francesc; Parés Mariné, Núria; Díez, Pedro (2014-08-01)
Article
Accés obertThis article presents a space-time adaptive strategy for transient elastodynamics. The method aims at computing an optimal space-time discretization such that the computed solution has an error in the quantity of interest ... -
Mixed aggregated finite element methods for the unfitted discretization of the Stokes problem
Badia, Santiago; Martín Huertas, Alberto Francisco; Verdugo Rojano, Francesc (2018-12-18)
Article
Accés obertIn this work, we consider unfitted finite element methods for the numerical approximation of the Stokes problem. It is well-known that these kinds of methods lead to arbitrarily ill-conditioned systems and poorly approximated ... -
Modal-based goal-oriented error assessment and adaptivity for structural dynamics
Verdugo Rojano, Francesc; Parés Mariné, Núria; Díez, Pedro (2014)
Text en actes de congrés
Accés obert -
Modal-based goal-oriented error assessment for timeline-dependent quantities in transient dynamics
Verdugo Rojano, Francesc; Parés Mariné, Núria; Díez, Pedro (John Wiley & Sons, 2013-08-24)
Article
Accés restringit per política de l'editorialThis article presents a new approach to assess the error in specific quantities of interest in the framework of linear elastodynamics. In particular, a new type of quantities of interest (referred as timeline-dependent ... -
Modelització numèrica de la propagació d'onatge en zones costaneres mitjançant el mètode Galerkin discontinu
Verdugo Rojano, Francesc (Universitat Politècnica de Catalunya, 2009-07-03)
Tesina
Accés obertL'objectiu d'aquesta tesina és desenvolupar una eina eficient per a la modelització de la propagació d'onatge en zones costaneres. Aquest és un problema complex per diversos aspectes: grans requeriments de càlcul -necessaris ... -
Robust and scalable domain decomposition solvers for unfitted finite element methods
Badia, Santiago; Verdugo Rojano, Francesc (2018-12)
Article
Accés obertUnfitted finite element methods, e.g., extended finite element techniques or the so-called finite cell method, have a great potential for large scale simulations, since they avoid the generation of body-fitted meshes and ... -
The aggregated unfitted finite element method for elliptic problems
Badia, Santiago; Verdugo Rojano, Francesc; Martín Huertas, Alberto Francisco (2018-07)
Article
Accés obertUnfitted finite element techniques are valuable tools in different applications where the generation of body-fitted meshes is difficult. However, these techniques are prone to severe ill conditioning problems that obstruct ...
