Variational multi-scale finite element approximation of the compressible Navier-Stokes equations
(2016-03)
Article
Accés restringit per política de l'editorialPurpose - The purpose of this paper is to apply the variational multi-scale framework to the finite element approximation of the compressible Navier-Stokes equations written in conservation form. Even though this formulation ... -
Variational multiscale approximation of the one-dimensional forced Burgers equation: the role of orthogonal subgrid scales in turbulence modeling
(2018-02)
Article
Accés obertA numerical approximation for the one-dimensional Burgers equation is proposed by means of the orthogonal subgrid scales–variational multiscale (OSGS-VMS) method. We evaluate the role of the variational subscales in ... -
Variational multiscale based dissipation models for the estimation of atmospheric seeing
(Elsevier, 2015-01)
Article
Accés obertIn this work we present a numerical model for the estimation of atmospheric seeing in observation sites. The particularity of the method is that it is based on a Variational Multiscale turbulence model, its main feature ... -
Variational Multiscale error estimators for solid mechanics adaptive simulations: an Orthogonal Subgrid Scale approach
(2017-10)
Article
Accés obertIn this work we present a general error estimator for the finite element solution of solid mechanics problems based on the Variational Multiscale method. The main idea is to consider a rich model for the subgrid scales as ... -
Variational multiscale error estimators for the adaptive mesh refinement of compressible flow simulations
(2018-08)
Article
Accés obertThis article investigates an explicit a-posteriori error estimator for the finite element approximation of the compressible Navier–Stokes equations. The proposed methodology employs the Variational Multi-Scale framework, ... -
Weak imposition of essential boundary conditions in the finite element approximation of elliptic problems with non-matching meshes
(John Wiley & Sons, 2015-11)
Article
Accés obertIn this work, we propose a method to prescribe essential boundary conditions in the finite element approximation of elliptic problems when the boundary of the computational domain does not match with the element boundaries. ...
