Mixed finite element methods with convection stabilization for the large eddy simulation of incompressible turbulent flows
Colomés Gené, Oriol; Badia, Santiago; Principe, Ricardo Javier (2016-06)
Article
Accés obertThe variational multiscale method thought as an implicit large eddy simulation model for turbulent flows has been shown to be an alternative to the widely used physical-based models. This method is traditionally combined ... -
Multilevel balancing domain decomposition at extreme scales
Badia, Santiago; Martín Huertas, Alberto Francisco; Principe, Ricardo Javier (2016-01-01)
Article
Accés obert© 2016 Society for Industrial and Applied Mathematics. In this paper we present a fully distributed, communicator-aware, recursive, and interlevel-overlapped message-passing implementation of the multilevel balancing domain ... -
On the approximation of the subgrid scale for systems of equations
Principe, Ricardo Javier; Codina, Ramon (2008)
Ressenya

On the scalability of inexact balancing domain decomposition by constraints with overlapped coarse/fine corrections
Badia, Santiago; Martín Huertas, Alberto Francisco; Principe, Ricardo Javier (2015-12)
Article
Accés obertIn this work, we analyze the scalability of inexact two-level balancing domain decomposition by constraints (BDDC) preconditioners for Krylov subspace iterative solvers, when using a highly scalable asynchronous parallel ... -
On the stabilization parameter in the subgrid scale approximation of scalar convection-diffusion-reaction equations on distorted meshes
Principe, Ricardo Javier; Codina, Ramon (2010-04-01)
Article
Accés restringit per política de l'editorialIn this paper we revisit the definition of the stabilization parameter in the finite element approximation of the convection–diffusion–reaction equation. The starting point is the decomposition of the unknown into its ... -
On the use of ensemble averaging techniques to accelerate the Uncertainty Quantification of CFD predictions in wind engineering
Tosi, Riccardo; Núñez Corbacho, Marc; Pons Prats, Jordi; Principe, Ricardo Javier; Rossi, Riccardo (2022-09)
Article
Accés obertIn this work we focus on reducing the wall clock time required to compute statistical estimators of highly chaotic incompressible flows on high performance computing systems. Our approach consists of replacing a single ... -
Spatial approximation of the radiation transport equation using a two-scale finite element method
Ávila, Matías; Codina, Ramon; Principe, Ricardo Javier (2009-08-11)
Article
Accés obertIn this paper we present stabilized finite element methods to discretize in space the monochromatic radiation transport equation. These methods are based on the decomposition of the unknowns into resolvable and subgrid ... -
The dissipative structure of variational multiscale methods for incompressible flows
Principe, Ricardo Javier; Codina, Ramon; Henke, Florian (2010-02-01)
Article
Accés restringit per política de l'editorialIn this paper, we present a precise definition of the numerical dissipation for the orthogonal projection version of the variational multiscale method for incompressible flows. We show that, only if the space of subscales ...
