  • A 3D-1D cardiac-vascular computational feedbacked model 

    Santiago, Alfonso; Vázquez, Mariano; Houzeaux, Guillaume; Aguado-Sierra, Jazmin; López, Mariña; Rivero, Matías; Blanco Sánchez, Pablo; Watanabe, Sansuke (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    A first version of a cardiovascular coupled model is presented. The modelling tools are Alya, the BSC tool for biomechanical simulations; and ADAN55, the LNCC model of the arterial blood flow. The former solves the ...
  • A Geometrical Domain Decomposition Methods in Computational Fluid Dynamics 

    Houzeaux, Guillaume (Universitat Politècnica de Catalunya, 2002-05-10)
    Doctoral thesis
  • A parallel coupled algorithm for the solution of deformable two-body contact problem 

    Rivero Almeida, José Miguel; Cajas, J.C.; Houzeaux, Guillaume; Vázquez, Mariano (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    This work presents a parallel iterative method for numerical solving frictionless contact problem for two elastic bodies. Each iterative step consists of a Dirichlet problem for the one body and a Neumann problem for ...
  • A variational multiscale stabilized finite element method for the solution of the Euler equations of nonhydrostatic stratified flows 

    Marras, Simone; Moragues, Margarida; Vázquez, Mariano; Jorba Casellas, Oriol; Houzeaux, Guillaume (2013-03-01)
    Article
    Restricted access - publisher's policy
    We present a compressible version of the variational multiscale stabilization (VMS) method applied to the finite element (FE) solution of the Euler equations for nonhydrostatic stratified flows. This paper is meant to ...
  • An unstructured CFD approach for numerical weather prediction 

    Aubry, Romain; Vázquez, Mariano; Houzeaux, Guillaume; Cela Espín, José M.; Marras, Simone (2010)
    Conference report
    Restricted access - publisher's policy
    The aim of this paper is twofold. First, it is difficult for a newcomer in the Numerical Weather Prediction (NWP) community to find similarities with Computational Fluid Dynamics (CFD) techniques as far as the numerical ...
  • Application of a Galerkin finite element scheme to atmospheric buoyant and gravity driven flows 

    Marras, Simone; Vázquez, Mariano; Jorba Casellas, Oriol; Aubry, Romain; Houzeaux, Guillaume; Baldasano Recio, José María (2010)
    Conference report
    Restricted access - publisher's policy
    The application of a new finite element (FE) technique for the solution of stratified, non-hydrostatic, low-Mach number flows is introduced in the context of mesoscale atmospheric modeling. In this framework, a Compressible ...
  • Coupled electromechanical model of the heart: Parallel finite element formulation 

    Lafortune, Pierre; Aris, Ruth; Vázquez, Mariano; Houzeaux, Guillaume (2012-01)
    Article
    Restricted access - publisher's policy
    In this paper, a highly parallel coupled electromechanical model of the heart is presented and assessed. The parallel-coupled model is thoroughly discussed, with scalability proven up to hundreds of cores. This work focuses ...
  • Simulations of moist convection by a variational multiscale stabilized finite element method 

    Marras, Simone; Moragues, Margarida; Vázquez, Mariano; Jorba Casellas, Oriol; Houzeaux, Guillaume (2013-11-01)
    Article
    Restricted access - publisher's policy
    A variational multiscale stabilized finite element scheme is presented for the solution of moist atmospheric flows. The fully compressible Euler equations are coupled to a system of three advection equations that model the ...
  • The Fixed-Mesh ALE approach for the numerical approximation of flows in moving domains 

    Codina, Ramon; Houzeaux, Guillaume; Coppola Owen, Ángel H.; Baiges Aznar, Joan (2008-07-30)
    Article
    Open Access
    In this paper we propose a method to approximate flow problems in moving domains using always a given grid for the spatial discretization, and therefore the formulation to be presented falls within the category of ...
