    • A simple shock-capturing technique for high-order discontinuous Galerkin methods 

      Huerta, Antonio; Casoni Rero, Eva; Peraire Guitart, Jaume (2012-08)
      Article
      Open Access
      This article presents a novel shock-capturing technique for the discontinuous Galerkin (DG) method. The technique is designed for compressible flow problems, which are usually characterized by the presence of strong shocks ...
    • Alya: Computational Solid Mechanics for Supercomputers 

      Casoni Rero, Eva; Jérusalem, Antoine; Samaniego, Cristóbal; Eguzkitza, Beatriz; Lafortune, Pierre; Tjahjanto, Denny; Sáez, Xavier; Houzeaux, Guillaume; Vázquez, Mariano (Springer, 2014-08-13)
      Article
      Open Access
      While solid mechanics codes are now conventional tools both in industry and research, the increasingly more exigent requirements of both sectors are fuelling the need for more computational power and more advanced algorithms. ...
    • An XFEM/CZM implementation for massively parallel simulations of composites fracture 

      Vigueras, Guillermo; Sket, Federico; Samaniego, Cristobal; Wu, Ling; Noels, Ludovic; Tjahjanto, Denny; Casoni Rero, Eva; Houzeaux, Guillaume; Makradi, Ahmed; Molina-Aldareguia, Jon M.; Vázquez, Mariano; Jérusalem, Antoine (Elsevier, 2015-07)
      Article
      Open Access
      Because of their widely generalized use in many industries, composites are the subject of many research campaigns. More particularly, the development of both accurate and flexible numerical models able to capture their ...
    • Dimensionless analysis of HSDM and application to simulation of breakthrough curves of highly adsorbent porous media 

      Pérez Foguet, Agustí; Casoni Rero, Eva; Huerta, Antonio (2013-05)
      Article
      Open Access
      The homogeneous surface diffusion model (HSDM) is widely used for adsorption modeling of aqueous solutions. The Biot number is usually used to characterize model behavior. However, some limitations of this characterization ...
    • One-dimensional shock-capturing for high-order discontinuous Galerkin methods 

      Casoni Rero, Eva; Peraire Guitart, Jaume; Huerta, Antonio (2012-02)
      Article
      Open Access
      Discontinuous Galerkin methods have emerged in recent years as an alternative for nonlinear conservation equations. In particular, their inherent structure (a numerical flux based on a suitable approximate Riemann solver ...
    • Shock capturing for discontinuous Galerkin methods 

      Casoni Rero, Eva; Huerta, Antonio (2009-04-23T10:42:49Z)
      Conference report
      Open Access
      This work is devoted to solve scalar hyperbolic conservation laws in the presence of strong shocks with discontinuous Galerkin methods (DGM). A standard approach is to use limiting strategies in order to avoid oscillations ...
    • Shock capturing for discontinuous galerkin methods 

      Casoni Rero, Eva (Universitat Politècnica de Catalunya, 2011-10-14)
      Doctoral thesis
      Open Access
      Aquesta tesi doctoral proposa formulacions de Galerkin Discontinu (DG) d’alt ordre per la captura de shocks, obtenint alhora solucions altament precises per problemes de flux compressible. En les últimes dècades, la ...
    • Shock-capturing with discontinuous garlekin methods 

      Huerta, Antonio; Casoni Rero, Eva (2009-06-08T08:32:41Z)
      Conference report
      Open Access
      A shock capturing strategy for high order Discontinuous Galerkin methods for conservation laws is proposed. We present a method in the one-dimensional case based on the introduction of artificial viscosity into the ...
    • Un método de captura de choques basado en las funciones de forma para Galerkin discontinuo de alto orden 

      Casoni Rero, Eva; Peraire Guitart, Jaume; Huerta, Antonio (2012)
      Article
      Open Access
      En este artículo se presenta un método de alto orden de Galerkin discontinuo para problemas de flujo com- presible, en los cuales es muy frecuente la aparición de choques. La estabilización se introduce mediante una nueva ...
