    In this work we put the method proposed by van Hinsberg et al. [29] to the test, highlighting its accuracy and efficiency in a sequence of benchmarks of increasing complexity. Furthermore, we explore the possibility of ...
  • Estudi d'alternatives per a la millora funcional del dic de recer del Port Olímpic 

    Casas González, Guillermo (Universitat Politècnica de Catalunya, 2010-05-10)
    Minor thesis
    Open Access
    El Puerto Olímpico de Barcelona ha sufrido importantes daños en varios episodios de temporal desde su inauguración, en 1992. Estos daños han sido causados por los elevados caudales de rebase que se han dado sobre el dique ...
  • Lagrangian analysis of multiscale particulate flows with the particle finite element method 

    Oñate Ibáñez de Navarra, Eugenio; Celigueta Jordana, Miguel Ángel; Latorre Sánchez, Juan Salvador; Casas González, Guillermo; Rossi, Riccardo; Rojek, Jerzy (Springer, 2014-05)
    Article
    Open Access
    We present a Lagrangian numerical technique for the analysis of flows incorporating physical particles of different sizes. The numerical approach is based on the particle finite element method (PFEM) which blends concepts ...
  • Numerical analysis of particle-laden flows with the finite element method 

    Casas González, Guillermo (Universitat Politècnica de Catalunya, 2018-10-30)
    Doctoral thesis
    Open Access
    In this work we study the numerical simulation of particle-laden fluids, with a focus on Newtonian fluids and spherical, rigid particles. We are thus dealing with a multi-phase (more precisely, a multi-component) problem, ...
  • PFEM–DEM for particle-laden flows with free surface 

    Franci, Alessandro; Pouplana Sarda, Ignasi de; Casas González, Guillermo; Celigueta Jordana, Miguel Ángel; González Usúa, Joaquín; Oñate Ibáñez de Navarra, Eugenio (Springer, 2019-05)
    Article

    This work proposes a fully Lagrangian formulation for the numerical modeling of free-surface particle-laden flows. The fluid phase is solved using the particle finite element method (PFEM), while the solid particles embedded ...
