    • A FEM-DEM technique for studying the motion of particles in non-Newtonian fluids: application to the transport of drill cuttings in wellbores 

      Celigueta Jordana, Miguel Ángel; Deshpande, Kedar M.; Latorre, Salvador; Oñate Ibáñez de Navarra, Eugenio (Springer, 2015-11)
      Article
      Open Access
      We present a procedure for coupling the finite element method (FEM) and the discrete element method (DEM) for analysis of the motion of particles in non-Newtonian fluids. Particles are assumed to be spherical and immersed ...
    • A prototype of a micro-scale model for the distribution of NO2 in urban areas 

      Pouplana Sarda, Ignasi de; Latorre, Salvador; Maso Sotomayor, Miguel; Guinart, Xavier; Oñate Ibáñez de Navarra, Eugenio; Perez Gabucio, Eva; Hernández Cardona, Isabel; Baulies Bochaca, Xavier (2023-02)

      We present a new 2.5D model for predicting the concentration of nitrogen dioxide (NO2) at street level in an urban area. This work develops the first prototype of a tool that should provide fast quantitative answers ...
    • Advances in the DEM and coupled DEM and FEM techniques in non linear solid mechanics 

      Oñate Ibáñez de Navarra, Eugenio; Zárate Araiza, José Francisco; Celigueta Jordana, Miguel Ángel; Miquel Canet, Juan; Carbonell, J.M.; Arrufat Garcia, Ferran; Latorre, Salvador; Santasusana Isach, Miquel; González Lopez, Jose Manuel (2017-05)
      Research report

      Abstract In this chapter we present recent advances in the Discrete Element Method (DEM) and in the coupling of the DEM with the Finite Element Method (FEM) for solving a variety of problems in non linear solid mechanics ...
    • Design and validation of rockfall protection systems by numerical modeling with discrete elements 

      Latorre, Salvador; Celigueta Jordana, Miguel Ángel; Irazábal González, Joaquín; Salazar González, Fernando; Oñate Ibáñez de Navarra, Eugenio (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
      Conference report
      Open Access
      Rockfall protection systems are installed in order to preserve civil infrastructures against landslides and falling rocks. For the evaluation of these systems,one of the main problems is the difficulty to develop laboratory ...
    • PFEM application in fluid structure interaction problems 

      Celigueta Jordana, Miguel Ángel; Larese De Tetto, Antonia; Latorre, Salvador (CIMNE (Centro Internacional de Métodos Numéricos en Ingeniería), 2008)
      Conference report
      Open Access
      In the current paper the Particle Finite Element Method (PFEM), an innovative numerical method for solving a wide spectrum of problems involving the interaction of fluid and structures, is briefly presented. Many examples ...
    • Possibilities of the particle finite element method in computational mechanics 

      Oñate Ibáñez de Navarra, Eugenio; Idelsohn Barg, Sergio Rodolfo; Celigueta Jordana, Miguel Ángel; Rossi, Riccardo; Latorre, Salvador (2010)
      Research report
      Open Access
      We present some developments in the formulation of the Particle Finite Element Method (PFEM) for analysis of complex coupled problems in fluid and solid mechanics accounting for fluid-structure interaction and coupled ...
