    Article
    Open Access
    Buildair S.A. has designed, manufactured and built an inflatable hangar (called hangar H75) for the aeronautical industry at Jeddah Airport, Kingdom of Saudi Arabia. H75 is the largest air-cell inflated structure ever built ...

  • Adaptive breakwaters with inflatable elements for coastal protection. Preliminary numerical estimation of their performance 

    Ryzhakov, Pavel; Hermosilla Casajús, Pedro; Ubach Fuentes, Pere-Andreu; Oñate Ibáñez de Navarra, Eugenio (2022-05)
    Article
    Open Access
    Excessive erosion of sand beaches defines a serious problem worldwide and is particularly pronounced in the Mediterranean region. One of the typical mea- sures for alleviating this erosion consists in building rigid ...

  • Semi-Lagrangian formulation for the advection–diffusion–absorption equation 

    Puigferrat Pérez, Albert; Maso Sotomayor, Miguel; Pouplana Sarda, Ignasi de; Casas González, Guillermo; Oñate Ibáñez de Navarra, Eugenio (2021-07)
    Article
    Open Access
    We present a numerical method for solving advective–diffusive–absorptive problems with high values of advection and absorption. A Lagrangian approach based on the updated version of the classical Particle Finite Element ...

  • Assessment of simplified momentum equations for free surface flows through rigid porous media 

    Düsterhöft Wriggers, Wibke; Larese De Tetto, Antonia; Oñate Ibáñez de Navarra, Eugenio; Rung, Thomas (Springer Nature, 2023-06)
    Article
    Open Access
    In many applications, free surface flow through rigid porous media has to be modeled. Examples refer to coastal engineering applications as well as geotechnical or biomedical applications. Albeit the frequent applications, ...

  • Numerical prediction of the distribution of black carbon in a street canyon using a semi-Lagrangian finite element formulation 

    Puigferrat Pérez, Albert; Pouplana Sarda, Ignasi de; Amato, Fulvio; Oñate Ibáñez de Navarra, Eugenio (Elsevier, 2021-07)
    Article
    Open Access
    We present a procedure for coupling the fluid and transport equations to model the distribution of a pollutant in a street canyon, in this case, black carbon (BC). The fluid flow is calculated with a stabilized finite ...

  • Numerical simulation of particle impact drilling (PID) systems: a one-way coupled approach 

    Casas González, Guillermo; Pouplana Sarda, Ignasi de; Gandikota, Varadaraju; Oñate Ibáñez de Navarra, Eugenio (Springer, 2022-07)
    Article
    Open Access
    A numerical technique based on a CFD-DEM method is presented for the analysis of particle impact drilling (PID) systems. The method is built from a preexisting finite element Navier–Stokes solver for the fluid phase and a ...

  • PFEM formulation for thermo-coupled FSI analysis: application to nuclear core melt accident 

    Franci, Alessandro; Oñate Ibáñez de Navarra, Eugenio; Carbonell Puigbó, Josep Maria; Chiumenti, Michele (2017-10)
    Article
    Open Access
    The aim of this paper is to present a Lagrangian formulation for thermo-coupled fluid–structure interaction (FSI) problems and to show its applicability to the simulation of hypothetical scenarios of a nuclear core melt ...

  • Novel seismic design solution for underground structures. Case study of a 2-story 3-bay subway station 

    Bu, Xiangbo; Ledesma Villalba, Alberto; López Almansa, Francisco (Elsevier, 2022-02)
    Article
    Open Access
    This paper proposes an innovative seismic design approach for shallow rectangular cut-and-cover underground subway or railway stations. The traditional approach is to design rigid frame-like structures by connecting rigidly ...

  • Factors influencing Safety on Construction Projects (fSCPs): types and categories 

    Muñoz La Rivera, Felipe; Mora Serrano, Javier; Oñate Ibáñez de Navarra, Eugenio (2021-10)
    Article
    Open Access
    Due to the fact of activity, environment and work dynamics, the construction industry is characterised by high accident rates. Different initiatives have emerged to reduce these figures, which focus on using new methodologies ...
