  • Cool steam method for desalinating seawater 

    Arnau del Amo, Pedro Antonio; Navarro Navarro, Naeria; Soraluce Acebo, Javier; Martínez-Iglesias, José Maria; Illas, Jorge; Oñate Ibáñez de Navarra, Eugenio (2019-11)
    Article
    Open Access
    Cool steam is an innovative distillation technology based on low-temperature thermal distillation (LTTD), which allows obtaining fresh water from non-safe water sources with substantially low energy consumption. LTTD ...
  • A four-noded quadrilateral element for composite laminated plates/shell using the refined zigzag theory 

    Oñate Ibáñez de Navarra, Eugenio; Oller Martínez, Sergio Horacio (2012-06)
    External research report
    Open Access
    A new bilinear 4-noded quadrilateral element (called QLRZ) for the analysis of composite laminated and sandwich plates/shells based on the refined zigzag theory (RZT) proposed by Tessler et al. [1] is presented. The element ...
  • Modeling and simulation of the effect of blast loading on structures using and adaptive blending of discrete and finite element methods 

    Oñate Ibáñez de Navarra, Eugenio; Labra, C.; Zárate Araiza, José Francisco; Rojek, Jerzy (2011)

  • Reflexiones sobre el tránsito de la idea al producto en el entorno de la Escuela de Caminos de Barcelona 

    Oñate Ibáñez de Navarra, Eugenio (2011)
    External research report
    Open Access
    Se presentan unas reflexiones sobre el ciclo que las ideas recorren desde que surgen en un entorno universitario hasta que se transforman en un producto industrial. Se concretan estas reflexiones en el contexto de la Escuela ...
  • The cycle of ideas in research development and technology transfer 

    Oñate Ibáñez de Navarra, Eugenio (2011)
    External research report
    Open Access
    When people talks about research, development and technology transfer (RTD in short) and commercial industrial activities, it is quite usual to mix up objectives, resources and responsibilities. There is a growing opinion, ...
  • Explicit dynamic analysis of thin membrane structures 

    Flores Le Roux, Roberto Maurice; Ortega, Enrique; Oñate Ibáñez de Navarra, Eugenio (2011-02)
    External research report
    Open Access
    An explicit dynamic structural solver developed at CIMNE for the analysis of parachutes is presented. The canopy fabric has a negligible out-of-plane stiffness, therefore its numerical study presents important challenges. ...
  • El ciclo de las ideas en la I+D+i 

    Oñate Ibáñez de Navarra, Eugenio (2011-03)
    External research report
    Open Access
    Cuando se habla de la investigación, el desarrollo tecnológico y la innovación (I+D+I en siglas, que yo escribo todas en mayúsculas [1]) es frecuente confundir fines, medios y responsabilidades. La última moda parece que ...
  • Analysis of fluid soil-structure interaction problems with the particle finite element method (PFEM) 

    Oñate Ibáñez de Navarra, Eugenio; Celigueta Jordana, Miguel Ángel; Idelsohn Barg, Sergio Rodolfo; Salazar González, Fernando; Larese De Tetto, Antonia; Rossi, Riccardo; Suárez Arroyo, Benjamín; Morán, R. (2012)
    External research report
    Open Access
    We present some developments in the Particle Finite Element Method (PFEM) for analysis of coupled problems in mechanics involving fluid-soil-structure interaction (FSSI). The PFEM uses an updated Lagrangian description to ...
  • A finite calculus formulation of the level set equation 

    Oñate Ibáñez de Navarra, Eugenio; Idelshon, Sergio Rodolfo; Ransau, S. (2003-09)
    External research report
    Open Access
    A finite calculus formulation of the level set equation is presented. Quadratic Galerkin finite elements are used for spatial discretization. A unique stabilization parameter is computed. A time stabilization parameter ...
  • Evolutionary methods for optimal shape design 

    Fung, A.; Pahl, E.; Bugeda Castelltort, Gabriel; Oñate Ibáñez de Navarra, Eugenio (2005-06)
    External research report
    Open Access
    An optimization code called Optima has been developed at the International Centre for Numerical Methods in Engineering (CIMNE). This report validates two reputably robust Evolutionary Algorithms available in Optima and ...
  • Efficient aeroelastic analysis of wind loads on inflatable hangars 

    Flores Le Roux, Roberto Maurice; Ortega, Enrique (International Centre for Numerical Methods in Engineering (CIMNE), 2019)
    Conference report
    Open Access
    Wind loads play a crucial role in inflatable structures. Unfortunately, design loads from safety regulations grossly overestimate the real aerodynamic forces. Thus, a more accurate estimation of wind loads is desirable. ...
  • A finite point method to solve shallow water equations
