    The meshless method Smoothed Particle Hydrodynamics (SPH) is one of the primarily developed numerical methods in the meshless methods family. It has been proven to work well with problems of free surface fluid flows. For ...
  • Applications of turbulence modeling in civil engineering 

    Cotela Dalmau, Jordi (Universitat Politècnica de Catalunya, 2016-01-15)
    Doctoral thesis
    Open Access
    This thesis explores the use of stabilized finite element formulations for the incompressible Navier-Stokes equations to simulate turbulent flow problems. Turbulence is a challenging problem due to its complex and dynamic ...
  • Computational multiscale analysis of masonry structures 

    Petracca, Massimo (Universitat Politècnica de Catalunya, 2016-04-13)
    Doctoral thesis
    Open Access
    Covenantee:  Università degli Studi G.D'Annunzio
    Masonry is an ancient building material that has been used throughout the history, and it is still used nowadays. Masonry constitutes the main building technique adopted in historical constructions, and a deep understanding ...

    Millet Biosca, Lluís (Universitat Politècnica de Catalunya, 2016-06)
    Master thesis
    Restricted access - confidentiality agreement
    Covenantee:  Fraunhofer-Institut für Solare Energiesysteme
    In this thesis, the electrochemical and thermal behavior of an LFP lithium-ion pouch battery is modeled, within a finite elements method framework, in order to study the fast charge procedure that is sought in most of ...
  • Evaluación de una herramienta para el estudio de problemas de interacción fluido-estructura 

    Beltrán Coloma, Laura (Universitat Politècnica de Catalunya, 2017-06)
    Bachelor thesis
    Open Access
    A lo largo de los últimos años ha existido un gran desarrollo de distintas técnicas computacionales con el propósito de resolver, de una forma rápida y eficaz, problemas reales de interacción entre distintos materiales. ...
  • FSI procedures for Civil Engineering Applications 

    Zorrilla Martínez, Rubén (Universitat Politècnica de Catalunya, 2016-07-21)
    Master thesis
    Open Access
    Implementation of a FSI procedure involving the interaction of shell structures and fluids.
  • Gradient based porosity calculation in casting simulation 

    Díez Rodríguez, Daniel (Universitat Politècnica de Catalunya, 2017-06-15)
    Master thesis
    Open Access
    Porosity is one of the most common defects in casting production. When some parts of the casting begin to solidify they contract due to the difference of densities between the liquid and solid phases. The areas that are ...
  • Modelado de multifractura discreta en materiales quasi-frágiles 

    Lafontaine, Nelson M. (Universitat Politècnica de Catalunya, 2016-01-18)
    Doctoral thesis
    Open Access
    The stated goal of this work is to develop a numerical explicit finite element method able to effectively address the strain localization process, discrete fracture and fragmentation process in quasi-brittle materials, ...
