  • Modeling flexoelectricity in soft dielectrics at finite deformation 

    Codony Gisbert, David; Gupta, Prakhar; Marco Alacid, Onofre; Arias Vicente, Irene (2021-01)
    Article
    Restricted access - publisher's policy
    This paper develops the equilibrium equations describing the flexoelectric effect in soft dielectrics under large deformations. Previous works have developed related theories using a flexoelectric coupling tensor of mixed ...

  • Hybridisable discontinuous Galerkin formulation of compressible flows 

    Vila Pérez, Jordi; Giacomini, Matteo; Sevilla Cárdenas, Rubén; Huerta, Antonio (2021)
    Article
    Restricted access - publisher's policy
    This work presents a review of high-order hybridisable discontinuous Galerkin (HDG) methods in the context of compressible flows. Moreover, an original unified framework for the derivation of Riemann solvers in hybridised ...

  • An OpenFOAM set-up for simulating thermal winds in mountain/valley configurations 

    Athota, Rathan Babu; Rojas Gregorio, José Ignacio; Arias Calderón, Santiago; Villardi de Montlaur, Adeline de (2021)
    Conference report
    Open Access

  • Measuring and improving the geometric accuracy of piece-wise polynomial boundary meshes 

    Ruiz Gironès, Eloi; Sarrate Ramos, Josep; Roca Navarro, Francisco Javier (2021-10-15)
    Article
    Open Access
    We present a new disparity functional to measure and improve the geometric accuracy of a curved high-order mesh that approximates a target geometry model. We have devised the disparity to account for compound models, be ...

  • An Introduction to the hybridizable discontinuous Galerkin method 

    Fernández Méndez, Sonia (Springer, 2021-01-05)
    Part of book or chapter of book
    Open Access
    This chapter in intended to be a didactical introduction to the Hybridizable Discontinuous Galerkin (HDG) method, including the formulation and its implementation. The Laplace and Stokes equations are considered as ...

  • Subdivided linear and curved meshes preserving features of a linear mesh model 

    Jiménez Ramos, Albert; Gargallo Peiró, Abel; Roca Navarro, Francisco Javier (Sandia National Laboratories, 2019)
    Conference report
    Open Access
    To provide straight-edged and curved piece-wise polynomial meshes that target a unique smooth geometry while preserving the sharp features and smooth regions of the model, we propose a new fast curving method based on ...

  • A Cº interior penalty method for 4th order PDEs 

    Fojo, Dani; Codony Gisbert, David; Fernández Méndez, Sonia (2020-12-01)
    Article
    Open Access
    A method to solve 4th-order PDEs using the Finite Element Method (FEM) with standard C0 elements is derived and studied. It is based on a special weak form accounting for the discontinuous derivatives of the approximation ...

  • A new 3D hybrid model for epithelial morphogenesis 

    Muñoz Romero, José (2021-03-22)
    Article
    Open Access
    Wound healing is a biological mechanism that allows the integrity and functionality of tissues to be preserved. Dr Jose Muñoz, Associate Professor at the Laboratory of Numerical Analysis (LaCàN), Universitat Politècnica ...

  • Effects of time delays and viscoelastic parameters in oscillatory response cell monolayers 

    Borja, Cristian; Moral, Elena; Muñoz Romero, José (Elsevier, 2021-01-15)
    Part of book or chapter of book
    Open Access
    Oscillatory response of cellular tissues has been observed in multipleembryogenetic developmental stages. The source of these oscillations hasbeen attributed to imbalance of instabilities in the chemo-mechanical sig-nalling ...

  • OpenFOAM computational fluid dynamics simulations of thermal wind generation in mountain/valley configurations 

    Athota, Rathan Babu; Villardi de Montlaur, Adeline de; Arias Calderón, Santiago; Rojas Gregorio, José Ignacio (2021)
    Conference report
    Open Access
    Thermal winds appear in mountainous areas and valleys due to temperature gradients caused by the buoyancy effects associated with the diurnal heating-cooling cycle of the lower atmosphere. These winds develop over complex ...

  • Error estimation for proper generalized decomposition solutions: a dual approach 

    Reis, Jonatha; Almeida, José Paulo Moitinho de; Díez, Pedro; Zlotnik, Sergio (2020-12-15)
    Article
    Restricted access - publisher's policy
    The Proper Generalized Decomposition is a well established reduced order method, used to efficiently obtain approximate solutions of multi-dimensional problems in a procedure that controls the effects of the "curse of ...
