  • Cell-centred model for the simulation of curved cellular monolayers 

    Mosafa, Payman; Asadipour, Nina; Millán, Raúl Daniel; Rodríguez Ferran, Antonio; Muñoz Romero, José (2015)
    Article
    Open Access
    This paper presents a cell-centred model for the simulation of planar and curved multicellular soft tissues. We propose a computational model that includes stress relaxation due to cell reorganisation (intercellular ...
  • Size-preserving size functions and smoothing procedures for adaptive quadrilateral mesh generation 

    Ruiz-Gironés, Eloi; Roca Navarro, Xevi; Sarrate Ramos, Josep (2015-07-01)
    Article
    Restricted access - publisher's policy
    The generation of meshes that correctly reproduce a prescribed size function is crucial for quadrilateral meshing due to two reasons. First, quadrilateral meshes are difficult to adapt to a given size field by refining or ...
  • Mapping forces and kinematics during collective cell migration 

    Serra-Picamal, Xavier; Conte, Vito; Sunyer, Raimon; Muñoz Romero, José; Trepat, Xavier (2015-01-08)
    Article
    Restricted access - publisher's policy
    Fundamental biological processes including morphogenesis and tissue repair require cells to migrate collectively. In these processes, epithelial or endothelial cells move in a cooperative manner coupled by intercellular ...
  • High-order mesh curving by distortion minimization with boundary nodes free to slide on a 3D CAD representation 

    Ruiz-Gironés, Eloi; Roca Navarro, Xevi; Sarrate Ramos, Josep (2016-03)
    Article
    Restricted access - publisher's policy
    We propose a 3D mesh curving method that converts a straight-sided mesh to an optimal-quality curved high-order mesh that interpolates a CAD boundary representation. The main application of this method is the generation ...
  • The receding front method applied to hexahedral mesh generation of exterior domains 

    Ruiz-Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (2011-11-30)
    Article
    Open Access
    Two of the most successful methods to generate unstructured hexahedral meshes are the grid-based methods and the advancing front methods. On the one hand, the grid-based methods generate high-quality hexahedra in the inner ...
  • Cell-based maximum entropy approximants 

    Millán, Raúl Daniel; Sukumar, N; Arroyo Balaguer, Marino (2015-02-01)
    Article
    Restricted access - publisher's policy
    In this paper, we devise cell-based maximum-entropy (max-ent) basis functions that are used in a Galerkin method for the solution of partial differential equations. The motivation behind this work is the construction of ...
  • An efficient and general approach for implementing thermodynamic phase equilibria information in geophysical and geodynamic studies 

    Afonso, Juan Carlos; Zlotnik, Sergio; Díez, Pedro (2015-10-25)
    Article
    Restricted access - publisher's policy
    We present a flexible, general, and efficient approach for implementing thermodynamic phase equilibria information (in the form of sets of physical parameters) into geophysical and geodynamic studies. The approach is based ...
  • eXtended Hybridizable Discontinous Galerkin (X-HDG) for void problems 

    Gurkan, Ceren; Sala Lardies, Esther; Kronbichler, Martin; Fernandez Mendez, Sonia (2015-07-06)
    Article
    Restricted access - publisher's policy
    A strategy for the Hybridizable Discontinous Galerkin (HDG) solution of problems with voids, inclusions or free surfaces is proposed. It is based on an eXtended Finite Element (X-FEM) philosophy with a level-set description ...
  • Least-squares approximation of affine mappings for sweep mesh generation. Functional analysis and applications 

    Roca Navarro, Xevi; Sarrate Ramos, Josep (2013-01)
    Article
    Open Access
    Sweep methods are one of the most robust techniques to generate hexahedral meshes in extrusion volumes. The main issue in sweep algorithms is the projection of cap surface meshes along the sweep path. The most competitive ...
  • Esquema adaptativo para problemas tridimensionales de convección-difusión 

    Monforte, Lluis; Pérez Foguet, Agustí (2014)
    Article
    Open Access
    We present an adaptive scheme for three-dimensional convection-diffusion problems discretized by the Finite Element Method. The adaptive scheme is based on a remeshing strategy that applies a maximum volume constraint to ...
