  • Combining size-preserving and smoothing procedures for adaptive quadrilateral mesh generation 

    Ruiz Gironés, Eloi; Roca Navarro, Xevi; Sarrate Ramos, Josep (Springer, 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    It is well known that the variations of the element size have to be controlled in order to generate a high-quality mesh. Hence, several techniques have been developed to limit the gradient of the element size. However, the ...
  • Inserting curved boundary layers for viscous flow simulation with high-order tetrahedra 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Sarrate Ramos, Josep; Peraire Guitart, Jaume (Springer, 2013)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    We propose an a posteriori approach for generating curved meshes for viscous flow simulations composed by high-order tetrahedra. The proposed approach is performed in the following three steps: (1) generate a linear ...
  • Defining quality measures for validation and generation of high-order meshes 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Peraire Guitart, Jaume; Sarrate Ramos, Josep (Springer, 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    A procedure to quantify the distortion (quality) of a high-order mesh composed by curved tetrahedral elements is presented. The proposed technique has two main applications. First, it can be used to check the validity and ...
  • Generation of curved high-order meshes with optimal quality and geometric accuracy 

    Ruiz Gironés, Eloi; Sarrate Ramos, Josep; Roca Navarro, Xevi (Elsevier, 2016)
    Text en actes de congrés
    Accés obert
    We present a novel methodology to generate curved high-order meshes featuring optimal mesh quality and geometric accuracy. The proposed technique combines a distortion measure and a geometric L2-disparity measure into a ...
  • Coupled mantle dripping and lateral dragging controlling the lithosphere structure of the NW-Moroccan margin and the Atlas Mountains: A numerical experiment 

    Zlotnik, Sergio; Jiménez-Munt, Ivone; Fernández Gómez, Manel (2014-02-15)
    Article
    Accés obert
    Recent studies integrating gravity, geoid, surface heat flow, elevation and seismic data indicate a prominent lithospheric mantle thickening beneath the NW-Moroccan margin (LAB >200 km-depth) followed by thinning beneath ...
  • Validation and generation of high-order meshes on parameterized surfaces 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Peraire Guitart, Jaume; Sarrate Ramos, Josep (Sociedad Española de Métodos Numéricos en Ingeniería (SEMNI), 2013)
    Text en actes de congrés
    Accés obert
    We present a technique to extend Jacobian-based distortion (quality) measures for planar triangles to high-order isoparametric elements of any interpolation degree on CAD parameterized surfaces. The resulting distortion ...
  • Flight and passenger delay assignment optimization strategies 

    Villardi de Montlaur, Adeline de; Delgado Muñoz, Luis (2017-08-01)
    Article
    Accés restringit per política de l'editorial
    This paper compares different optimization strategies for the minimization of flight and passenger delays at two levels: pre-tactical, with on-ground delay at origin, and tactical, with airborne delay close to the destination ...
  • Size preserving mesh generation in adaptivity processes 

    Ruiz Gironés, Eloi; Roca Navarro, Xevi; Sarrate Ramos, Josep (Sociedad Española de Métodos Numéricos en Ingeniería (SEMNI), 2013)
    Text en actes de congrés
    Accés obert
    It is well known that the variations of the element size have to be controlled in order to generate a high-quality mesh. Hence, several techniques have been developed to limit the gradient of the element size. Although ...
  • On curving high-order hexahedral meshes 

    Gargallo Peiró, Abel; Ruiz Gironés, Eloi; Roca Navarro, Xevi; Sarrate Ramos, Josep (Elsevier, 2015)
    Comunicació de congrés
    Accés obert
    We present a new definition of distortion and quality measures for high-order hexahedral (quadrilateral) elements. This definition leads to two direct applications. First, it can be used to check the validity and quality ...
