    • A distortion measure to validate and generate curved high-order meshes on CAD surfaces with independence of parameterization 

      Gargallo Peiró, Abel; Roca Navarro, Francisco Javier; Peraire Guitart, Jaume; Sarrate Ramos, Josep (John Wiley & Sons, 2016-06)
      Article
      Accés obert
      A framework to validate and generate curved nodal high-order meshes on Computer-Aided Design (CAD) surfaces is presented. The proposed framework is of major interest to generate meshes suitable for thin-shell and 3D finite ...

    • High-order mesh generation on CAD geometries 

      Gargallo Peiró, Abel; Roca Navarro, Francisco Javier; Peraire Guitart, Jaume; Sarrate Ramos, Josep (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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 ...

    • On curving high-order hexahedral meshes 

      Gargallo Peiró, Abel; Ruiz Gironés, Eloi; Roca Navarro, Francisco Javier; 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 ...

    • Optimization of a regularized distortion measure to generate curved high-order unstructured tetrahedral meshes 

      Gargallo Peiró, Abel; Roca Navarro, Francisco Javier; Peraire Guitart, Jaume; Sarrate Ramos, Josep (2015-08-03)
      Article
      Accés obert
      We present a robust method for generating high-order nodal tetrahedral curved meshes. The approach consists of modifying an initial linear mesh by first, introducing high-order nodes, second, displacing the boundary nodes ...

    • Parameter sensitivity analysis of a Constructed Wetlands model for wastewater treatment 

      Blázquez Llistosella, Jordi (Universitat Politècnica de Catalunya, 2013-07-19)
      Tesina
      Accés obert
      Els aiguamolls construïts són sistemes de tractament d’aigües residuals. Es tracta de basses reblertes de graves i plantades amb plantes típiques de zones humides en les quals l’aigua es depura per la interacció entre ...

    • Validation and generation of high-order meshes on parameterized surfaces 

      Gargallo Peiró, Abel; Roca Navarro, Francisco Javier; Peraire Guitart, Jaume; Sarrate Ramos, Josep (Sociedad Española de Métodos Numéricos en Ingeniería (SEMNI), 2013)
