    • Checking and improving the geometric accuracy of non-interpolating curved high-order meshes 

      Ruiz Gironés, Eloi; Sarrate Ramos, Josep; Roca Navarro, Francisco Javier (Elsevier, 2015)
      Comunicació de congrés
      Accés obert

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

      Ruiz Gironés, Eloi; Roca Navarro, Francisco Javier; 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 ...

    • Conformal marked bisection for local refinement of n-dimensional unstructured simplicial meshes 

      Belda Ferrín, Guillem; Ruiz Gironés, Eloi; Gargallo Peiró, Abel; Roca, Xevi (Elsevier, 2022)
      Article
      Accés restringit per política de l'editorial
      We present an n-dimensional marked bisection method for unstructured conformal meshes. We devise the method for local refinement in adaptive n-dimensional applications. To this end, we propose a mesh marking pre-process ...

    • Defining an2-disparity measure to check and improve the geometric accuracy of noninterpolating curved high-order meshes 

      Ruiz Gironés, Eloi; Sarrate Ramos, Josep; Roca Navarro, Francisco Javier (Elsevier, 2015)
      Text en actes de congrés
      Accés obert
      We define an2-disparity measure between curved high-order meshes and parameterized manifolds in terms of an2norm. The main application of the proposed definition is to measure and improve the distance between a curved high-order ...

    • Generation of curved high-order meshes with optimal quality and geometric accuracy 

      Ruiz Gironés, Eloi; Sarrate Ramos, Josep; Roca Navarro, Francisco Javier (2016)
      Article
      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 ...

    • 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 ...

    • Optimizing mesh distortion by hierarchical iteration relocation of the nodes on the CAD entities 

      Ruiz Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (2014-08)
      Article
      Accés obert
      Mesh untangling and smoothing is an important part of the meshing process to obtain high-quality discretizations. The usual approach consists on moving the position of the interior nodes while considering fixed the position ...

    • Size preserving mesh generation in adaptivity processes 

      Ruiz Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (Sociedad Española de Métodos Numéricos en Ingeniería (SEMNI), 2013)
