    • Receding front method: a new approach applied to generate hexahedral meshes of outer domains 

      Roca Navarro, Francisco Javier; Ruiz-Gironés, Eloi; Sarrate Ramos, Josep (2010)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      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 elements in the inner ...

    • Simultaneous untangling and smoothing of quadrilateral and hexahedral meshes using an object-oriented framework 

      Ruiz-Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep; Montenegro Armas, Rafael; Escobar Sánchez, José M. (2015-02-01)
      Article
      Accés obert
      In this work, we present a simultaneous untangling and smoothing technique for quadrilateral and hexahedral meshes. The algorithm iteratively improves a quadrilateral or hexahedral mesh by minimizing an objective function ...

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

      Ruiz-Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (2015-07-01)
      Article
      Accés obert
      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 ...

    • 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
      Accés obert
      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 ...

    • Unstructured and semi-structured hexahedral mesh generation methods 

      Sarrate Ramos, Josep; Ruiz-Gironés, Eloi; Roca Navarro, Francisco Javier (Saxe-Coburg, 2014)
      Article
      Accés obert
      Discretization techniques such as the finite element method, the finite volume method or the discontinuous Galerkin method are the most used simulation techniques in ap- plied sciences and technology. These methods rely ...

    • Using a computational domain and a three-stage node location procedure for multi-sweeping algorithms 

      Ruiz-Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (2011)
      Article
      Accés obert
      The multi-sweeping method is one of the most used algorithms to generate hexahedral meshes for extrusion volumes. In this method the geometry is decomposed in sub-volumes by means of projecting nodes along the sweep direction ...

    • Visualization of pentatopic meshes 

      Belda Ferrín, Guillem; Ruiz-Gironés, Eloi; Roca, Xevi (Barcelona Supercomputing Center, 2020-05)
      Text en actes de congrés
      Accés obert
      We propose a simple tool to visualize 4D unstructured pentatopic meshes. The method slices unstructured 4D pentatopic meshes (fields) with an arbitrary 3D hyperplane and obtains a conformal 3D unstructured tetrahedral ...
