Optimizing mesh distortion by hierarchical iteration relocation of the nodes on the CAD entities
Ruiz-Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (Elsevier, 2014)
Text en actes de congrés
Accés obertMesh 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 ... -
Preserving isotropic element size functions in adaptivity, quadrilateral and hexahedral mesh generation
Ruiz-Gironés, Eloi; Roca Navarro, Francisco Javier; Sarrate Ramos, Josep (2013)
Article
Accés restringit per política de l'editorialIn electric circuit theory, it is of great interest to compute the effective resistance between any pair of vertices of a network, as well as the Kirchhoff Index. During the last decade these parametres have been applied ... -
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'editorialTwo 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 obertIn 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 obertThe 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 obertTwo 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 obertDiscretization 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 obertThe 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 obertWe 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 ...
