Hexahedral Meshing With Varying Element Sizes
Hexahedral (or Hex-) meshes are preferred in a number of scientific and engineering simulations and analyses due to their desired numerical properties. Recent state-of-the-art techniques can generate high quality hex-meshes. However, they typically produce hex-meshes with uniform element sizes and thus may fail to preserve small scale features on the boundary surface. In this work, we present a...
متن کاملAll-hexahedral meshing and remeshing for multi-object manufacturing applications
All‐hexahedral meshing and remeshing algorithms giving support to finite element modeling of manufacturing processes require continuous development for improving its overall robustness and applicability. This paper draws from a previous all‐hexahedral algorithm presented by the authors and proposes new developments related to the construction of adaptive core meshes and processing of multi‐ obj...
متن کاملMethods and Applications of Generalized Sheet Insertion for Hexahedral Meshing
This paper presents methods and applications of sheet insertion in a hexahedral mesh. A hexahedral sheet is dual to a layer of hexahedra in a hexahedral mesh. Because of symmetries within a hexahedral element, every hexahedral mesh can be viewed as a collection of these sheets. It is possible to insert new sheets into an existing mesh, and these new sheets can be used to define new mesh boundar...
متن کاملFull-hexahedral structured meshing for image-based computational vascular modeling.
Image-based computational modeling offers a virtual access to spatially and temporally high resolution flow and structural mechanical data in vivo. Due to inter-subject morphological variability, mesh generation represents a critical step in modeling the patient-specific geometry and is usually performed using unstructured tetrahedral meshing algorithms. Although hexahedral structured meshes ar...
متن کاملSculpting: An Improved Inside-Out Scheme for All-Hexahedral Meshing
Inside-out algorithms provide the ability to generate all hexahedral meshes by first introducing a structured mesh that bounds the complete body modeled, then secondly by manipulating the exterior of this structured mesh to fit the specific boundary of the body. Such algorithms generally provide high quality meshes on the interior of the body but suffer with lower quality elements on the bounda...
