Unstructured hexahedral non-conformal mesh generation
Mesh generation is a process of spatial subdivision of a generally complex domain into simple-shaped sub-volumes of pre-defined topology. These sub-volumes are usually referred to as mesh elements or cells. Elements of a mesh are connected to each other, they do not intersect with each other and cover the entire domain. The problem of generation of computational meshes arose as a pre-requisite ...
متن کاملSheet-Based Hexahedral Mesh Generation
Historically, hexahedral finite element mesh generation has required significant geometric decomposition with the resulting consequence that generating hexahedral meshes can be extremely difficult to perform and automate and the process often takes several orders of magnitude longer in time to complete than current methods for generating tetrahedral meshes. In this work, we present methods for ...
متن کاملConforming Hexahedral Mesh Generation via Geometric Capture Methods
An algorithm is introduced for converting a non-conforming hexahedral mesh that is topologically equivalent and geometrically similar to a given geometry into a conforming mesh for the geometry. The procedure involves embedding geometric topology information into the given non-conforming base mesh and then converting the mesh to a fundamental hexahedral mesh. The procedure is extensible to mult...
متن کاملAlgorithms for Quadrilateral and Hexahedral Mesh Generation
This lecture reviews the state of the art in quadrilateral and hexahedral mesh generation. Three lines of development – block decomposition, superposition and the dual method – are described. The refinement problem is discussed, and methods for octree-based meshing are presented.
