Conformal Hexaedral Meshes and Adaptive Mesh Refinement
نویسندگان
چکیده
During a numeric simulation based on the finite element method, the h-refinement of the mesh consists in splitting the elements where an error indicator is higher than a threshold. One major point is that the final mesh must be conformal. When the mesh is defined only by triangles or tetrahedra, the junction between two zones with a different level of refinement has been solved for many years. When the mesh is made of hexahedra, this junction cannot be made of hexahedra. A proposal is made in this paper to connect the zones with some specific elements. Two applications are presented here and show the efficiency of the method.

Conformal Refinement of Unstructured Quadrilateral Meshes
A multilevel adaptive refinement technique is presented for unstructured quadrilateral meshes in which the mesh is kept conformal at all times. This means that the refined mesh, like the original, is formed of only quadrilateral elements that intersect strictly along edges or at vertices, i.e., vertices of one quadrilateral element do not lie in an edge of another quadrilateral. Elements are re...
متن کاملAdaptive Mesh Refinement Techniques for High-order Finite-volume Weno Schemes
This paper demonstrates the capabilities of Adaptive Mesh Refinement Techniques (AMR) on 2D hybrid unstructured meshes, for high order finite volume WENO methods. The AMR technique developed is a conformal adapting unstructured hybrid quadrilaterals and triangles (quads & tris) technique for resolving sharp flow features in accurate manner for steady-state and time dependent flow problems. In t...
متن کاملAdaptive mesh refinement approach to construction of initial data for black hole collisions
The initial data for black hole collisions is constructed using a conformal-imaging approach and a new adaptive mesh refinement technique, a fully threaded tree (FTT). We developed a secondorder accurate approach to the solution of the constraint equations on a non-uniformly refined high resolution Cartesian mesh including second-order accurate treatment of boundary conditions at the black hole...
متن کاملConformal Refinement of All-Quadrilateral and All-Hexahedral Meshes According to an Anisotropic Metric
Conformal refinement using a shrink and connect strategy known as pillowing or buffer insertion contracts contiguous elements of an all-quadrilateral or an all-hexahedral mesh and reconnects them to locally increase vertex density. Using layers as shrink sets, the present method anisotropically refines an initial mesh to match a prescribed size map expressed as a metric field. An anisotropic sm...
متن کاملOctasection-based Refinement of Finite Element Approximations on Tetrahedral Meshes that Guarantees Shape Quality
Adaptive refinement of finite element approximations on tetrahedral meshes is generally considered to be a non-trivial task. (We wish to stress that this paper deals with mesh refinement as opposed to remeshing.) The splitting individual finite elements needs to be done with much care to prevent significant deterioration of the shape quality of the elements of the refined meshes. Considerable c...
