Combining Size-Preserving and Smoothing Procedures for Adaptive Quadrilateral Mesh Generation
It is well known that the variations of the element size have to be controlled in order to generate a high-quality mesh. Hence, several techniques have been developed to limit the gradient of the element size. However, the obtained discretizations do not always reproduce the prescribed size function. This is of the major importance for quadrilateral meshes, since they are much more constrained ...
متن کاملSize Functions and Mesh Generation for High-Quality Adaptive Remeshing
We present a new method for remeshing of triangular and tetrahedral meshes. Relative element sizes are computed from an error estimation. Then their gradient is limited in an optimal way by solving a Hamilton-Jacobi equation numerically. The new mesh is generated using smoothing-based iterations with connectivity updates (changes in topology of the mesh). The boundary nodes are projected using ...
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.
متن کاملQuadrilateral Mesh Generation using Templates
Abstract. This paper describes a quadrilateral mesh generation algorithm ideally suited for transition subdomain meshes in the context of any domain decomposition meshing strategy. The algorithm is based on an automatic hierarchical region decomposition in which, in the last level, it is possible to generate quadrilateral elements with a conventional mapping strategy. In two dimensions, a subdo...
متن کاملParallel Feature-Preserving Mesh Smoothing
We present a parallel approach for optimizing surface meshes by redistributing vertices on a feature-aware higher-order reconstruction of a triangulated surface. Our method is based on a novel extension of the fundamental quadric, called the medial quadric. This quadric helps solve some basic geometric problems, including detection of ridges and corners, computation of one-sided normals along r...
