چکیده

This work presents an adaptive mesh generation strategy for parametric surfaces. The proposed strategy is controlled by curvatures and the error measured between the analytical and discrete curvatures guides the adaptive process. The analytical curvature is a mathematical representation that models the domain, whereas the discrete curvature is an approximation of that curvature and depends directly on the used mesh. The proposed strategy presents the following aspects: it is able to refine and coarsen regions of the mesh; it considers the local error measures to ensure good global quality; it ensures good transition of the mesh and it deals with any type of parametric surfaces since it works in the parametric space.

Curvature Based Mesh Improvement

It is very important to improve the quality of surface meshes for numerical simulations, solid mesh generation, and computer graphics applications. Optimizing the form of the mesh elements it is necessary to preserve new nodes of the mesh as close as possible to a surface approximated by the initial mesh. This paper proposes a novel technique in which both of the requirements to mesh improvemen...

A modeling methodology for finite element mesh generation of multi-region models with parametric surfaces

This paper presents a description of the reorganization of a geometric modeler, MG, designed to support new capabilities of a topological module (CGC) that allows the detection of closed-off solid regions described by surface patches in non-manifold geometric models defined by NURBS. These patches are interactively created by the user by means of the modeler’s graphics interface, and may result...

Unstructured Triangular - Quadrilateral Mesh Generation . Application to Surface Meshing

To start, we recall a mesh generation method, allowing to create a so called unit mesh, which is an extension of the classical Delaunay method in the case where the process is governed via an isotropic or an anisotropic control space. Then we introduce a conversion method from a triangular mesh to a quadrilateral mesh. Furthermore, we describe the generalization of this method to adaptive surfa...
