An unstructured quadrilateral mesh generation algorithm for aircraft structures
Because commercial aircraft are built with thin-walled structures, their structural performance is well-modeled using shell-element meshes. However, creating these meshes for the full aircraft configuration can be challenging and presents a bottleneck in the design process, especially in a configuration-level design space. This paper presents an algorithm that automatically creates unstructured...
متن کاملUnstructured 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...
متن کاملEfficient and Accurate Unstructured Mesh Generation
The goal of this project is to create a quality unstructured mesh generation tool. To this end, we have developed a C++ code that combines unconstrained Delaunay triangulation with spring dynamics in order to achieve a high-quality mesh. Our code will be made publicly available as part of the RedPack software package. As a test of this code, we consider in this paper the problem of generating a...
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...
