Unstructured Tetrahedral Mesh Generation Technology
The whole process of mesh generation is presented in detail. Advancing front technique (AFT) is proposed for 3D tetrahedral mesh generation [1]. AFT starts from initial front. Initial front is a boundary surface conformal triangulation. On each step a new tetrahedron is constructed and the front is updated. At this point local mesh size could be selected automatically in order to create quasi-u...
متن کاملRepresenting urban geometries for unstructured mesh generation
We present a robust and automatic method to generate an idealized surface geometry of a city landscape ready to be meshed for computer simulations. The city geometry is idealized for non viscous flow simulations and targets two main geometrical features: the topography and the city blocks. The procedure is fully automatic and demands no human interaction given the following source data: the cit...
متن کاملMesh Generation for Implicit Geometries
We present new techniques for generation of unstructured meshes for geometries specified by implicit functions. An initial mesh is iteratively improved by solving for a force equilibrium in the element edges, and the boundary nodes are projected using the implicit geometry definition. Our algorithm generalizes to any dimension and it typically produces meshes of very high quality. We show a sim...
متن کاملMesh Generation for Symmetrical Geometries
Symmetries are not only fascinating, but they can also be exploited when designing numerical algorithms and data structures for scientific engineering problems in symmetrical domains. Geometrical symmetries are studied, particularly in the context of so called equivariant operators, which are relevant to a wide range of numerical applications. In these cases, it is possible to exploit the symme...
متن کاملFine-Grained Parallel Algorithm for Unstructured Surface Mesh Generation
Surface mesh generation is one time-consuming step in preparing an unstructured mesh model. However, its parallelisation attracts little attention. In this study, a fine-grained parallel surface meshing algorithm is proposed by taking advantage of the parallelism within the meshing process of a single face. Compared with the scheme which meshes the faces individually in parallel, the proposed a...
