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 کاملParallel unstructured mesh generation by an advancing front method
Mesh generation is a critical step in high fidelity computational simulations. High quality and high density meshes are required to accurately capture the complex physical phenomena. A parallel framework has been developed to generate large-scale meshes in a short period of time. A coarse volume mesh is generated first to provide the basis of block interfaces and partitioned into a number of su...
متن کاملOptimization Strategies in Unstructured Mesh Generation
We propose a new optimization strategy for unstructured meshes that, when coupled with existing automatic generators, produces meshes of high quality for arbitrary domains in 3D. Our optimizer is based upon a non-differentiable definition of the quality of the mesh which is natural for finite element or finite volume users: The quality of the worst element in the mesh. The dimension of the opti...
متن کاملUnstructured Mesh Generation for 3 Dviscous
In this paper we review the procedures which are currently available for the generation of unstructured meshes suitable for use in the simulation of high Reynolds number viscous ows. For such simulations, computational eeciency generally dictates the requirement for the use of highly stretched cells in viscous dominated regions. Meshes of this type cannot be directly generated by the classical ...
