An Automatic Hexahedral Mesh Generation System Based on the Shape-Recognition and Boundary-Fit Methods
نویسنده
چکیده
A general-purpose automatic hexahedral mesh generation system for FEA (Finite Element Analysis) was developed based on a shape recognition technique and the boundary-fit method. In this system, a solid model is analyzed and decomposed into single-connected sub-models. Then, other sub-models topologically identical to the original ones are constructed using only orthogonal angles. Cubes are used to construct intermediate models, which reassemble these, and finally, hexahedral meshes are generated by mapping the cubes back onto the original solid model.

Volume Decomposition and Feature Recognition for Hexahedral Mesh Generation
Considerable progress has been made on automatic hexahedral mesh generation in recent years. Several automatic meshing algorithms have proven to be very reliable on certain classes of geometry. While it is always worth pursuing general algorithms viable on more general geometry, a combination of the well-established algorithms is ready to take on classes of complicated geometry. By partitioning...
متن کاملUnstructured hexahedral non-conformal mesh generation
Mesh generation is a process of spatial subdivision of a generally complex domain into simple-shaped sub-volumes of pre-defined topology. These sub-volumes are usually referred to as mesh elements or cells. Elements of a mesh are connected to each other, they do not intersect with each other and cover the entire domain. The problem of generation of computational meshes arose as a pre-requisite ...
متن کاملAn Automatic 3D Mesh Generation Method for Domains with Multiple Materials.
This paper describes an automatic and efficient approach to construct unstructured tetrahedral and hexahedral meshes for a composite domain made up of heterogeneous materials. The boundaries of these material regions form non-manifold surfaces. In earlier papers, we developed an octree-based isocontouring method to construct unstructured 3D meshes for a single-material (homogeneous) domain with...
متن کاملReceding Front Method: A New Approach Applied to Generate Hexahedral Meshes of Outer Domains
Two of the most successful methods to generate unstructured hexahedral meshes are the grid-based methods and the advancing front methods. On the one hand, the grid-based methods generate high quality elements in the inner part of the domain using an inside-outside approach. On the other hand, advancing front methods generate high quality hexahedra near the boundary using an outside-inside appro...
متن کاملA Density Control Based Adaptive Hexahedral Mesh Generation Algorithm
A density control based adaptive hexahedral mesh generation algorithm for three dimensional models is presented in this paper. The first step of this algorithm is to identify the characteristic boundary of the solid model which needs to be meshed. Secondly, the refinement fields are constructed and modified according to the conformal refinement templates, and used as a metric to generate an ini...
