文摘
- •
An improved grid-based algorithm for the adaptive generation and regeneration of hexahedral element mesh is presented.
- •
Eight different types of free element facet configurations are given for the mesh matching to the surface of the solid model.
- •
To improve the quality of the surface meshes and the interior elements, an optimization approach is proposed.
- •
Several examples demonstrate the effectiveness and robustness of the algorithm.
