三维复杂域非结构化六面体网格全自动生成方法

Automatic Generation of Unstructured Hexahedron Mesh for 3D Complicated Domain

使用自适应有限单元法在三维复杂域内求解水工及岩土工程问题，讨论了应用行波法在多介质三维复杂块体内六面体单元网格的自动生成过程。其特点是对不规则区域具有较强的适应性，并考虑了节理单元的自动生成。

In this paper, an automatic hexahedron mesh generation method based on the advancing front method is described for the multi-medium 3D complicated domain.The method is applicable to very complicated domains which contain discontinuities and irregular ground surface.It can be used in the adaptive finite element analysis of hydraulic and geotechnical structures.A program is developed according to the method proposedand two examples are given to show its robustness.
