| Abstract: | 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. |
