| Abstract: | The h-version adaptive finite element method for 3-D seepage problem is presented in this paper. The adaptive system includes 4 modules: 3-D mesh generation, finite element analysis for 3-D seepage, mesh error estimation and post-process. The effectiveness of this system is verified by the given example. |
