| Abstract: | The improved variable seepage matrix method of the compound element was presented for the seepage problem with free surface in the light of usage of continuous penalty function.Then the disadvantage of unstable solution was optimized and the speed and precision were improved.It was validated programming the finite element method by a case.The complex seepage field about steady flow and unsteady flow was simulated by this method efficiently and subtly. |
| Keywords: | free surface seepage finite element improved variable seepage matrix method |
