| Abstract: | The free boundary of the seepage flow is a problem of close consideration inengineering. So far. an estimation of the wet set region usually needs a priori beforethe numerical analysis. and the configuration of the free boundary is then obtained bySuccessive approximation, The authors of this paper benefit from a new mathematicalexpression-The variational Inequality-to formulate the free boundary problem,which is then solved by the finite element method Instead of the conventional way of discretization, here finite element mesh is generated in the entere domain of thestudied medin and the free boundary of the seepage region can be defined directlywithout any process of iteration. The investigation gives a new effective scheme for the seepage flow analysis. |
