| Abstract: | A method for the resolution of Darcy velocity under the condition of the first boundary is presented. The finite element equation is applied to get the hydraulic gradient and seepage velocity of nodes in the first boundary. The method is verified by the simulation of an ideal test case. A good agreement is found between the analytical solution and the numerical solution. Example calculation shows the efficiency of the method. |
