Free-Lagrange method has been combined with the free-mesh FEM and applied to the numerical simulation of viscous free surface flows. The nodes distributed over the fluid region are regarded as fluid particles and moved in a Lagrangian manner every time step. In this paper, we report a new numerical technique for calculating the interaction between the fluid and rigid walls. The proposed method has been applied to the broken-dam problem in a bounded region in which flowing liquid strikes a rigid vertical wall and run up along it. Encouraging numerical results have been obtained.
