Yang Guest Posts: n/a	Hello all I use finite volume method and VOF method to simulate the filling process of a viscous liquid in a mold. As a two-phase flow. I meet some problems in boundary conditions. I apply no-slip boundary conditions at the mold wall filled with liquid, i.e. u=0. I want to apply free-slip boundary conditions at the mold wall filled with gas, but I don't know how I describe the free-slip boundary conditions by means of the formulation. Who can give me some advice? Thanks in advance. Regards Yang
