I too keep the free surface as wall with specified zero stress when modeling fluid flow in tundish. If you do not consider heat transfer then you can change the free surface to be symmetry or pressure inlet condtion. Pressure inlet is what FLuent recommends but I am not sure how because pressure inlet will then ask for velocity and turbulence parameters.
