(1) traction jump due to the surface tension. (2) if it is a steady one, free surface is a stream line, that is, normal direction velocity vanishes.

Thanks I am tryng to solve a flow for a laminar 2D incompressible, and viscous flow, but on the FS I can set that the pressure is the atmospheric, but what happen with the velocity.
