I am modelling an open channel with periodic boundary conditions at inlet/outlet and symmetry boundary condition at free surface. How can I specify pressure gradient in periodic boundary condition panel for this open channel

If you specify something as a periodic boundary, you can't specify it as a pressure boundary as well. Periodic boundary means that what leaves the other side comes in that side.
