kamyar New Member Join Date: Jan 2013 Posts: 17 Rep Power: 13	Hi I'm solving the navier stokes equation for flow inside a wavy channel using element based finite volume method on a co-located grid. I want to implement periodic boundary condition on inlet and outlet. I specified the velocities at the inlet and set the velocities at outlet equal to inlet but i don't know what to do with pressure. It would be great if someone could help me. thanks
