value for pressureInletOutlet bc
 
I want to use pressureinletoutletVelocity boundary condition for velocity at outlet as this is not fully developed (there is a chance to be backflow) flow. But my question is what the value I should set? Is it always (0 0 0)? What is the function of this fixed value of velocity?

type pressureInletOutletVelocity;
value uniform (0 0 0)

as i guess this BC calculate velocity based on pressure, so
value uniform (0 0 0)
is place holder

Thanx Nima Sam for your reply.

If I put (0 0.6 0) instead of (0 0 0) whether it will affect the simulation or not?

i guess nope :), but i recommend you to see source code
