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? |
