Hello Everyone,


I have a very basic question regarding the boundary condition "PressureInletOutletVelocity",



From the user guide of Openfoam, it seems that it is applied at the Outlet. Is it right?


Is this a boundary condition for Pressure? or Velocity?


Thank you

hi Reza...yes it is applied at outlet for velocity ( i guess that when we use total pressure bouandary condition for pressure we can use PressureInletOutletVelocity for velocity ,but im not sure)

Thank you so much for your reply.


"pressureInletOutletVelocity" we apply this boundary condition at outlet for velocity only if we have backflow?


because in my problem, I don't have any backflow.

you can see this tutorial:incompressible.pimpleFoam,Tjunction....i guess that this bouandary condition can used for velocity (and not just for outlet)when we use total pressure in pressure file
you can use this command in trminal for found more tutorial
grep -r "pressureInletOutletVelocity" *

i hope this can help you.
