Setting outlet Pressure boundary condition using CAFFA code
 
I am using CAFFA code for solving a flow field for an impeller . i have a problem that is the at inlet to the code we have velocity boundary conditions and outlet we have outlet flow boundary conditions but for my case i want to have a pressure boundary condition.

I have tried to force the pressure boundary condition by giving P and PP variable values zero along the boundary . but i think i am thinking wrong i want to have a relative pressure zero boundary condition . i tried thinking and changing things in many ways but without sucess. I think i am getting the theory of baoundary conditions for finite volume method wrong.I would like your help in this if possible to know what i must change for getting the pressure boundary outlet condition.



Thank you.
