Boundary conditions Poiseuille flow, Y pipe, 3D geometry
 

Hi!!!!
I need an help, maybe it is easy but I'm in trouble with boundary conditions for my 3D geometry of pipes. :confused:
The shape is a Y, I have pressure and velocity in inlet and outles and my flow is laminar so I'm trying to run the simulation with icoFoam but the current number is to high.

Any suggestion for P and V for my simulation???????

thank you!
