I see i can only set the boundary condition (Fully Developed Flow) when i define inlet or outlet velocity
can i set the boundary condition (Fully Developed Flow) with inlet or outlet pressure ?
my boundary conditions in my problem are
1-lower surface (real wall)
2-upper surface (real wall with motion)
3-inlet pressure

4-outlet pressure
i need to solve this problem with (Fully Developed Flow) assumption can i ?
