Parabolic Velocity profile in a channel

mohsen cheraghi · March 6, 2011, 09:17

Hello to all
I'm trying to apply a parabolic velocity profile at inlet of a 2D rectangular channel.
possibly, one way is to apply a nonuniform velocity by specifying velocity of every point of inlet, but it's so hard to change it.
Is any way to adjust a velocity profile by giving a function like Ux = 3(1 - y^2) ?

I tryed to add this class to my project but it did not work. I use openFoam1.7. can any one help me to apply a new B.C like this to my work?
