3d velocity profile
Did anybody know adding 3d UDF velocity profile of Ux= 0.06*pow(10*y,0.13), Uy=Uz=0 to Fluent6.1? It is the boundary layer profile (power law). For 2d I am OK. But for 3D, things seem very complicated for me. I could not figure it out. Could somebody help me out? Thanks in advanced.

Re: 3d velocity profile
It's just the same as in 2D. You just need to know that in the cell centroid vector, x is in position 0, y is in position 1 and z is in position 2.
The function should be the following. Hook it in FLUENT BC panel to your inlet, in the x-velocity box.
DEFINE_PROFILE(my_Ux, t, i)
F_PROFILE(c,t,i) = 0.06*pow(10*y,0.13);
