Profile for U,V,W velocity
 

Hi all

as I know if i want to define velocity profile for X, Y, Z component, I must define three DEFINE_PROFILE(x_velocity, t, i).

as we know i is an integer that is a numerical label for the variable.
Does any one know a method to determine i for X, Y, Z velocity component.

thanks

You can define 3 profiles with DEFINE_PROFILE(x_velocity, thread, position).

While declaring boundary conditions you can set individual profiles for each components.
