Hi,

Any ideas on the best way to create a velocity profile on my inlet boundary that will vary with time?

The velocity profile should vary as a function of time and radius:

U(r,t)=pi*k*f*(1-(r/rc))*cos(2*pi*f*t)

Thanks

Make Field Function using the equation. Call time step value in the field function. Apply this field function at Inlet Boundary.
