monali2015m is on a distinguished road
Atmospheric boundary layer (ABL)validation case:

I wrote the UDF for all the profiles, and I am stuck at the turbulent intensity
I don't know how to interpolate the following wind tunnel information given by the author any advice?
the author used turbulent kinetic energy based on the mean velocity profile and the measured turbulence intensity as follows:

- The turbulent kinetic energy formula used is k=a*(Uref*I)^2
where a is a constant from 0.5 to 1.5, I turbulent intensity (figure 1)

- the wind tunnel has a reference turbulent intensity of 10% at building height, a turbulent intensity of 17% near the ground (12mm), and 5% at gradient height (728mm).
