Hi Friends,

I'm working on a simple natural ventilation case for a urban site. The ground surface is one patch I have, how calculate average wind velocity 1.5m above ground? Through isosurface or 'fieldaverage' function?

Btw, I tried fieldaverage function, but cannot get the difference between 'Umean' and 'UPrime2Mean', can anyone help tell?

Thanks a lot.
