Hi there ! I'm conducting the assessment of a complex site on WAsP-CFD and I have a question about the validity of a method. When I assess a site on standard WAsP I use to calculate the wind profile at the met mast with the power law which I think more trustful. As I got different results for the vertical extrapolation I balance the height of the mast on WAsP to get the same wind speed at the hub height at the reference mast. For example if I want to compute the wind speed at 80m with a 60m met mast I calculate the wind speed at the mast at 80m with the power law and I obtain 7.5 m/s. WAsP gives me at the same point from the same mast 7.8 m/s. Therefore I reduce the height mast at 78m on WAsP to reach 7.5 m/s. Then I've got the same starting point and I can compute the wind speed of turbines at 80m (78m in WAsP). I hope my explanation is clear. As WAsP-CFD is based on a different model which takes into account NS equations, I would like to know if it is possible to follow the same method on this tool or if it will distort the results ? Thanks for you answer
