Hello,
I am trying to run a turbulent downwind simulation with the tower shadow effect turned on but I am getting the error “FF wind array boundaries violated”.
I followed the comments in [url]AeroDyn v15 convergence issues - #13 by Jason.Jonkman] which says[i] “Looking at the AWT27/Test04_AD15.ipt file, I see that the downwind tower shadow model is enabled (TwrShadow = True), with tower analysis nodes starting at ground level (TwrElev = 0). To run this model, you must use wind with data starting at the ground level.”
[/i] However, I am unable to generate wind files from 0m upwards using Turbsim. When I try to do this with a hub height of 200m and grid height & width of 400m, I get an error stating “The lowest grid point (0 m) must be above the ground. Adjust the appropriate values in the input file.” If I use a hub height of 200m and grid height & width of 390m, it generates wind files of heights 5m to 395m.
How do you recommend I go about solving this issue?
Thanks,
Tinu
