Compiling FAST v8.12 on Mac

Hello Surya,

I saw you have a problem of violating the small angle assumption.
You can read this poster to check your simulation case.

NREL 5MW controls (DLL interface)

Hi: I am a new FAST user, and I tested the 1.5MW turbsine. I used PitchCntrl() and Pitch.ipt to do the pitch control, everything is good. Then I download the 5MW files, and I also want to do the controls on this kind of turbine, but I found that there donot have control files that can be directly used by FAST. In 5MW turbine, you use the DLL to do the controls, but I never use DLL before, could you give me some advices? Thanks.

Thanks
Xiao
