Turbsim with Aero_driver (GF wind array was exhaustrd at 0.08264s )

[robytian]

Dear all
I tried to simulate two 5MW rotors in the Aerodriver program, and the wheel hub height was placed at 200m. I wanted to simulate the wind area where XY was 600400. My inp was set as follows, the azimuthing Angle was 6°, and RPM12.1, so the time step was 0.08264. But the calculation times incorrectly remind me that I need to double the time step, why?

I've tried adjusting the time step in .inp to the recommended 0.0324439, and a smaller 0.02, and still get the error.

Dear @robytian,

I'm not exactly sure why you are receiving this error, but I would suggest changing UsableTime in TurbSim to "ALL" and regenerating the wind data file, which will make the TurbSim output periodic in the X / time direction, which should avoid the standalone AeroDyn driver from generating any errors about the wind array not being large enough in the X / time direction.

Best regards,
