FAST Simulation with fixed turbulence intensity

Postby Piero.Mazza » Mon Jul 08, 2019 7:27 am

To whom it may concern,

I would need to run a FAST simulation imposing a fixed value of turbulence intensity for different wind speeds (meaning that i don't want to follow the scaling rules prescribed by the IEC 61400 standards). Can anybody please tell me if it is possible and how to do it?
Thank you in advance.

with Kind Regards,

Dear Piero,

Yes, this is certainly possible. Instead of following the turbulence scaling according to IEC 61400, you can specify the turbulence intensity directly in TurbSim via input parameter IECturbc.
