Difference between IEC wind and Turbsim

[Riad.Elhamoud]

Hello everyone,

Does anyone know the difference between IEC wind and turbsim ?
I know that iec generates velocity field while turbsim generates turbulence correct ?

Thank u

Dear @Riad.Elhamoud,

Similar questions have been asked and answered previously on the forum, e.g.:

IECWind

Dear Satish, TurbSim can be used to generate full-field turbulent wind data files, but it cannot be used to generate deterministic wind events (gusts, etc.) from the IEC standards. For these, IECWind should be used. Regarding the error “this app can’t run on your PC”, a similar issue was reported and solved in the following forum topic by recompiling the provided IECWind source code: IECWind - #18 by MoeMoe.Aye. Best regards,

IECWind / wind-file 1000sec or longer?

Dear Harald, IECWind is simple code for making IEC-style discrete wind data files in AeroDyn’s “hub-height” format (e.g., ECD, EOG, etc.). The TurbSim code has been developed for computing turbulent wind data for AeroDyn based on turbulence spectra, spatial coherence, and component-to-component correlation. You can find the TurbSim code here: wind.nrel.gov/designcodes/preprocessors/turbsim/. Best regards,
