Turbsim cyclic frequency f

Good Morning everybody,

by taking a look of the basic theory on Power Spectra, I have noticed that the power spectrum matrix is a multidimensional one: I mean, you have a different NxN matrix for each sampling frequency.
So I would like to know what is the cyclic frequency usually used within the Turbsim code, since I guess it´s not that easy to handle tridimensional matrices.

I really hope somebody could help me in such a way.
Best regards,

Francesco

Hi Francesco,

The frequencies used in TurbSim are determined by the TimeStep and AnalysisTime inputs. You can read about them and how they affect the frequencies in the TurbSim User’s Guide (http://wind.nrel.gov/designcodes/preprocessors/turbsim/TurbSim.pdf).
