Dear John,

Yes, your understanding is correct. This is documented a bit in Appendix B of the TurbSim User's Guide.

Dear Jason,

Thanks for getting back to me so quickly and clearing that up for me.

Just one more question;

Am I correct in thinking that for fatigue analysis of different DLCs that have the same wind conditions (e.g. DLC 1.2 and 2.4 - NTM, Vin<Vhub<Vout), the same TurbSim wind files can be used?

It is just FAST that will have to be adjusted to account for the difference between cases (e.g. in this case where DLC 2.4 describes power production loading with a control system fault,electrical fault or loss of electrical network)?

Thanks again,

Kind Regard,

John Boundy
