Re: API wind spectrum

Hi Dr. Jason, I've tried to set the URef = 16.04 m/s and "PL" for WindProfileType, unfortunately, the TurbSim abort by giving the same previous warning CalcFourierCoeffs:CalcFourierCoeffs_API:Error in Cholesky factorization . I managed to run another code by changing the Turbulence model t...

Re: API wind spectrum

Dear Dr. Jason, Noted on the IECturb value and WindProfileType. However, since the API Turbulence model is selected, the RefHt cannot be set to 90 metres because the same warning regarding the RefHt=10 m is required. I try to put any values (80m, 50m and 4m), but still it required to be RefHt=10. TS...

Re: API wind spectrum

Dear Dr. Jason, I already modified the code based on your suggestions, but the same warning appear again. 1) Standard deviation already changed to 1.94 m/s, and 0.0912 has been set as PLExp value. 2) The reason I set the RefHT to be 10-m previously because of the API requirement. Simulation abort wh...

Re: API wind spectrum

Dear Dr. Jason and Dr. Bonie, Based on my previous posting " https://wind.nrel.gov/forum/wind/viewtopic.php?f=4&t=306&start=60 ", I'm trying to generate API wind spectrum (NPD spectrum) to simulate the dynamic wind only case for OC4 DeepCwind Semi-Submersible FOWT by using TurbSim ...

Re: Wind & Wave data

Good day Dr. Jason and everyone, Recently, I just started using FAST v8 coupled with OrcaFlex for my research study, focused on OC4 DeepCwind FOWT. I'm trying to validate the results from paper entitled "Validation of a FAST semi-submersible floating wind turbine numerical model with DeepCwind ...

Re: FAST theory manual

Good day Dr. Jason,

Could you please send the unofficial FAST theory manual?
My email address: hanis.kamaruddin@hrbeu.edu.cn

Really appreciated it.

Thanks and regards,
Hanis
