Dear Satish,

You haven't really provided enough information to really comment. What conditions (e.g., wind speed) are you simulating to obtain the results you show in your table, and are these mean values of something else?

Dear Jason,

Thanks for your reply.

Wind condition corresponding to 1ETM with their respective rated wind speed and the loads are maximum (ULS unfactored) over time simulation of 630sec with TStart = 30sec. Wave loads of H = 10.6 and T = 11.54 s (regular waves).

Thanks,
Satish J

Dear Satish,

I'm not sure I can really comment on these results. It may help to break down the results into mean, standard deviation, and ultimate loads for wind only, wave only, and combined wind+wave to understand the trends a bit more.

Dear Jason,

Thanks for your reply.

Corresponding to parameters mentioned in the previous post. I have attached summary of results (Mean, SD, Ultimate loads) of all three turbines (NREL 5MW, DTU 10MW, IEA 15MW) for wind only, wave only, and combined wind+wave.

Thanks,
Satish J

Dear Satish,

Do you have any comment on these results? What makes sense to you and what does not?

Dear Jason,

Apologies for late reply.
Thanks for your response.

By looking at the summary of the results, can observe lower mean values for wind only (ETM) for DTU 10MW turbine. The trend for wave loads are gradually increasing which is as desired results. I re-ran the analysis to check whether anything is missing, but it resulted in the same. Apart from these, the rated wind speed which I considered are inline with the corresponding turbines. Will version of aerodyn affect the results? as DTU 10MW uses Aerodyn14. I have attached DTU 10 MW wind only configuration inputs.

Thanks,
Satish J

Dear Satish,

I'm glad the results you are obtaining make sense to you.

AeroDyn v14 is now quite old and we generally recommend upgrading to AeroDyn v15. We plan to deprecate AeroDyn v14 (removing it from OpenFAST) soon. The results may be OK with AeroDyn v14, but AeroDyn v15 contains a number of improvements over AeroDyn v14.
