Re: NREL 5MW Reference WT - Power Curve

Dear Jason,

I'm running OpenFAST 2.4.0 with AeroDyn15.
Your assumption is right: I've just run a couple of simulations around the rated speed switching to AeroDyn14, and the results are indeed consistent with the 2009 report.

Thank you for pointing me in the right direction!

NREL 5MW Reference WT - Power Curve

Dear all, I've been trying to reproduce the power curve and the data shown in Figure 9-1 of the 2009 report of the NREL 5MW Reference Wind Turbine. I've run simulations for the onshore model at different steady and homogeneus (null shear exponent) wind speeds. Results look fine, yet the rated wind s...

Re: FAST theory manual

Dear Dr. Jonkman,

If possible, I'd like to get the unofficial FAST theory manual as well.

Best Regards,

Re: Blade Azimuth, Tower Potential Flow and Shaft Tilt

I guess the answer is provided in this topic: viewtopic.php?f=4&t=1680 . I'm still leaving this as a reference for searchers, if it can be useful. Otherwise it can be deleted.

Blade Azimuth, Tower Potential Flow and Shaft Tilt

Dear all, I'm just starting to use AeroDyn to become familiar with the software before switching to OpenFAST. I've noticed some strange behaviour of blade azimuth. Since the rotor speed is fixed to 12.1 rpm, I am expecting to find a linear behaviour of the blade azimuth; however, the actual behaviou...

Re: OpenFast Regression tests

Dear all, I compiled openfast via Visual Studio as explained in the documentation. I am using Visual Studio 2019 and Intel Parallel Studio 2020. I did the regression tests, of which 19 passed and 10 failed (including the linear ones, which, I read, do not count), as shown in the image below. Most of...
