Re: why FAST8.12 is not available to download??

Hi Jason,

Could you please also send me a link to download FASTV8.09 for the linux version? I am planning to run a few more simulations but also want to be consistent with the previous ones, which are completed with FAST v8.09.

Thanks very much!

Re: Campbell Diagram & MBC3 output relation

Dear Jason, I am trying to get the natural frequencies of the tower and blade. So I started with linearization analysis with FAST V7 and post process the results with MBC & CampbellDiagram.xls. I linearized FAST at different rotor speed (0 -10 RPM), analyze them and got the Campbell Diagram. I f...

Re: Free decay result

Dear Jason, Thanks for your prompt reply. The document you provided is really helpful! I am using FAST V8.09 for my work,not the latest one. I will check with the latest version(V8.10) later to see if there is any difference. I go through the HydroDyn manual and double checked my model. In summary, ...

Re: Free decay result

Dear Jason, I am working on a larger wind turbine (compared to NREL 5MW) mounted on a scaled-up OC4-semi submersible platform now. A divergence problem came up when I am trying to run the free-decay simulation for the global system. Here is what we did: We are trying to optimize the size of the plat...

Re: WAMIT

Dear Jason, I have a question about WAMIT HydroData (*. 1 and *.3) files. Is the first column (" PER" column ) in the HydroData must be period in second? In the WAMIT input file, I specified the IPERIN = 2 (2: frequency in rad/sec). As a result my first column of WAMIT output file is also ...

Re: OC3-Hywind RAOs

Hi guys, I am also trying to reproduce the results in the ISOPE paper: Investigation of Response Amplitude Operators for Floating Offshore Wind Turbines. But I encountered a problem with the FAST running. Could anyone help me out? I am using the OC3-Hywind model coming with the FAST V8. I added the ...

Force-Displacement relationship of OC4 DeepCwind Mooring sys

Hi everyone, I am reproducing the force-displacement relationship of OC4 DeepCwind Model just as what Dr. Jonkman did in the reference paper: Definition of the Semisubmersible Floating System for Phase II of OC4_5Dec2012 . I get the same results as Dr. Jonkman but I have a question about the Pitch r...
