Re: Free decay analysis and natural frequency

Dear Jason, I performed free decay simulations with flexible rotor and rigid tower without BeamDyn, hence with platformDOFs+(FlapDOF+EdgeDOF) activated, and the results are extremely close to flexible and rigid model for both pitch and surge. I will leave as attachment the input file I used for the ...

Re: Free decay analysis and natural frequency

Dear All, I performed free decay simulations for a 10MW OffShore RWT in order to verify the mode frequencies(in particular Pitch and Surge) of the model. The simulations were performed with CompElast, CompHydro and CompMooring active only, where HydroDyn reproduced still water enviroment. For what c...

Computational differences with ED+BD+ADv15 versus ED+ADv15

Hi, I need clarifications regarding the computational differences using ElastoDyn+AeroDyn_v15 and ElastoDyn+AeroDyn_v15+BeamDyn. I'm not understanding the differences occurred in the steady state values of the collective pitch (attachment) considering an isotropic blade modelled throught FAST with s...

Coordinates system conventions for DTU 10MW RWT vs. FAST's coordinates system conventions

Hi, I need clarifications about the relationships between coordinates system of DTU 10MW RWT and FAST's coordinate system. In particular I'm confused for what concern the pitch rotation: in order to perform correct computation with FAST I need to add the structual twist of the blade (obtained from D...

Re: FAST THEORY

Dear Dr. Jonkman,

If possible, I would like to get the unofficial FAST theory manual.

Thanks in advance for your help.
