F2A is an aero-hydro-servo-elastic tool developed based on AQWA by Yang Yang, a postdoctoral research associate in Liverpool John Moores University for performing fully coupled analysis of floating offshore wind turbines (FOWT). The aero-servo-elastic simulation capabilities are fully implemented within the user_force64.dll which is a built-in DLL of AQWA for external force calculation. For a coupled analysis of a floating offshore wind turbine subjected to wind, wave and current loadings, the aerodynamic loads acting on the rotor, the elastic responses of the blades and tower, and the servo-control are examined through the DLL, considering the influence from the platform motions. The platform position, velocity and acceleration at each degree of freedom are passed into the DLL to update the kinematics of the upper structures. Before being passed into DLL, these terms are transformed from the inertial coordinate system to the local coordinate system of the platform.
Hi Yang, I try to run the simulation withw F2A but i don't understand how I can solve this error wich appears when I run the simulation. Have you any idea about?. thanks for your work.
the error is: Error: FF wind array was exhausted at 27.825 seconds (trying to access data at 37.569 seconds).
Error getting velocity in AeroDyn/AD_WindVelocityWithDisturbance().
Hi I am sorry that I did not notice the issue here. I am not familiar with the interactions in Github.
This problem is caused due to the short wind data defined in AeroDyn.ipt. Because I cannot upload a full-length wind data file to the repository due to the size limit of Github. You need to re-run TurbSim to generate a full-length wind data file and the problem will be solved.
