Dear all, I have known that through the MBC toolbox can calculate the natural frequency of the rotor (for example progressive and regressive modes), however I want to know how...
Dear @jjonkman, I have read a post on the forum about "Aerodynamic center offset effects on blade torsion" (https://forums.nrel.gov/t/aerodynamic-center-offset-effects-on-blade-torsion/4841), and I have known that the offset between the aerodynamic center...
Dear @jjonkman, I modified the `BlSwpAC` in the "IEA-15-240-RWT_AeroDyn15_blade.dat" file to investigate the swept design on the performance of the IEA-15 MW wind turbine. The modified "IEA-15-240-RWT_AeroDyn15_blade.dat" file is shown...
Dear @jjonkman, I want to implement an user-defined pitch setting series in openfast. To be more specifically, I want to make the pitch angle of the blades change according to...
Dear all, I want to test the effect of servo control of the IEA-15 MW wind turbine operated a prescribed sinusoidal variation wind (same as the inflow condition of prescribed...
Dear all, I want to conduct a special simulation with continue step increase rotational speed of rotor in OpenFAST. I have known how to impose step increase wind velocity in...
Dear @jjonkman As we know, the time step of the BeamDyn is usually smaller than OLAF, so how did the aerodynamic load used for BeamDyn is calculated between two time...
