Tower aerodynamics

Wind & Water Rotor Aerodynamics

Hi all,

I notice in the ADTwr_CalcOutput routine that the relative velocity is calculated as:

V_rel = u%InflowOnTower(:,j) - u%TowerMotion%TranslationDisp(:,j) ! relative wind speed at tower node

Should it not be:

V_rel = u%InflowOnTower(:,j) - u%TowerMotion%TranslationVel(:,j) ! relative wind speed at tower node

or am I mistaken?

Thanks

Dear Aonghus,

This definitely looks like a bug. At least its easy to fix (as you identified). We’ll get this fixed in the next release of AeroDyn.

Best regards,
