setExternalAction
Quote from Charles Li on 15. February 2026, 14:26Dear David,
I currently want to apply external forces in real time to different locations of the wind turbine through the setExternalAction function, but the official documentation only provides the following locations.
CAB_<X>, MOO_<X>, TRQ, BLD_<X>, STR_<X>_<Y>, AFC_<X>_<Y>, SUB_<X>, JNT_<X>, HUBFIXED, NAC.
I would like to ask how to set the char id in void setExternalAction(char *action, char *id, double val, double pos, char dir, bool isLocal, int num) if I want to apply this force to other positions on the tower (such as 0.5H or 0.8H, where H is the tower height).
I look forward to your reply.
Thanks and Regards,
Charles

the location ID to use for the tower is TWR.
I saw thats its missing from the docs and I just added it.
To change the normalized position along the tower you have to use the pos argument of setExternalAction().
