Dear @Andre.White,
OK, thanks for clarifying. I’m glad your parked modeling issue is solved.
Regarding the large blade deflection at high yaw misalignments in the parked or idling condition, sounds like the problem we’ve seen before for other wind turbines, as discussed in the following forum topic: Designing for yaw errors using FAST. Indeed, increasing the blade structural damping is a common solution.
Best regards,
