Dear @Andre.White,

Here are my responses:

  1. Regardless of the load case, you can always set PtrmYIner to represent the otherwise unconsidered rotational inertia of the undeflected tower about its centerline. But it is necessary to set PtfmYIner nonzero when PtfmYDOF = YawDOF = TRUE.
  2. I’m not sure which “error” you are referring to. But I would not expect that you would set YawDOF or PtfmYDOF differently for cases with and without yaw misalignment.
  3. When YawDOF = True, I would always recommend setting YawNeut = NacYaw unless you are purposely trying model a case where the nacelle-yaw snaps back to its neutral state.
  4. See 3. This applies for cases with and without yaw misalignment.

Best regards,
