Feature or improvement description
For BEM_Mod to be working properly, AeroDyn needs to change the AeroDyn Projection Method based on BEM_Mod. To achieve this, teh OpenFAST driver needs to set the AeroDyn Projection Method to -1 "automatic".

The projection method is an input to AeroDyn to allow the AeroDyn driver to change it (e.g. for vertical axis turbines).

We will likely be able to simplify the code logic in the future by:

  • Removing legacy nodal outputs
  • Removing outputs that do not have a well defined coordinate system ("x" and "y")
  • Always computing key geometrical quantities (toe, cant, drdz, R_li)
  • Renaming orientation annulus to orientation_momentum, and not using this coordinate for outputs.
