BEM algorithm implementation according to AeroDyn v15

Dear @Chaozhi.Qiu,

Just a few comments:

  • Even if you don’t specify blade curvature in the AeroDyn input file, the blade can still have it when it deflects structurally.
  • The effect of blade curvature, whether input or from deflection, on the coordinate systems used in AeroDyn for the aerodynamic calculations and output reporting depends on how you’ve set BEM_Mod in AeroDyn. See AeroDyn’s coordinate system documentation for more information: 4.2.2. Coordinate systems — OpenFAST v4.1.0 documentation.
  • AeroDyn’s skewed wake correction is based on a generic skewed wake angle, expressing the total skew combining the effects of yaw and tilt.

Best regards,
