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_Modin 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,
