Extract blade tip torsional deformation from the Wiener-Milenković parameters in BeamDyn

Dear all,

I am trying to extract the blade tip torsional deformation from the outputs of BeamDyn. The parameters "TipRdxr", "TipRDyr" and "TipRDzr" in BeamDyn output are Wiener-Milenković rotation parameters, which corresponds to c1, c2 and c3 in the equation(5.17) in BeamDyn User's Guide. Now I can calculate the rotation tensor R(c), and then extract the Euler angles (yaw, pitch and roll) from it. My question is that the Euler angle which represents the rotation around the blade pitch axis is the blade torsional deformation?

I would be appreciated for your reply.

Best regards.
