Distributed blade property

2

Dear @Ran.Tu,

Here are my responses:

  1. Yes, AdjBlMs is a factor to (linearly) scale BMassDen. It is typically used if the integration of BMassDen along the blade yields a total blade mass that is slightly different than the expected value (due to discretization, integration error, or inexact properties).

  2. If the total blade mass is different than you expect, you can adjust AdjBlMs accordingly.

  3. PitchAxis is not used when AeroDyn v15 is enabled, e.g., as discussed in my post dated Jul 13, 2022 in the following forum topic: Stress Analysis of Blades and a Tower. The structural twist (StrcTwst) defines the orientation of the principle axes of bending

  4. The mode shapes for the NREL 5-MW baseline blade were not originally developed using BModes. See the following forum topic for a related discussion: Blade mode shapes with BModes.

Best regards,
