Dear Dr. Jason Jonkman.
In FAST v8.12 manual, it was wrote that blade-shear, -extensional, and-torsion DOFs are included.
Does it mean that the torsional and axial stiffness of blade are considered in the FAST simulation if they are entered in blade data input file?
Dear HyoungChul Kim,
The blade-shear, -extensional, and -torsion DOFs (as well as bending) are included in the BeamDyn module of FAST v8 (as other as other features not available in the ElastoDyn module). Included in the input files of BeamDyn are the full 6x6 cross-sectional mass and stiffness matrices.
Dear Dr. Jason Jonkman
Thank you for your time!
