Feature or improvement description
The current documentation has issues showing the beam element formulation used in SubDyn: https://openfast.readthedocs.io/en/main/source/user/subdyn/theory.html#beam-element-formulation
For the stiffness matrix, not all the diagonal coefficients are shown and the mass matrix seems to provide the stiffness matrix for most part of it. See below for reference:
This is quite confusing for the OpenFAST users that want to understand the beam theory used in SubDyn.
