local_aero2struct_forcesΒΆ
Maps the local aerodynamic forces at a given vertex to its corresponding structural node.
\[\begin{split}\mathbf{f}_{struct}^B &= C^{BG}\mathbf{f}_{i,aero}^G\\
\mathbf{m}_{struct}^B &= C^{BG}(\mathbf{m}_{i,aero}^G +
\tilde{\boldsymbol{\zeta}}^G\mathbf{f}_{i, aero}^G)\end{split}\]
