Short summary
This study addresses the challenges of applying aerodynamic loads to a multibody reduced-order model based on solid finite elements. This model differs from the beam models typically used in wind turbine aeroelastic simulations by relying on a higher-fidelity finite element model. The results show that the proposed load application methodology produces accurate structural responses, while also identifying best practices for this process.
