Fig. 7 Mapping of discretised aerodynamic forces onto the FE beam mesh according to the closest-node approach for a coarse and a fine FE mesh. When using a very fine FE discretisation, loads are practically projected perpendicular to the beam’s elastic axis (image from [Dett19]).

Fig. 8 Comparison of load mapping schemes for a swept wing (image from [Dett19])

Fig. 9 Projection of off-axis loads onto a cantilever beam inclined with respect to the global coordinate system. The global coordinate system (blue axes) and the beam-local coordinate system (green axes) do not coincide. The off-axis loads can be projected onto the beam axis either using a parallel-to-X or a closest-element (closest-node) approach (image from [Dett19]).
