Hi @wjsjtu123,
lbm_length
is 40% of the longest side of the simulation box (let's say 300 LBM cells long).fuselage->get_bounding_box_size().x
is the length of the fuselage mesh, as it is loaded from.stl
coordinates (could be 10 for example); the.x
component here is the length because the mesh is rotated such that its length is along the x-axisscale
is the ratio of the two- applying
scale
to thefuselage
mesh first divides its length by itself (fuselage->get_bounding_box_size().x
) so that it now is 1 LBM cell long, and then multiplies bylbm_length
to make it 300 LBM cells long - this allows to make the mesh always the same size within the LBM simulation box, regardless how large or small it was in
.stl
coordinates
Kind regards,
