Mesh is ignoring CAD altogether

@jousefm is correct, the domain is huge. The cells were so big they ‘missed’ your geometry. I reduced the bounding box to 1/4 the size and it picked the geometry up, but still looked severely under refined. So your options are to better refine the region surrounding the aircraft (either locally or globally) or reduce the domain size (or both).

Kind regards,
Darren
