fan-01 FAIL

FAN-01 low-pressure axial fan (EAA benchmark fan N1UG) analysed from its supplied CAD in the rig frame: the nine-blade rotor (tip radius 247.5) turns on a revolute joint about +y through (x, z) = (-400, 1515) inside the stationary duct (inlet nozzle, Ø500 bore, diffuser), with the shaft and the downstream hub disc turning with it. The stationary flow boundary the CAD lacks is derived: the chamber

A value its mesh ladder does not resolve is not evidence of performance; report.md gives each prediction's validation basis.
