eVTOL and rotorcraft cases fail when the mesh treats every region like a cruise wing. HENMESH Phase 6.4 Rotorcraft and 6.5 eVTOL workbenches add MRF and industrial overset zone prep so rotary and transition physics get local resolution.
Name the question
Hover download, transition buffet, or cruise propeller efficiency? Zone refinement follows the question — not a single global density.
Rotor and propeller disks
Mark disk or blade regions early so surface and volume sizing cluster where induced velocities matter for HENFLOW rotorcraft/propeller modules. Suite export carries MRF/overset meta into the solver.
Keep the wing honest
Winged eVTOL still needs LE/TE discipline from fixed-wing aero. Do not starve the wing to feed the rotor box.
Engineering takeaway
Rotary cases need named zones and a workbenchTag; anonymous fine meshes hide the trade.
How HENMESH helps you act
Run Rotorcraft / eVTOL workbenches, gate quality, suite-export to HENFLOW rotorcraft or propeller campaigns.
