AirfRANS: geometry and operating-condition generalization

Goal

Predict steady RANS fields and integral forces on unseen airfoils, Reynolds numbers, and angles of attack.

Recommended models

Transolver, GINO, Geo-FNO, UPT, DoMINO, MeshGraphNets, and PointNet/GraphSAGE baselines.

Metrics

Volume-field error, surface pressure, wall shear, lift, drag, boundary-layer profiles, and OOD degradation.

Leakage control

Hold out entire geometry families, not random mesh points. Preserve the official extrapolation tasks.
