2D Airfoil · External aero
Engineering question: Can a surrogate reproduce lift, drag, and surface pressure across angles of attack on a 2D airfoil?
One airfoil, many angles of attack. Lift and drag for performance. Surface pressure for how the wing loads up. Classic teardrop cross section. The smallest step into external aero before a full wing or vehicle.

Angle of attack sweeps the operating point

Scope and limits
Comparability
2D external aero, not comparable with 3D vehicle or structural benchmarks. Mesh and Reynolds number are fixed within the open training corpus.
Ground truth
CFD from Rescale AI Physics training exports (OpenFOAM). Holdout cases use simulation truth for Cl, Cd, and nodal Cp.
Submissions
Published scores from models trained on the open 2D airfoil split and evaluated on shared holdout cases. Check rows to compare; expand for per-AoA predictions and Cp field metrics.
