CFDBench: cylinder wake

Goal

Evaluate unsteady wake prediction, phase accuracy, and rollout stability under parameter and geometry changes.

Recommended models

PIBERT, FourierFlow, FNO/F-FNO, PDE-Refiner, Transolver, UPT, INC for hybrid correction, and a numerical baseline.

Metrics

Field error, drag/lift coefficients when available, Strouhal number, phase drift, autocorrelation, kinetic-energy spectrum, stable horizon, and blow-up rate.
