CFD drag, lift, and shedding evaluation

FIG 1.0 Aero quantities

Loads and shedding frequency, scored directly.

Published 9 Jul 2026 · Updated 4 Aug 2026

Across the published horizon ladder the model reproduces the loads to 0.5–1.6% (force RelL2 0.001–0.016). The measured shedding frequency on the published comparison is 0.128. Loads here are model-derived diagnostics, not wind-tunnel measurements.

Aero-quantity evaluation: drag and lift coefficients for solver and model, and field versus load error — Drag, lift, and error location across three held-out geometries (Re 104 to 355) · the mid-horizon hump lives in the vorticity phase (0.052), not the loads (0.005)

St 0.128 (solver) = 0.128 (model) · illustrative rendering of the measured frequency match
