Built for design A/B: relative accuracy between variants (see PHYSICS_AUDIT) rather than a certified aerodynamic result. The residual/convergence verdict is a deterministic metric; a low residual means the flow settled.

Visualization

pressure streamlines vectors

vortex cores particles

colour by map

slice

streamlines vectors

equal-length vectors easier to read direction in slow flow
