Intended use and limitations

The checkpoints are research artifacts for segmentation of shocks and vortex-core candidates in two-dimensional compressible CFD fields following the documented input contract. They are not a flow solver, a substitute for CFD convergence checks, or a universal detector.

Training supervision is physics-derived and weak. CFD Dice values measure agreement with corrected weak references, not human ground truth. Analytic vortex and SU2-ray evaluations are independent bounded controls but do not measure complete post-shock vortex accuracy or full-front precision. Sigmoid scores are not independently calibrated probabilities. Near-wall vorticity, strong shear, contact-like layers, numerical oscillations and unfamiliar grids remain possible failure modes. Users must inspect overlays and preserve the separation among ML-only, physics-only and hybrid products.
