NASA_2DWMH (v1 case)
Held-out test case from the original Closure Challenge v1 release. Reference DNS/LES velocity field sampled at 1000 evaluation points.

Submission format
Submitters provide predicted velocity vectors at the same 1000 (x, y, z) coordinates. The score is the mean Euclidean error normalised by the mean reference velocity magnitude (paper Eq. 1).
Provenance
The 1000 evaluation points and reference U values are reproduced from the original Closure Challenge v1 distribution under the same license as the upstream high-fidelity source.
