| # 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. | |
| ## Layout | |
| ``` | |
| NASA_2DWMH/ | |
| └── highfidelity/ | |
| └── velocity_at_evaluation_points.csv columns: x, y, z, Ux, Uy, Uz | |
| ``` | |
| ## 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. | |
