# Extended 2D Dataset — NeurIPS Closure Challenge additions

Three new 2D cases added to the closure challenge from the **NASA TMR Collaborative Testing Challenge 2022** ([turb-prs2022](https://tmbwg.github.io/turbmodels/turb-prs2022.html)):

| Folder | Case | Required metrics |
|--------|------|------------------|
| `NASA_2DZP/`  | 2D Zero-Pressure-Gradient flat plate    | Cf(x); u⁺(log y⁺) at x=0.97 — vs theory |
| `NASA_ASJ/`   | Axisymmetric Subsonic Jet (M_jet ≈ 0.5) | u/Uj along axis; u/Uj and u'v'/Uj² at 5 stations — vs Bridges & Wernet PIV |
| `NASA_2DN00/` | NACA 0012 airfoil, α = 10/15/17/18°     | CL(α), CD vs CL, Cp(x/c), Cf(x/c upper) — vs Ladson + Gregory |

## Tools at this level
- `dat_to_csv.py` — converts NASA Tecplot zone-format `.dat` files to flat CSV (single `zone` column to preserve zone identity). Re-run after editing data:
  ```
  python dat_to_csv.py NASA_2DZP/baseline_komegasst NASA_2DZP/highfidelity \
                        NASA_ASJ/baseline_komegasst NASA_ASJ/highfidelity \
                        NASA_2DN00/baseline_komegasst NASA_2DN00/highfidelity
  ```

## Provenance
All `.dat` files copied from `OLD_NASA_CHALLENGE_SUBMISSION/finalModel/` (a baseline RANS submission to the 2022 NASA TMR Collaborative Testing Challenge), folders `baselineResults/` (k-ω SST baseline) and `NASAResults/` (theory / experiment) — see [plotFinal.py:10-14](OLD_NASA_CHALLENGE_SUBMISSION/finalModel/plotFinal.py#L10-L14) for the original mapping. The corresponding OpenFOAM cases live under `OLD_SETUPS/{00_2DZP, 02_ASJ, 04_2DN00}/00Baseline/`.

## TODO — full OpenFOAM `00Baseline_Data/` per case
The integral profiles + plots are complete. To match the structure of the existing 4 challenge cases (`ML4Fluids_2D_Dataset/{CBFS, NASA_2DWMH, PH_Breuer, Parm_PH_29}/00Baseline_Data/`), each new case still needs the converged k-ω SST OpenFOAM run packaged. Candidate sources:

| Case | OpenFOAM source | Notes |
|------|-----------------|-------|
| 2DZP  | `OLD_SETUPS/00_2DZP/00Baseline/simpleFoam/` | `kOmegaSST`, converged at t=10000 |
| ASJ   | `OLD_SETUPS/02_ASJ/BaselineRenzhi/Case/` or `00Baseline/CFDDomain/compressibleTransient/` | both `kOmegaSST`; pick one |
| 2DN00 | `OLD_SETUPS/04_2DN00/00Baseline/rhoSimpleFoam_Final/Case2/{10,15,17,18}_deg/` | only initial state — needs to be run, OR use the per-AoA cases under `OLD_NASA_CHALLENGE_SUBMISSION/finalModel/04_2DN00/` (latter were run with `propagationClassifierkOmegaSST` augmented model, not pure baseline) |
