Starter Kits
Each live benchmark includes a compact download from the showcase. You get design-of-experiments tables, example solved cases, and notes on how to run the simulation. These packs help you orient to the problem. Full training exports will follow.
Starter kits vs. full training data
Starter pack: design space, mesh, and sample cases. Full training exports coming soon. Use a kit to understand the design space, simulation setup, example solved cases, and holdout targets. Train on the complete dataset via Rescale AI Physics (or a future training pack) when available.

Shared kit layout
Both starter kit zips use the same top-level structure:
README.md # Overview and quick start doe/ cases.csv # Full design-of-experiments index + reference scalars holdout_scalars.csv # Five official holdout inputs + ground-truth scalars examples/ # Two curated solved cases (yaml + VTU each) simulation/ # Meshes, solver parameters, and run guidance spec/benchmark.json # Machine-readable benchmark definition submit/README.md # Notes on packaging results (upload coming soon)
File types
- CSV: DOE tables listing every training case and five holdout rows used for leaderboard scoring.
- YAML: Per-case metadata in case_data.yml (inputs and global scalars) and case_meta.yml (field list, point counts).
- VTU: ParaView-compatible mesh and nodal fields in case_data/case_data_0.vtu.
- STL: Reference geometry for inspection or local re-meshing. One shared mesh for airfoil. Two example hole sizes for plate.
- JSON: spec/benchmark.json summarizes inputs, outputs, solver, and holdout policy.
- Markdown: Solver-specific guides under simulation/ (how AoA or hole diameter is applied, expected post-processing fields, optional analytical checks).
Kits ship post-processed exports (VTU/STL), not native OpenFOAM case trees or CalculiX .inp decks from the original Rescale jobs.
2D Airfoil starter kit
Fluid dynamics benchmark with a fixed NACA-style mesh. Angle of attack is swept via freestream boundary conditions, not mesh rotation.
Design space
- Input: angle of attack AoA [°], 21 training values from 0° to 10° in 0.5° steps (doe/cases.csv)
- Fixed conditions: Re = 2×10⁶, U∞ = 29.2 m/s, OpenFOAM simpleFoam (simulation/parameters.yaml)
Included examples
- examples/case_aoa_0_train/ (AoA = 0°)
- examples/case_aoa_5_train/ (AoA = 5°)
- simulation/mesh/case_data.stl (shared geometry for all cases)
- simulation/openfoam/compute_freestream.py (Ux/Uy helper for any AoA)
Outputs
| Kind | Names | Where |
|---|---|---|
| Global scalars | Cl, Cd | case_data.yml, doe/*.csv |
| Nodal fields | Cp, Ux, Uy, p, nut, nuTilda | case_data_0.vtu (~21k points) |
Holdouts: five AoA values (0.25°, 2.75°, 4.75°, 7.25°, 9.25°) in doe/holdout_scalars.csv. Not all lie on the 0.5° training grid. See simulation/HOW_AoA_WORKS.md inside the zip.
Plate with Hole starter kit
Structural benchmark: central hole in a 200×50×5 mm plate under 10 MPa remote tension. Each case has its own mesh. Hole diameter is encoded in the geometry.
Design space
- Input: hole diameter [mm], 31 training values from 6 mm to 32 mm (doe/cases.csv)
- Fixed conditions: CalculiX 2.22, C3D10 elements, steel properties (simulation/parameters.yaml)
Included examples
- examples/case_hole_6mm_train/ (d = 6 mm)
- examples/case_hole_15mm_train/ (d ≈ 15 mm)
- simulation/mesh/case_data_hole_6mm.stl and case_data_hole_15mm.stl
- simulation/analytical/README.md (Peterson Kt cross-check)
Outputs
| Kind | Names | Where |
|---|---|---|
| Global scalars | max_von_mises_mpa, stress_concentration_factor | case_data.yml, doe/*.csv |
| Nodal fields | S_Mises, S_xx, S_yy, S_xy, U_x | case_data_0.vtu (~4.2k points) |
Holdouts: five diameters (9, 15.5, 19, 23.5, 29 mm) in doe/holdout_scalars.csv. See simulation/HOW_HOLE_DIAMETER_WORKS.md inside the zip.
Units
- Airfoil: SI units (m/s, Pa). AoA in degrees. Cl and Cd are dimensionless.
- Plate: geometry in mm, stress in MPa. Kt is dimensionless.
Scoring & holdouts
Holdout scalar targets in each kit match what the leaderboard evaluates. For how combined scores are computed from global accuracy and field R², see the evaluation protocol.
