# Simulation inputs & outputs

This folder bridges **“run FEA yourself”** and **“match our data format”**.

```

├── README.md                    ← you are here
├── HOW_HOLE_DIAMETER_WORKS.md   ← hole size is in the mesh (not a BC toggle)
├── parameters.yaml              ← fixed material, pressure, plate size
├── mesh/                        ← example STLs at 6 mm and ~15 mm holes
├── calculix/                    ← local run guidance
├── analytical/                  ← Peterson Kt reference
└── postprocessing/              ← expected VTU fields + scalars
```

**Workflow:** DOE in `doe/` → generate mesh per hole diameter → run CalculiX → postprocess like `examples/` → submit via `submit/`.
