# FuXi-CFD model (ONNX)

This folder contains the exported ONNX weights for FuXi-CFD inference.

- `fuxicfd_model.onnx`: ONNX model weights

## Input / Output signature (expected)
- Input tensor: `(1, C, H, W)` where `C=4`, `H=W=300`
  - Channel order: `[u_100m, v_100m, dem, roughness]`
- Output tensor: `(1, 27, 4, 300, 300)`
  - Output variable order: `[u, v, w, k]`

See `inference_example/README.md` for a runnable end-to-end inference demo.
