# FuXi-CFD 

This repository contains:

1) **Model weights** (ONNX) under `model/`
2) A **runnable inference example** under `inference_example/`

## Quick start (inference example)

```bash
cd inference_example
python scripts/infer.py \
  --model ../model/fuxicfd_model.onnx \
  --input data/inputs.npz \
  --output data/prediction.npz
```

Outputs are saved as `data/prediction.npz` with keys: `u, v, w, k` (each shape `(27, 300, 300)`).

## Folder structure

- `model/`: exported ONNX weights + model documentation
- `inference_example/`: end-to-end preprocessing → ONNX → postprocessing demo
  - `data/`: sample input/output
  - `normalization/`: scaler parameters and documentation
  - `scripts/`: runnable scripts and notebooks
  - `utils/`: reusable helper functions
