+## Dataset Description
+
+CFD Benchmark is a comprehensive benchmark dataset for training and evaluating neural PDE solvers. It contains six standard tasks on regular grids, structured grids, and irregular geometries. The dataset was used for unified evaluation in the ICML 2024 paper *Transolver*, and some of its data originates from the FNO and Geo-FNO works.
+
+The dataset contains six subsets: `airfoil`, `darcy`, `elasticity`, `ns`, `pipe`, and `plas`.
+
+Paper: [Transolver: A Fast Transformer Solver for PDEs on General Geometries](https://proceedings.mlr.press/v235/wu24r.html)
+
+## Supported Tasks
+
+| Subset | Task |
+|---|---|
+| `airfoil` | Steady-state airfoil flow-field prediction. |
+| `darcy` | Darcy equation solution-field prediction. |
+| `elasticity` | Stress prediction for random-cell structures. |
+| `ns` | Navier-Stokes flow-field time-series prediction. |
+| `pipe` | Steady-state pipe flow-field prediction. |
+| `plas` | Plasticity dynamics response prediction. |
+
+## Dataset Format and Structure
+
+The data is located in the `data/` directory and organized by task:
+
+```text
+data/
+  airfoil/
+  darcy/
+  elasticity/
+  ns/
+  pipe/
+  plas/
+```
+
+The data files use NumPy NPY and MATLAB v5 formats. The Airfoil, Pipe, and Elasticity subsets contain grid coordinates, geometry, or flow-field arrays; the Darcy and Navier-Stokes subsets use MATLAB files to store coefficient and solution fields; and the Plasticity subset contains load inputs and response outputs over multiple time steps.
+
+See `metadata/schema.yaml` for the shape and dtype of each file and the MATLAB variable structures.
+
+## How to Use the Dataset
+
+This dataset has been adapted for the `OneScience-Sugon/CFD_Benchmark` model. Download the dataset and model:
+
+```bash
+hf download --dataset OneScience-Sugon/cfd_benchmark --local-dir ./cfd_benchmark
+hf download --model OneScience-Sugon/CFD_Benchmark --local-dir ./CFD_Benchmark
+```
+
+Quickly check file presence, sizes, and readability:
+
+```bash
+cd cfd_benchmark
+python scripts/validate_dataset.py --skip-sha256
+```
+
+Remove `--skip-sha256` to perform a complete SHA256 validation.

+## 数据集描述
+
+CFD Benchmark 是用于神经 PDE 求解器训练和评测的综合基准数据集，包含规则网格、结构化网格和非规则几何上的六类标准任务。该数据集被 ICML 2024 论文 *Transolver* 用于统一评测，部分数据来源于 FNO 和 Geo-FNO 工作。
+
+数据集包含 `airfoil`、`darcy`、`elasticity`、`ns`、`pipe` 和 `plas` 六个子集。
+
+论文：[Transolver: A Fast Transformer Solver for PDEs on General Geometries](https://proceedings.mlr.press/v235/wu24r.html)
+
+## 数据集支持的任务
+
+| 子集 | 任务 |
+|---|---|
+| `airfoil` | 翼型稳态流场预测。 |
+| `darcy` | Darcy 方程解场预测。 |
+| `elasticity` | 随机单元结构应力预测。 |
+| `ns` | Navier-Stokes 流场时间序列预测。 |
+| `pipe` | 管道稳态流场预测。 |
+| `plas` | 塑性动力学响应预测。 |
+
+## 数据集的格式和结构
+
+数据位于 `data/` 目录，并按任务划分：
+
+```text
+data/
+  airfoil/
+  darcy/
+  elasticity/
+  ns/
+  pipe/
+  plas/
+```
+
+数据文件采用 NumPy NPY 和 MATLAB v5 格式。Airfoil、Pipe 和 Elasticity 子集包含网格坐标、几何或流场数组；Darcy 和 Navier-Stokes 子集使用 MATLAB 文件保存系数场和解场；Plasticity 子集包含载荷输入及多时间步响应输出。
+
+各文件的 shape、dtype 和 MATLAB 变量结构以 `metadata/schema.yaml` 为准。
+
+## 数据集使用方式
+
+本数据集适配 `OneScience-Sugon/CFD_Benchmark` 模型。下载数据集和模型：
+
+```bash
+hf download --dataset OneScience-Sugon/cfd_benchmark --local-dir ./cfd_benchmark
+hf download --model OneScience-Sugon/CFD_Benchmark --local-dir ./CFD_Benchmark
+```
+
+快速检查文件存在性、大小和可读性：
+
+```bash
+cd cfd_benchmark
+python scripts/validate_dataset.py --skip-sha256
+```
+
+移除 `--skip-sha256` 可执行完整 SHA256 校验。
