 # Wind Tunnel Dataset
+The Wind Tunnel Dataset contains 20,000 [OpenFOAM](https://www.openfoam.com/) simulations of 1,000 unique automobile-like objects placed in a virtual wind tunnel. 
+Each object is simulated under 20 distinct conditions: 4 random wind speeds ranging from 10 to 50 m/s, and 5 rotation angles (0°, 180° and 3 random angles).
+To ensure stable and reliable results, each simulation runs for 300 iterations.
+The meshes for these automobile-like objects were generated using the [Instant Mesh model](https://github.com/TencentARC/InstantMesh) and sourced from the [Stanford Cars Dataset](https://www.kaggle.com/datasets/jessicali9530/stanford-cars-dataset).
+The entire dataset of 20,000 simulations is organized into three subsets: 70% for training, 20% for validation, and 10% for testing.
 
-The Wind Tunnel Dataset contains 20,000 wind tunnel simulations, organized into three subsets: 70% training, 20% validation, and 10% test.
-The simulations were generated using [OpenFOAM](https://www.openfoam.com/) and [Inductiva](https://inductiva.ai/) and are based on 1,000 unique objects, each with 20 variations.
-The simulations cover 4 wind speeds and 5 different rotation angles, with each simulation running for 300 iterations.
-The input object meshes were generated using the [Instant Meshes model](https://github.com/TencentARC/InstantMesh) and the [Stanford Cars Dataset](https://www.kaggle.com/datasets/jessicali9530/stanford-cars-dataset).
-
+The data generation process itself was orchestrated using the [Inductiva API](https://inductiva.ai/), which allowed us to run hundreds of OpenFOAM simulations in parallel on the cloud.

 ### Dataset Files
+Each simulation in the Wind Tunnel Dataset is accompanied by several key files that provide both input and output data. 
+Here’s a breakdown of the files included in each simulation:
 
 - **input_mesh.obj**: OBJ file with the input mesh.
 - **openfoam_mesh.obj**: OBJ file with the OpenFOAM mesh.
 - **pressure_field_mesh.vtk**: VTK file with the pressure field data.
 - **streamlines_mesh.ply**: PLY file with the streamlines.
-- **metadata.json**: JSON with metadata such as input parameters and some output results.
+- **metadata.json**: JSON with metadata about the input parameters and about some output results such as the force coefficients (obtained via simulation) and the path of the output files.
