Cooldata - A Large-Scale Electronics Cooling 3D Flow Field Dataset

Cooldata is a large-scale electronics cooling dataset, containing over 60k stationary 3D flow fields for a diverse set of geometries, simulated with the commercial solver Simcenter STAR-CCM+. This library can be used to acccess the dataset and streamline its application in machine learning tasks.

Features

• Data Storage: Organized in folders containing .cgns files for compatibility with computational fluid dynamics tools.
• PyVista Integration: Access to dataset samples as PyVista objects for easy 3D visualization and manipulation.
• Graph Neural Network Support:
  • DGL Support:
    • Surface and volume data in mesh format.
    • 3D visualization of samples and predictions.
    • L2 loss computation and aggregate force evaluation for model training.
  • PyG Support: Implementing functionalities similar to DGL.
• Hugging Face Integration: Direct dataset loading from Hugging Face.
• Voxelized Flow Field Support: Facilitates image processing-based ML approaches.
• Comprehensive Metadata Accessibility: All metadata is accessible through the library.

Installation

Run

pip install cooldata

If you want to use the DGL support, you also need to install the DGL library, as documented here.

Example Usage

See the examples folder for a detailed example of how to use the library.

Roadmap

• Re-meshing with Random Point Sampling
• Inference of Surface Quantities from Volumetric Predictions
