The best way to start contributing and collaborating with us is to send an email to blast.net.ml@gmail.com for onboarding instructions.

We also have a google forms that provides a checklist on your contribute data.

Before doing this checkout the standards and formats below.

Standards for BLASTNet

To ensure that all files available on BLASTNet has consistent file formats, we present some necessary standards for improved access:

1. All simulation datasets must contain [U,ρ,T,P,Y] to ensure that any additional variables can be easily post-processed. Provide chemkin or cantera files so that thermodynamic and transport properties can
2. X,Y,Z variables can be provided as a mathematical function for structured grids or a single share a single snapshot of the X,Y,Z values.
3. Shared simulation datasets must have a corresponding publication or conference submission.
4. All uncompressed files should be in little endian float32 binaries. A Colab/tutorial on how to read and write this format in python is provided here.
5. Datasets should be uploaded onto Kaggle (tutorial) to simplify batch access via a command line API.
6. Once files are shared with these standards are met, join BLASTNet by submitting the form above.

Metadata Format

Each submission on blastnet should have a global and local metadata in an info.json file which provides all the important information required to train an ML model. You can interact with these files here.

Global Metadata
