DiffPhyCon 2D Jellyfish Dataset
This repository is an archival mirror of the official 2D Jellyfish dataset released by AI4Science-WestlakeU for the NeurIPS 2024 paper “DiffPhyCon: A Generative Approach to Control Complex Physical Systems.”
The dataset was not generated or authored by bcTiann. It is mirrored here to
support reproducible DiffPhyCon baseline and Flow Matching experiments. The
data values have not been modified; only lossless tar sharding was applied to
make storage and transfer through the Hugging Face Hub reliable.

Contents
train_data: 30,000 simulations.test_data: 200 simulations.- Per-simulation fluid states, forces, boundaries, opening-angle controls, and merged boundary representations.
- Training and test normalization metadata.
To avoid Hub commit-rate limits from roughly 150,000 source files, the files are stored in lossless tar shards:
shards/train_states_*.tar: the 30,000 training-state files, split into 2,000 simulations per shard.shards/train_auxiliary.tar: training forces, boundaries, controls, merged masks, and normalization metadata.shards/test_data.tar: the complete 200-simulation test split.SHA256SUMS: archive integrity checksums.
Extracting the archives recreates the original train_data and test_data
directory layout. The main source subdirectories are states, forces,
bdry128, bdry64, bdry_head_thetas, and
bdry_merged_mask_offsets.
License and redistribution status
The official DiffPhyCon source-code repository is distributed under the MIT License. However, the Jellyfish dataset and checkpoints are distributed externally through Google Drive, and no separate dataset license was found in the official repository README or in the downloaded dataset package.
For that reason, this mirror does not assert that the dataset itself is
MIT-licensed, and the Hugging Face metadata uses license: other. This public
archival mirror preserves explicit attribution to the original DiffPhyCon
authors; users should consult the original authors before further
redistribution or commercial use.
