Description:
This Dataset includes 128 trajectories of time-dependent Laser-Induced Droplet Explosion (LIDE). Using a Finite Volume solver, we solve the two-dimensional (2D) axisymmetric compressible Euler equations for this multiphase problem.

- PDE: 2D axisymmetric compressible Euler equations,
- created: 08-2025,
- time_dependent: true,
- include_initial_state: true,
Spatiotemporal Information:
- num_trajectories: 128,
- num_time_steps: 201,
- num_channels: 6,
- channel_names: ["density", "pressure", "velocity_x", "velocity_y", "schlieren", "energy"],
- spatial_dimensions: 2,
- spatial_grid_size: [256, 256],
- dx=dy: 1.250000000e-07
Boundary conditions:

- north: ZeroGradient
Two separet files, "train.h5" and "test.h5", are provided. The former includes 96 trajectories for training and validation; the latter covers the 32 remaining trajectories for inference only.
Refer to the "metadat_LIDE.json" file for more details on the dataset.
A sample Out-of-Distribution, "OOD.h5", is added as well, which covers higher pressure values across 32 trajectories. For more details, refer to "metadata_LIDE_OOD.json".
Download:
The dataset can be downloaded, e.g., via huggingface-cli download.
huggingface-cli download FluidVerse/LIDE --repo-type dataset --local-dir <LOCAL_DIR>
Assembly:
After download, data parts for each file, train.h5, test.h5, or OOD.h5, can be assembled into a single HDF5 file using the provided assemble.py script. Use it as follows:
python ./assemble.py --folder_path <FOLDER_PATH> --output_path <OUTPUT_PATH>
Extra Data Generation:
Use the instructions inside the generation script, "generator.py", for creating larger datasets. This script runs the solver specified in the "metadata_LIDE.json" file.
