# 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. |

> 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`. |
|
|
|
|
|
```bash |
|
|
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: |
|
|
```bash |
|
|
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. |
