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

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_SIDA.json" file for more details on the dataset.
A sample Out-of-Distribution, "OOD.h5", is added as well, which covers a higher shock Mach number across 32 trajectories. For more details, refer to "metadata_SIDA_OOD.json".
Download:
The dataset can be downloaded, e.g., via huggingface-cli download.
