Generate a Dataset

AutoSim uses Hydra configs to instantiate simulators and generate train, validation, and test splits.

List available simulator configs:

uv run autosim list

Generate a small dataset with the advection-diffusion simulator:

uv run autosim \
  simulator=spatiotemporal/advection_diffusion \
  simulator.n=16 simulator.T=0.2 simulator.dt=0.1 \
  dataset.n_train=1 dataset.n_valid=1 dataset.n_test=1

The generated dataset contains train, valid, and test directories with a data.pt payload for each split.
