Lots of Simulations

Installation

You will need to install uv and ffmpeg to run AutoSim.

git clone https://github.com/alan-turing-institute/autosim
cd autosim
uv sync

AutoSim comes with a number of bundled simulators for different physical phenomena. You can list these with:

uv run autosim list

Generate training data

To generate a tiny dataset with the advection-diffusion simulator, run:

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

Do check out the documentation for more information on configuration options and simulators!
