Abelian sandpile

This code allows to create, grow and visualize Abelian sandpiles.

For the description of the model see wiki or p. 52-53 in Bak (1996).

Setup

Install requirenemtns and build Cython code to make it run signingicantly faster.

pip install -r requirements.txt
python setup.py build_ext --inplace

Usage

Pour sand on the sandpile and save the sandpile after each 1000 grains.

./sandpile_main.py pour --verbose \
  --grid_size 200 --n_steps 1e5 --checkpoint_every 1e3 \
  --checkpoint_dir ./checkpoints  --store_avalanche_sizes

Plot the sandpile grid.

./sandpile_main.py plot \
  ./checkpoints/sandpile-000007470000.pckl.gz ./data/plots/
