This repository contains code that simulates the physics of toppling dominoes as described in https://zmatt.net/domino-physics/

Basic simulation

domino-simulation.py simulates a line of toppling dominoes according to the assumptions in the blog post (no-slip, etc).

• Run python3 domino-simulation.py to run a first simulation, and then gradually inspect the script and edit the variables at the top.

LMGC90 simulation

For more complex 3D simulations, the lmgc90 directory contains scripts for running simulations using LMGC90, based on the work by David Cantor and Kajetan Wojtacki at https://github.com/dacg/3D_dominoes .

• Download and build LMGC90 (https://git-xen.lmgc.univ-montp2.fr/lmgc90/lmgc90_user/-/wikis/home)
• Set PYTHONPATH to point to the LMGC90 build directory
• Create a new empty directory for the output data
• From the new directory, run (for example) python3 ../generate.py and python3 ../run.py.
• The output file DISPLAY/lmgc90.pvd can be opened in paraview. In fact you can open it while the simulation is running and interrupt the simulation when time has progressed sufficiently.
