Taichi DEM

A minimal DEM simulation demo written in Taichi.

To implement your own version, click the "Use this template" button on this page and simply modify the dem.py script.

Installation

Make sure your pip is up-to-date:

$ pip3 install pip --upgrade

Assume you have a Python 3 environment, to install Taichi:

$ pip3 install -U taichi

To run the demo:

$ python dem.py

Assumptions

The dem.py implements a minimal DEM solver with the following assumptions:

  • All paricles are round circles with variable radius.
  • Only the normal force between particles is considered - the tangential force is not included.
  • The deformation of the particles is not included.
  • Ignore the angular momentum of the particle and only consider the translation of the particle.

Open missions

There are plenty of room for hacking! We suggest a few of them for you to start with:

  • Reduce the neighborhood search region from the 3x3 grid cells to only 5 grid cells
  • Support more particle geometries
  • Implement angular momentum of the particles
  • Include tangential forces
  • ...
