# 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:
```bash
$ pip3 install pip --upgrade
```
Assume you have a Python 3 environment, to install Taichi:
```bash
$ pip3 install -U taichi
```
To run the demo:
```bash
$ 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
- ...
