A simple 2D discrete element method implementation.
This DEM code includes:
- Nearest-neighbor algorithm
- Hertz collision model
- Verlet time integration
- Core routines deferred to Numba
As of today, rolling movement is not implemented
Running a specific case requires to write an application in dem/app, and then to register it in dem/app/app.py. You can than call it from root directory doing python start.py <app_name>. Multiple app examples are provided in the dedicated directory, to be copied and adapted. Below are some simple sanity checks and a bit more advanced examples of what is possible with this small library.
