MLS_MPM_CPIC

Introduction

An implementation of the CPIC(Compatible Particle-in-Cell) method with Taichi lang where MLS-MPM and rigid body collision techniques are adopted.
These cases are mainly based on the paper A Moving Least Squares Material Point Method with Displacement Discontinuity and Two-Way Rigid Body Coupling.
Please install Python 3.x and corresponding Taichi package for running the scripts presented here.
For installing Taichi, please refer to Taichi Doc for details.

Cutting Thin

In this case, a suspended solid block is cut by a thin plate.
No penalty force and impulse on the rigid body are implemented.

Rotating Fan

In this case, a rotating fan interacts with granular particles flowing down.
The number of fan blades and its initial angular velocity can be adjusted.
