Friction and attraction forces can only produce granular effects up to a certain limit. To simulate piling and other interesting stacking effects, spherical particles need to be replaced by more complex structures and shapes. Particles hence need to become rigid bodies. In the provided video each particle becomes the centre of mass of a pyramidal shape represented by four surrounding lightweight particles. These surrounding particles do collide with each other, as well as interact with fluids or signed distance fields. Adjustable drag and restitution parameters allow for different body behaviours. The optional freezing feature will freeze bodies whose linear or angular velocity is below a certain threshold. Thus they come to rest more quickly and hence also speed up the simulation process. Stacking is handled using an iterative approach with user defined limits. Different shape presets can be chosen to simulate interesting piling effects. Since shapes can be arbitrary and regular DEM or SPH particles can become rigid bodies dynamically, we can theoretically move between physical conditions. (This feature is in development.)
