Arbitrary Shape

Hello Mohammad,

it depends on the definition of "arbitrary shape" :-) in general yes, there
are several options and some limitations:
- first of all, from design and implementation reasons, every single
standalone particle has to be convex
- Yade has implementation of polyhedral shapes, co modeling of cube is
possible (and easy actually).
- Yade can "clump" particles together, forming rigid cluster of particles.
With this approach, you can also create non-convex particles. Particles in
the clump can overlap, so you can **approximate** any arbitrary shape. Of
course, for larger amount of particles used, the better is the
approximation but it needs more computer resources.

If you need/want an example or has any other question, do not hesitate to
ask
cheers
