Hi Leonard,

any code to the example would be helpful. Otherwise, there are unlimited
possibilities.

What would you call uncertainty, because two issue are mentioned:non-
smoothness, and repeatability.

I can only guess that non-smoothness can be caused by relatively big
grains and high angularity of particles (or rolling friction). Different
results of 'the same' simulation, may be related to changing initial
configuration of the particles.

It is just guess. It is hard to discuss it without more concrete
example.

Cheers,
Karol
