    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

> 1- I still have the same issue of spheres passing through the facet. What could be the issue?
> 2- When you say "box instead of facet", are you referring to geom.facetBox or aabbWalls?

I did not meant box as a shape of the boundary, but utils.box as a bodies forming the boundary.
Facets have zero thickness, so small particles can "jump" through the facet without contact detection.
This should not be the case for utils.box, which would have non-zero thickness and such "jump" would be more difficult.

> 3- How to check if there is sphere overlap at the initial packing
(i.e. iteration= 0)?

O.step()
print(len(i for i in O.interactions))

cheers
Jan
