Hi,

To rephrase what your computer already told you:

- use of BoxFactory involves a hidden call to
InsertionSortCollider::probeBoundingVolume [*]

- that function does not support periodic boundaries [**]

=> you indeed need an alternative script, or to modify source code and
extend InsertionSortCollider::probeBoundingVolume to periodic boundaries
(which would improve Yade)

[**] https://gitlab.com/yade-dev/trunk/-/blob/a37d9fd2f20f102fd277ac6aaaf52df8fbeb18f0/pkg/common/InsertionSortCollider.cpp#L193
