Jérôme Duriez proposed the following answer:
Hello,

To be sure interactions exist or not, I suggest to play with the
O.interactions functions (see the list at [1]) such as
O.interactions.withBody(), or with the "Inspector" of Graphical
Interface.

Once you're sure your problem is to create interactions, (re?)reading
[2] can not hurt. As you will see, interaction creation is not related
in any way with TriaxialStressController attribute such as
internalCompaction

Finally, all this could help you to figure out that your script misses
one "Bo1_Box_Aabb" [3] in the InsertionSortCollider() of your engines
(assuming your boundaries are of "Box" shapes, pick another "Bo1_*" if
it's not the case). This is mandatory for Box to be able to form
interactions, as per [2]

Check also the examples that use non-spherical particles.
