Hi,

This code essentially erases the contacts between different
agglomerates, with the O.interactions.erase() line.

Whether these inter-agglomerate contacts are re-created, and with wich
type, during the subsequent O.step() strongly depends on the geometry of
your problem, and of your O.engines list, which you did not tell us
(looking at the mentioned simulation.py did not help me: there is no
CohFrictMat/CohFrictPhys therein ;-) )

Note that you can easily check the type of interactions with e.g.:

for i in O.interactions:
 b1,b2 = [O.bodies[ii] for ii in (i.id1,i.id2)]
 if b1.agglomerate != b2.agglomerate:
   print i.phys

Or with "Inspect" from the GUI.
