Hi Ferenc,

sorry for late answer. Depending on exact meaning of "between clumps" (I
assume interactions only between clumps, could be also between clumps and
standalone particles), you can try:

def isInteractionBetweenClumps(interaction):
   b1,b2 = O.bodies[interaction.id1], O.bodies[interaction.id2]
   if not ( b1.isClumpMember and b2.isClumpMamber): return False # should
be interactions between clump members
   if b1.clumpId == b2.clumpId: return False # should be interactions
between members of different clumps
   return True # otherwise the interaction is between two different clumps

cohIntrsBetweenClumps = [i for i in O.interactions if
i.phys.cohesionBroken==False and isInteractionBetweenClumps(i)]
numCohIntrsBetweenClumps = len(cohIntrsBetweenClumps)

Everything could be just one Python line, but external function is created
for more readable code

I am not very familiar with CohFrictPhys, so the condition
i.phys.cohesionBroken==False for determining cohesive interactions might be
actually different..

cheers
Jan
