Chareyre proposed the following answer:
Hi,
InteractionDetectionFactor and friends help creating "potential" distant
interactions.
To generate cohesive contacts for those interactions you can turn
setCohesionNow=True in the Ip2 functor. Else the potential interactions
are initially cohesionless, then erased in the same iteration if the
particles are not in contact.
Note that such cohesive interactions will not be force-free after
creation. Most likely they will have very large tensile forces. You can
change this by updating i.phys.unp after creation ( i.phys.unp =
i.phys.penetrationDepth).

Regards
Bruno
