Jérôme Duriez posted a new comment:
Also, you may note that the aforementioned paper [1] used in fact
"JCFpm" model (see [*] and related classes) to describe particles
interactions (rather than CohFrictMat).

As a particular feature, this JCFpm model uses the very initial particle
distance as the force free distance (corresponding to unp in CohFrictMat
model)

If you're sticking for a while with the CohFrictMat model, note also
YADE graphical user interface offers a sub-step option (just check the
corresponding box) that may allow you to check if the distant
interaction exists at some point within a time step (before being
possibly immediately erased by the contact law in the same time step, as
explained by Bruno in #7)
