    Status: Open => Answered

Jérôme Duriez proposed the following answer:
Hi,

With interactionDectionFactor = 1.2 during the whole simulation, new A-B
interactions will be created during the whole simulation as soon as dAB
< 1.2 * (RA+RB) (with dAB the distance between any pair of particles A,B
and RA, RB their radii)

With interactionDectionFactor = 1.2 in the first time step only (and = 1 afterwards), the criterion for creating new A-B interactions is  dAB < 1.2 * (RA+RB) in the first step only. (it thus concerns your initial interaction network)
Afterwards, new A-B interactions will be created as soon as dAB < RA + RB


Jérôme

PS: I guess you may replace all "<" with "<="
