interactionDetectionFactor is more aimed at CREATING distant 
interactions, not for deleting them. It is not supposed to be used for 
cohesive interactions (it's been introduced for capillary interactions).
Using interactionDetectionFactor>1 just to make cohesive contacts work 
in tension would be a waste of resources.
Using interactionDetectionFactor=1 and computing geometry for real 
interactions only is the way to compute only what is needed.
