Gap setting for SolidWorks Simulation“Contact” interactions

In SolidWorks Simulation, for the “Contact” interaction, my intent is to disallow to adjacent parts from passing through each other (but allow them to freely move apart) [I know this is super common].  I am getting confused, however, with the “gap range” and “stabilize the area if the gap is…” options.  I’m inclined to dial these into the gaps that I have, but is this an error?  IOW, should I go with the much larger defaults of the solver (10%, 1%)?  Also, does one need to be the larger than the other?  thanks
