To do that, you must link masses with a link with a Lmax value 
corresponding to the length of the link, for example:
link rebound mass1 mass2 10 10 0 1

The way to do that is to use some tangeantial link, simulating fluid 
resistance, you must introduce a resisting point:
mass m0 0 100 0 0
and then
link damping mass0 mass1 0 3
for the mass1
there is a damping in the msd/02_msdstring example
