Question #234854 on Yade changed:
https://answers.launchpad.net/yade/+question/234854

Klaus Thoeni proposed the following answer:
Hi,

some contact laws like HertzMindlin allow the use of MatchMaker, (see e.g. 
examples/spheresFactory.py). It works as well with the damping coefficient cn, 
e.g.:

cn=MatchMaker(matches=((steelId,shotsId,.4),(shotsId,shotsId,1)))
