Klaus Thoeni proposed the following answer:
Hi,

MatchMaker need to be defined in the Ip2 functor for each pair of
possible contacts, e.g. when you have two materials:

	...
	[Ip2_FrictMat_FrictMat_MindlinPhys(
		# define restitution coefficients between different pairs of material ids
		en=MatchMaker(matches=((matId1,matId1,.4),(matId1,matId2,1),(matId2,matId2,1)))
	)],
	...

You can avoid (Mat2,Mat2) if you are sure this will never happen, e.g.
for the wall.

The error you get tells you that there is no parameter defined for an
interaction of material id 2 with material id 2 (2,2).

What contact law are you using? Just carefully define all the matches
for all the parameters and it should be fine.

HTH,
Klaus
