Klaus Thoeni proposed the following answer:
Hi Klaus,

if you have defined two materials with two different friction angles
yade will take the minimum value of the two materials in contact, i.e.
clumpmatfrict=35, chutematfrict=30 -> clump-clump=35, clump-chute=30.
This should apply to all contact laws and works fine if the friction
angle of the clump material is bigger than the one for the chute
material. If this is not the case some contact laws offer the
possibility to define MatchMaker which means you can define the friction
angle in the IP2 functor on the basis of the two materials in contact.
Please have a look here [1] epecially #13 onwards.

HTH
Klaus
