Question #298001 on Yade changed:
https://answers.launchpad.net/yade/+question/298001

Klaus Thoeni proposed the following answer:
Hi,

you can indeed use FrictViscoMat and the corresponding functors to do
this task. Have a closer look at [1] and you will see that the Ip2
functor supports MatchMaker where you can define kn, kRatio and
frictAngle. ks is defined by the attribute kRatio, i.e., ks=kn*kRatio.
If no MatchMaker are defined the standard implementation of Yade
(harmonic average) is used. It's that easy ;-)
