Hi Chiara,

Personnally, I use the cohesionlessMomentRotationLaw and I am happy with 
it.  Depending of what you want to do you may have to make one or two 
modifications as for instance define a scale value of the plastic moment 
treshold (I dont have the code here, but if my memory is good, there is 
a plastic moment treshold defined but this latter is not scaled).
You may need also to add somewhere a line like this, depending on the 
yade version you are using (problem with quaternions):
if isnan(angle) then angle=0

But maybe Bruno will tell you that he made a lot of cleaning in the 
cohesivefritionalcontactlaw (I am not sure about the name of the law) 
and that you should use this one ;-)

Personnally, I am not very friend with code, and I like the 
cohesionlessMomentRotationLaw, because there are only few things in it 
and it is easy to follow what it is done.

Best,

Luc
