Hello all, 

I 'm a new user of Yade and I would like to perform simulations on the triaxial test of cemented sand, i,e. the grains have a specific cohesion with each other. I had gone through the example scripts (triax-tutorial. test/triax-cohesive), but I am not sure how I could specify the cohesion(normal and shear, maybe the in the CohFrictMat material properties?) 
between the grains based on a normal distribution in  the Cohesive Frictional contact law. 
I am also looking at the Jointed Cohesive Frictional model as  I could specify the bond strength between the grains. The end goal is to see the behaviour of sand with different distribution of cohesive strength between the grains, therefore I would like to have your advise on which contact model would suit the purpose best.

Thank you very much
