hanzj is still having a problem:
dear prof.Bruno:
Thank you for your reply, and I understand what you mean mostly.sorry, I still need your help as follows:
first,I have searched for what you recommend "assign the adhesion to the different group", for example ,the question "https://answers.launchpad.net/yade/+question/257929"[1] .is that what you meant? and I would try to use it then and put my simple scripts here.
another question, if i am going to model the nano indentation process, and i would like to use PFacet to model the hollow glass sphere, just not take into account the splitting of the PFacet, it remains elastic or even plastic state. and i use a spherical indenter to indent the composite made of glass sphere and cement paste. I want to use DEM to model the nano indentation because my material tends to be a particular problem, and I am going to model the loading and unloading process and plot the diagram between the repulse force acting on the spherical intender and the indenter displacement. there are other authors use FEM to model the indentation like http://www.sciencedirect.com/science/article/pii/S0040609016302966[2], are there any other authors using DEM method or even YADE to do that? how to calculate the repulse force acting on the indenter? The bonds between the sphere and cement paste might be week enough to break down first and i have to calibrate the adhesion between two different materials, right? any ideas or recommendations?
If I have any logical problem and state that not correct, could you please let me know, thank you.

looking forwards to your reply.

best regards
hanzj
