Seti is still having a problem:
Thanks Jan for kind support. I have downloaded yade from
"https://github.com/yade/trunk";

is that what you have recommended?

if yes,
1- How I can install it? 
installing package was really easy just copy/past the mentioned commend lines from "https://yade-dem.org/doc/installation.html"; however I am not sure how should I install the source codes. would you please assist me ?

2- I have found the source code of CPM on truck and I suppose I should
change below lines to add matchmaker to control the cohesion. so dose it
mean if I do changes in "  trunk/pkg/dem/ConcretePM.hpp" and save it
then run YADE it will work?
