Alexander is still having a problem:
Thank's for response Yan.

I already tried to read (Václav Šmilauer 2010) but the whole process
unclear to me yet. So i try to repeat it once again for u because i
think main steps in CohFricMat and CmpMat are the same.

So am i right in the following statements:

1) There are 2 types of contacts in Yade: cohesive and non-cohesive
(frictional).

2) Non-cohesive contacts appears every time when 2 spheres overlap each
other.

3) By default Yade creates cohesive contacts only at the beginning
(first step) of the simulation

4) At each step InsertionSortCollider and Ig2_Sphere_Sphere_ScGeom
classes defines only new contacts (interactions), previous contacts
update themselves (for example non-cohesive interaction brokes when they
became apart, cohesive interaction in CohFricMat  brokes when maximum
tensile or maximum shear force is reached etc.).

with regards Alexander
