Hello,

> So, I have two questions.

please read [1], point 5 ("Do not merge different questions in one single 
post").
Here it seems as one problem, just have it in mind.

Depending on specific definitions of "the motion between particles", "being 
solved", "contact motion between particles" etc., it may be:
- applying O.cell.velGrad
- something in O.engines:
- NewtonIntegrator updates positions of particles based on their current 
state (position, velocity, mass) and applied force
- InsertionSortCollider identifies the (also potential) contacts
- InteractionLoop solves the "contact physics" (in broad sense)
- ...
- ...

as a reference documents, for start have a look at Introduction [2],
Formulation [3] and User's manual [4].

If you give more information, we can provide more focused sections
and/or other sources.

Cheers
Jan

Description changed to:
I am studying about DEM using "periodic-simple-shear.py"[1] as an example.
So, I have two questions.

1. Where (how many lines) in periodic-simple-shear.py is the motion
between particles solved?

2, How is the contact motion between particles solved?  Please let me
know if you have any reference documents.
