Jan Stránský proposed the following answer:
> how can I write code for Normal Force
one option is O.forces.setPermF [2]
> how can I write code for Friction
mat = FrictMat(...,frictionAngle=0.5) # [3]
O.materials.append(mat)
> which contact law to use as I am new to this?
For start, use the "most basic" Cundall-Strack law [4].
Once you get familiar, you can add different parameters and/or use different
contact models
Cheers
