Hello,

> As for moving the object I use PyRunner and in every time step I
change its position.

I advice you to not do that. (Tangential) Contact laws are based in Yade
on bodies velocities. With such change in position, the contact forces
will not reflect the relative displacements. Better set your object as
non-dynamic (*), and assign it a velocity that will then be constant
because of the non-dynamic feature. NewtonIntegrator engine will take
care of changing the position of this body (according to this velocity).
