Hi Behzad,

I would continue by repeating what is actually the problem :-)
- interaction physics creation - at the beginning of the simulation, the
spheres are just touching, it is the matter of ronging errors if
interaction (and the physics too) are created or not
- difference of numerical and analytical results - no idea, can you check
if all parameters of O.interactions[0,1].phys are correct in Python?
