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?
