[lammps-users] Comparison with LAMMPS

Dear LAMMPS users,

I am trying to check the accuracy of my code by comparing the kinetic energy (translational and rotational) values obtained from LAMMPS.
I am employing the same set of initial conditions and geometrical parameters for both codes (LAMMPS and mine). Also, I am running both codes on the same machine.
The KE values matches upto few time steps and after that both code’s KE values starts deviating marginally.

Is it because of the precision issue or something else?

Please help me in this regard.
