  According to the shock jump conditions, the total fluid's mass, momentum, and
energy should be conserved in the entire simulation box. We perform the
dynamical Monte Carlo simulations with the multiple scattering law for energy
analysis. The various energy functions of time are obtained by monitoring the
total particles' mass, momentum, and energy in the simulation box. In
conclusion, the energy analysis indicates that the smaller energy losses in the
prescribed scattering law are, the harder the energy spectrum produced is.
