− | The program below demonstrates an attempt to set the initial temperature in a regular way, in order to answer the question: ''Isn't there some way to choose the initial conditions that makes all of the averaging unnecessary?''

− | | |
− | The idea is to set the initial velocities randomly, but then the displacements are chosen in a way that the total energy (sum of kinetic and potential energies) associated with particles is a regular (not random) function of the particle number. The simulation below shows evolution of the spatial profiles of the total, kinetic and potential energies.
