The numerical scheme also exhibits conservation of total energy to within time-truncation error.
The conservation of total energy and toroidal angular momentum are analyzed by both techniques and the results are presented.
Sample calculations have yielded excellent results, including conservation of total energy in Lagrangian steps, symmetry preservation, and correct steady-state behavior.
The scheme guarantees the exact mass conservation for each component and the exact conservation of total momentum and energy in the whole particle system.
Conservation of total angular momentum does not follow immediately from Newton's laws but demands the additional assumption that any pair of forces, action and reaction, are not only equal and opposite but act along the same line.
For staggered spatial variables it is shown how the momentum equation and the specific internal energy equation can be derived from each other in a simple and generic manner by use of the conservation of total energy.

According to the formulation, the most probable dynamical trajectory connecting the initial and final atomic configurations, is determined through minimizing an appropriate object function that is derived from the classical action by imposing dynamical conditions as required as the conservations of total energy.
In a more general method, the approximated forces will deviate from the ideal F a b + F b a = 0 by an amount comparable to their actual force errors and the non-conservation of total momentum is somewhat indicative of the accumulated effect of the force errors (see also Appendix B.3).
Despite of the different spectral truncations in different layers, round-off conservation of the total mass and total angular momentum of the whole domain can be maintained, and were confirmed numerically.
To study this mechanism we formulate the conservation equations of total hydrogen, oxygen, chloride and decane.
In the case of small atomic aggregates, for which it is not proper to consider a three-dimensional structure, we set μ(V) = 0 and assimilate them to cylinders one layer high, and perimeter determined by imposing conservation of the total atomic volume (sum of the atomic volumes of the atoms composing the 2D aggregate).
