Embodiment Construction
[0039]The following describes several preferred embodiments of the present invention with reference to the accompanying drawings, so as to make its technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned herein.
[0040] In classical molecular dynamics simulations, the Coulomb force is a function of the reciprocal distance, which is The function computation is the most time-consuming part. A common approach is to decompose into two parts and Among them, the former part It is the error complement function divided by the distance r, which decays exponentially with respect to r in the real space, that is, the decay rate and O(exp(-r)) are of the same order of magnitude, so this part decays very quickly and can be truncated directly in the real space. To achieve fast calculation, find the short-range Coulomb...
