Euler-Lagrangian dynamics to the physical interpretation with granular constraints for MD simulations

TL;DR

This paper uses Euler-Lagrangian dynamics to interpret particle interactions with granular constraints, clarifying non-conservative forces and improving the understanding of system descriptions in molecular dynamics simulations.

Contribution

It introduces a novel interpretation of particle interactions with granular constraints using Euler-Lagrangian dynamics, enhancing the physical understanding in MD simulations.

Findings

Interaction forces are non-conservative about the center of mass frame

Clarifies the physical nature of granular constraints in MD

Improves system description for molecular dynamics simulations

Abstract

In this article, Euler-Lagrangian dynamics explain that the two particle interaction has non-conservative forces about the frame of the center of mass. This interpretation clarifies the underlying interaction and the system descriptions become advantages for MD simulations.
