Abstract
Molecular dynamics is one of the methods used now-a-days by the scientific community to study the property of polymers. This paper presents a new method for multiscaling molecular dynamics that combines the advantages of fine-grained and coarse grained representations. The new methodology is implemented in the package Gromacs for molecular dynamics, a world-wide used software that achieves the best performance on single processors. The article presents the methodology, its implementation in the Gromacs package for molecular simulation and performance results. Keywords: polymers, molecular dynamics, Gromacs, multiscaling modeling
