Coarse graining is a computer simulation technique for reducing the number of degrees of freedom of a system [1]. Such coarse graining provides access to longer time scales or larger effective system sizes. This method is particularly useful when it comes to simulations of large and/or complex modes such as those encountered in studies of biological systems or synthetic polymers.[2][3]
Multiscale coarse-graining[edit]
Multiscale coarse-graining (MS-CG), developed by Sergei Izvekov and Gregory Voth [4] [5], employs a variational principle to determine an interaction potential for a coarse grained model from simulations of an atomically detailed model of the same system.
