Coarse graining is a computer simulation technique for reducing the number of degrees of freedom of a system. Such coarse graining provides access to longer time scales or larger effective system sizes.
Multiscale coarse-graining
Multiscale coarse-graining (MS-CG), developed by Sergei Izvekov and Gregory Voth (Refs. 1 and 2), 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.
