On the basis of the extent of coarse-graining, the systemic CG methods are roughly divided into three major classes: (i) low coarse-graining degrees, with one or two monomers in one bead, e.g., DBI and IBI schemes and MARTINI approach; (ii) medium coarse-graining degrees, having 10–20 monomers in one bead, e.g., blob model; and (iii) high coarse-graining degrees, having the whole chain ...

Coarse-grained models are aimed at building simplified representations of complex systems that allow keeping the main chemical/physical peculiarities (such as the interplay between hydrophilic and hydrophobic effects) and performing affordable and meaningful simulations, which could not be feasible with, for example, molecular dynamics because of time and length scales limitations.

Coarse-grained materials (CGMs), including gravel, ballast, and rockfill material, exhibit a complicated stress-strain-volume change behavior, which is state dependent and influenced by considerable particle breakage even under relatively low pressure.
