Granularity - Wikipedia
en.wikipedia.org/wiki/Granularity Private View
A coarse-grained description of a system regards large subcomponents. A fine-grained description regards smaller components of which the larger ones are composed. The concepts granularity, coarseness, and fineness are relative; and are used when comparing systems or descriptions of systems.

To circumvent this problem, a variety of coarse-grained (CG) models have been proposed, ranging from the generic CG models for qualitative properties predictions to more realistic chemically specific CG models for quantitative properties predictions.

What then are the major challenges of coarse-graining? In many ways the answer to this question depends on the questions one wishes to ask. For example, one common and often legitimate approach is to develop reductionist or “toy” coarse-grained (CG) models that reveal the essential physics of a given class of systems.

Coarse-grained materials are often encountered or used as backfill. It is important to understand the mechanical features of frozen coarse-grained materials when they are used in cold regions. Frozen soil is a special kind of geotechnical material, which is composed of ice inclusions, mineral particles, gaseous inclusions, and liquid water [ 2 ].

The research results showed that coarse-grained soils with better particle roundness exhibit significant shear dilation deformation; it was also found that low parent rock strength can lead to strain softening, and an increase in confining pressure suppresses shear dilation deformation.
