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.

The Martini model, a coarse-grained force field initially developed with biomolecular simulations in mind, has found an increasing number of applications in the field of soft materials science. The model's underlying building block principle does not pose restrictions on its application beyond biomolecular systems.

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 with less water content were subject to more particle breakage. In addition, irrespective of the initial gradings and water content, an increase in the extent of particle breakage with an increase in the compaction coefficient was observed under impact loading.

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 ].

1 Introduction. Turbulent mixing modeling and predictability rely on availability of big data generated in computational and laboratory experiments. Research challenges involve developing effective strategies for data generation, characterization, and analysis—as well as data curation, storage, mining, sharing, transfer, and visualization.
