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.

Then, a state-dependent bounding surface model for coarse-grained materials has been proposed, highlighting the effect of initial GSD. The high accuracy of this model is evidenced by a good agreement between the modelling results and the experimental counterparts under drained and undrained conditions.

The growth of TiO 2 and ZnO thin films is studied by means of coarse-grained kinetic Monte Carlo simulations under conditions typically encountered in plasma-enhanced chemical vapor deposition experiments. The basis of our approach is known to work well to simulate the growth of amorphous materials using cubic grids and is extended here to reproduce not only the morphological characteristics ...

Coarse-grained systems consist of fewer, larger components than fine-grained systems; a coarse-grained description of a system regards large subcomponents while a fine-grained description regards smaller components of which the larger ones are composed. answered Sep 22, 2010 at 6:39.
