A coarse grid of size then stores pointers only to those blocks that intersect the narrow band of the level set.

A coarser grid for the reservoir simulation model is constructed, with perhaps two orders of magnitude fewer cells.

Therefore we can say that coarse grids are able to capture flow details efficiently.

First, determine an approximate course for each net, often by routing on a coarse grid.

With this nesting scheme a coarse grid and a fine grid simulation can be nested.

This allows regional models to resolve explicitly smaller-scale meteorological phenomena that cannot be represented on the coarser grid of a global model.

This principle is similar to interpolation between coarser and finer grids.

Restriction - downsampling the residual error to a coarser grid.

The output image is divided into a coarse grid of "buckets," each typically 16 by 16 pixels in size.

In order to enable quick and easy reproduction, all drawings were based on a coarse grid and could be executed with compass and rulers.
