Example 1. A GP grid may be used to represent a discrete fracture model by combining an IJK grid, which describes the geometry of the matrix of a reservoir, with additional discrete fault “cells” for which volumes and transport properties are provided, but with no explicit geometry. The cell indexing of such a model would be 3+1, similar to the truncated IJK grid representation, but without any of the cell truncation description.

Example 2. Because the count of elements is not constrained in a GP grid, it supports degenerate grids. For example, an IJK general purpose grid with NK=0 will be very similar to a grid 2D representation. Similarly, a triangulated mesh could be represented as an unstructured cell GP grid with a cell count of 0, but with nodes and faces.
