11.15 General Purpose (GP) Grid Representation

The general purpose grid representation (Figure 11.15-1) is supplied as a research tool for unstructured grids. It consists of all the grid objects described elsewhere in the schema, combined in a general way. It supports block-centered, explicit geometry, implicit geometry, and higher order grid geometries. Because the general purpose grid allows objects to be mixed in arbitrary combinations, patch topology must be defined for each of the component grid types.
