11.3.3 General Purpose Grid

The general purpose (GP) grid is an unconstrained hybrid of any of the other grid types, and provides a grid description toolkit capability. It has been included in RESQML based on the recognition that industry practice in the representation of unstructured grids is still under development. It may have more utility as a research tool than as a data transfer standard. Currently no other industry standard exists to transfer such hybrid grids, so this is a unique capability.
