This chart shows the CGNS file nodes related to the storage of structured grid coordinate data. At the top is the root node, and immediately below that are the CGNSLibraryVersion_t and CGNSBase_t nodes, described earlier.

Below the CGNSBase_t node is a Zone_t node named Zone 1, containing the data values (idim,jdim,kdim), (idim-1,jdim-1,kdim-1), (0,0,0).

Below the Zone_t node are a ZoneType_t node named ZoneType, containing the data value "Structured", and a GridCoordinates_t node named GridCoordinates, containing the data value MT.

Below the GridCoordinates_t node are DataArray_t nodes containing the grid coordinates. Only one of these DataArray_t nodes is shown, named CoordinateX, containing all the x grid coordinates.
