This diagram illustrates the use of a link from one CGNS file to grid
coordinates stored in a separate CGNS file.
The diagram shows two CGNS files.
File 1, on the left, has the following CGNS base node.
- Name: FlowSolutionBase
Label: CGNSBase_t
Data: CellDimension=3, PhysicalDimension=3
The CGNS base node in File 2, on the right, is:
- Name: GridBase
Label: CGNSBase_t
Data: CellDimension=3, PhysicalDimension=3
Both files contain identical Zone_t nodes below the
CGNSBase_t node, as follows.
- Name: Zone 1
Label: Zone_t
Data: VertexSize=(21,17,9), CellSize=(20,16,8),
VertexSizeBoundary=(0,0,0)
In File 2, below the Zone_t node are the following two nodes.
- Name: GridCoordinates
Label: GridCoordinates_t
Data: MT
- Name: ZoneType
Label: ZoneType_t
Data: Structured
The grid coordinates themselves are stored in children of the
GridCoordinates_t node, not shown in detail in the figure.
In File 1, below the Zone_t node are the following two nodes.
- Name: FlowSolution
Label: FlowSolution_t
Data: MT
- Name: ZoneType
Label: ZoneType_t
Data: Structured
The flow solution itself is stored in children of the
FlowSolution_t node, not shown in detail in the figure.
In File 1, in addition to the FlowSolution_t and
ZoneType_t child nodes, the Zone_t node is linked to
the GridCoordinates_t node in File 2.
To the user, the GridCoordinates_t node in File 2 appears as
a child of the Zone_t node in File 1.
