This diagram illustrates the hierarchical structure of a typical CGNS
file for a structured grid.
Just below the root node of the ADF file are the following two nodes.
- CGNSLibraryVersion_t, with the data "version number".
- CGNSBase_t, with the data "CellDimension &
PhysicalDimension".
At the next level, below the CGNSBase_t node, are the following
nodes.
- ConvergenceHistory_t, with the data "number of iterations".
Below the ConvergenceHistory_t node are multiple
DataArray_t child nodes with the data "info".
- Multiple Zone_t nodes, with the data "VertexSize,
CellSize, & VertexSizeBoundary".
Below a Zone_t node are several child nodes, described
later.
- DataClass_t, with the data "type".
- ReferenceState_t.
Below the ReferenceState_t node are multiple
DataArray_t child nodes with the data "ref info".
As noted, below a Zone_t node are several child nodes.
- GridCoordinates_t.
Below the GridCoordinates_t node are multiple
DataArray_t child nodes with the data "coords".
- ZoneType_t, with the data "type".
- FlowSolution_t.
Below the FlowSolution_t node are a GridLocation_t
child node with the data "location", a Rind_t child node
with the data "rind info", and multiple DataArray_t child
nodes with the data "solution".
- ZoneBC_t.
- ZoneGridConnectivity_t.
