This diagram illustrates an example ADF file hierarchy containing a CGNS database, but without any internal detail of the individual nodes.

At the top is the ADF Root Node. Just below the ADF root node is a CGNSLibraryVersion_t node, a CGNSBase_t node named CGNSBase1, and possibly additional CGNSBase_t nodes.

The CGNSBase1 node has as children a ReferenceState_t node named ReferenceState, Zone_t nodes named Zone1 and Zone2, and possibly additional nodes.

Below the Zone1 node are the following nodes.
