The following is a list of CGNS data structures, with links to the relevant sections in the various manuals. In general, the SIDS, File Mapping, and Mid-Level Library documents are organized in such a way that choosing the link destination for a particular data structure is fairly straightforward. In the User's Guide, however, a particular data structure may be discussed in various places, and the link generally connects to the first relevant location in the document.
It should be noted that although either ADF or HDF5 may be used as the
underlying database manager, the detailed CGNS node descriptions are
essentially the same for both, and the "File Mapping" links connect to
the SIDS File Mapping Manual.
