Brief Description of CGNS
The CFD General Notation System
(CGNS) 
is a set of
standards, together with software implementing those standards, for the
recording of data associated with Computational Fluid Dynamics (CFD).
The present document describes the mapping from the
Standard Interface Data Structures
(SIDS) to a file structure provided by an underlying database manager.
Physical data storage is accomplished via a general database manager,
either ADF (Advanced Data Format) or
HDF (Hierarchical Data Format).
