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).
Physical data storage is accomplished via a general database manager,
either HDF (Hierarchical Data Format) or
ADF (Advanced Data Format).
The present document describes the mapping from the
Standard Interface Data Structures
(SIDS) to the file structure provided by the HDF database manager.
A similar document, the SIDS-to-ADF
File Mapping Manual, describes the mapping for the ADF database
manager.
