The CFD General Notation System (CGNS) provides a general, portable, and
extensible standard for the storage and retrieval of computational fluid
dynamics (CFD) analysis data. It consists of a collection of
conventions, and free and open software implementing those conventions.
It is self-descriptive, machine-independent, well-documented, and
administered by an international steering committee. It is also an
American Institute of Aeronautics and Astronautics (AIAA) Recommended
Practice.
The system consists of two parts: (1) a standard format for recording
the data, and (2) software that reads, writes, and modifies data in that
format. The format is a conceptual entity established by the
documentation; the software is a physical product supplied to enable
developers to access and produce data recorded in that format.
