Recommended Practice: The CFD General Notation System – Standard Interface Data Structures

The CFD General Notation System (CGNS) is a standard for recording and recovering computer data associated with the numerical solution of the equations of fluid dynamics. The intent is to facilitate the exchange of CFD data between sites, between applications codes, and across computing platforms, and to stabilize the archiving of CFD data. The CGNS system consists of a collection of conventions, and software implementing those conventions, for the storage and retrieval of CFD data. It 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.
