CFD General Notation System
As part of its role as a sub-committee of the AIAA CFD Committee on Standards , the CGNS Steering Committee is involved in the development of the AIAA Recommended Practice for recording and recovering computer data associated with the numerical solution of the equations of fluid dynamics. The Recommended Practice consists of the CGNS Standard Interface Data Structures (SIDS) document, reformatted to conform to AIAA's requirements.
The current AIAA Recommended Practice (corresponding to CGNS Version 2.4) is available at the AIAA Online Store , and as a PDF file (1.01M, 200 pages; copyright AIAA, made available here by permission) at the CGNS Documentation web site. The PDF file may be viewed and/or printed using a variety of freely available software packages, including Acrobat Reader , GhostScript , and xpdf .
