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
.
