CFD General Notation System
|
This document describes the structure of CGNS (CFD General Notation System) , its software, and its documentation. The Overview, which was written primarily for new and prospective users of CGNS, (1) introduces terminology, (2) identifies the elements of the system and their relationships, and (3) describes the various documents that elaborate the details. Reading the material on the purpose and general description of CGNS should help users determine whether CGNS will meet their needs. Those wanting a bit more detail should read the section describing the various elements of CGNS. For those interested only in understanding the scope and capabilities of CGNS, or for the end user unconcerned with the internal workings of the system, the Overview may prove sufficient documentation by itself.
The Overview also includes certain information that is current as of the document date but which may change with time. All information on CGNS compatible "applications" software (i.e., external programs such as grid generators, flow codes, or postprocessors) is of this type. Also subject to change is the information on the acquisition of the software and documentation, and the current status of CGNS.
