CFD General Notation System

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. CGNS is designed to facilitate the exchange of data between sites and applications, and to help stabilize the archiving of aerodynamic data.

        Release Notes: This version includes 64-bit integer capability. HDF5 is now the default file type when CGNS is built with HDF5 version 1.8 or later. Two new functions were added to more easily read and write GridLocation data for boundary conditions: cg_boco_gridlocation_read and cg_boco_gridlocation_write. Implementations of CPEX 0027 (Time-dependent Connectivities), CPEX 0030 (Zone Sub-Regions), and CPEX 0031 (General SIDS Improvements) were added, along with the alpha release of Parallel CGNS.
