Version 1.0 of the Mid-Level Library was released in May 1998. ### Adoption history The official site describes CGNS as administered by an international steering committee and as an AIAA Recommended Practice. In 1999 the CGNS Steering Committee was created as a voluntary public forum, and in January 2000 it became a subcommittee of the AIAA CFD Committee on Standards. ### How it is used CGNS is used by CFD applications to exchange grids, boundary conditions, flow solutions, and related aerodynamic analysis data through a portable binary format and platform-independent APIs for C, C++, Fortran, and Fortran90. ### Why package nerds care For scientific package maintainers, CGNS is notable because it is both a file/data standard and the single public C/C++/Fortran implementation referenced by the project, with command-line utilities such as cgnscheck, cgnsconvert, cgnsdiff, and format converters. ### Timeline - 1998: Version 1.0 of the Mid-Level Library was released. - 1999: CGNS Steering Committee was created. - 2000: CGNS Steering Committee became a subcommittee of the AIAA CFD Committee on Standards. - 2001: A User's Guide to CGNS was made available. - 2011: Version 3.1 added 64-bit capability and concurrent ADF/HDF5 support. ### Related projects - The official history names NPARC, TLNS3D, CFL3D, GMAN, OVERFLOW, and Visual3 as prototype or demonstrator applications involved in CGNS development. ### Sources -
