Help needed to divide the remaining tasks:

The documentation goes into the source using Doxygen. This work uses the “doxygen” branch. Examples are given for cg_open and cg_version. The aliases used for repeated variable descriptions are in src/doxygen/doxygen.config. Need volunteers to help with translating the remaining APIs to Doxygen.

Discussion Topic

Vicky Moschou

NGON sample file, issues with cgnscheck concerning NGON

Discussion Topic

ZJ Wang

Short discussion on past AMR CPEX (0008) and whether AMR should be revisited as a feature supported CGNS. Some groups may be already using CGNS with AMR, but not known for certain. The need for AMR support in CGNS is unknown.

ISSUE CARRIED OVER:

Platform proposals
Windows is under-tested. Suggest Test C and Fortran serial and parallel on Windows 10 x64 as a bare minimum

Do we test both 32bit (legacy) and 64bit API? It's a minor point, but it would a good idea to add 32bit to at least one Linux and Windows

NEW (June 2021) We need to add Intel OneAPI compilers to the list of supported compilers (note: OneAPI C/C++ compiler is very different to existing legacy one)

Bug list: https://cgnsorg.atlassian.net/browse/CGNS-176
