Discussion topics
Item | Presenter | Notes |
---|---|---|
Approve 2022/10/11 minutes. | @Scot Breitenfeld | post the last meeting’s minutes to the CGNS webpage. Approved |
high-level editing tools for the documentation page | @Marc Poinot @Christopher Rumsey | Help needed to divide the remaining tasks: https://github.com/CGNS/cgns.github.io/projects/1 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. We need volunteers to help with translating the remaining APIs to Doxygen.
Still in progress. We are looking for volunteers for help.
|
Converting CGNSTalk archive to Github Discussion Posts | @Scot Breitenfeld | Hope to be completed by the next meeting. Still WIP. |
GitHub Issues | @Scot Breitenfeld | Discussion moving from Jira to GitHub issues to track code issues. Completed move to GitHub |
Added UTF-8 support | @Scot Breitenfeld | Should CGNS support UTF-8? It can be a lot of work to support in CGNS, and could have detrimental effects on performance (sometimes seen with NetCDF). |
Coupled fluid-structure standard addition | @Scot Breitenfeld | Working on a proposal to standardize fluid-structure simulations. |
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. @Vicky Moschou @Tobias Leicht @ZJ Wang to discuss progressing CPEX 0008. @Vicky Moschou @Tobias Leicht @ZJ Wang to discuss it with interested parties before the next meeting.
|
Status update on Accepted CPEX #0045 | @Koen Hillewaert | The branch CPEX45_high_order has not been updated since Feb 25, 2020. An update from @Koen Hillewaert on the status is needed. No updates. Regarding the two topics that I might want to say something on I have collected some input – feel free to use it (or not):
|
Discussion Topic | @Mickael PHILIT | Proposal to have Monitoring numerical probes description to the standard. Some groups may already use CGNS to do that, but there is a need to have a shared approach. Committee needs to review the proposal and provide feedback. Feedback was received.
@Mickael PHILIT will resend CPEX, please it review before the next meeting. @Scot Breitenfeld Will schedule discussion and vote for next meeting. |
Status update on Accepted CPEX #0047 Proposed Data integration Points | @Mickael PHILIT | Working on the new website before creating a new development branch to prevent duplicating efforts. Started prototyping with python and C and will push a branch on GitHub in the upcoming weeks. (The “C” branch is a slow work in progress) No new updates. Still in progress. |
prioritization, review and attribution of JIRA bugs/issues | @Tony Garratt @David Gutzwiller | Next release 4.4.0, Kanban:
Current status for Ansys: No issues that are urgent. We would like confirmation on the recommended build practice: autotools or cmake? Are both supported or just cmake? Autotools and CMake are both supported on Linux/OsX, CMake is preferred (i.e., is regression tested) for Windows. @Scot Breitenfeld is working on updating the Multi-dataset APIs in CGNS to use the new array-based API and is testing CGNS with the new HDF5 subfiling feature. @Scot Breitenfeld Can the APIs default to writing one dataset at a time if CGNS was not built with HDF5 1.14.0?
