---|---|---|
Approve Dec 2020 minutes. | @Scot Breitenfeld | post last meeting’s minutes to CGNS webpage. Approved |
cgnstalk: Replacement | @Scot Breitenfeld |
@Scot Breitenfeld or @Christopher Rumsey should investigate if the cgns archive can be translated to forum posts or made available on cgns.org, which would make it viewable to web search engines. @Christopher Rumsey bundled all CGNSTalk archives between 2000-2020 into one file, and posted them to the bottom of CGNS_docs_current/index.html |
Release all CGNS documentation at cgns.org into the public domain | @Scot Breitenfeld |
@Scot Breitenfeld will update the copyright information on the webpage. |
Proposed Data integration Points CPEX #0047 | @Mickael PHILIT | Please find attached a new CGNS proposal to extend GridLocation possibilities. Current CGNS features do not allow to store Solution data at Integration Points when using Finite Element Methods. This topic is quite important for CSM (Computational Structural Mechanics) and FSI (Fluid-Structure Interaction). Feel free to join this initiative as the CPEX is still a work in progress. Any feedback is very welcomed to improve the proposal, especially on the MLL and HDF5 mapping parts. @Scot Breitenfeldwill identify reviewers for the CPEX who will report before the next meeting, the CPEX is scheduled to be voted on at the next meeting. This effort should be coordinated with higher-order effort. Feedback from Tobias Leicht (DLR) and Berenger Berthoul (ONERA) taken into account. Very small modification listed at the end of version 2. This last version is ready for voting (without MLL API). |
high-level editing tools for the documentation page | @Marc Poinot @Christopher Rumsey | Raw html is not an ideal format to maintain documentation; the latex version seemed easier. It was mentioned to maybe go back to using latex, but the latex version is now out of date compared to the html version. Some committee members were uncertain whether the latex format was the right way to go when compared to other documentation methods (Markdown, Readthedocs, etc…). Either way, it will involve some effort to move from the HTML versions.
Update from @Marc Poinot:
|
Discussion Topic | @Vicky Moschou | It concerns the assumption of the different vendor softwares that elements that belong to the same Zone_BC must be grouped under one Elements_t node, and this is why the Zone_BC node is ignored in many cases. We are dealing with issue over and over again. As you can understand, this really hurts the portability of the file.
|
Status of Future CPEX 0044 | @Koen Hillewaert | The current focus is on finishing and implementing CPEX 45. Tabling CPEX 0044 for now. NO UPDATES |
Status of Accepted CPEX 0045 | @Koen Hillewaert | @Koen Hillewaert prototype implementation working and interfaced in in-house code. @Tobias Leicht is interested in testing it. Will be tested over the next few months via the HiFiTurb project. Introduce an API by the end of the year. WIll work with @Scot Breitenfeld to merge into develop when it is ready. NO UPDATES |
Status of Future CPEX 0046 | @Thomas Hauser | @Thomas Hauser will set-up another meeting in Sept. NO UPDATES
|
prioritization, review and attribution of JIRA bugs/issues | @Tony Garratt @David Gutzwiller | We would like to release 4.2 in the next month, we would like to be able to address for the release. All the other issues should be moved to the v4.3 release, those bugs that can be addressed in the next month can remain. Updated Kanban Board for release of v4.2 4.2 Kanban Board: https://cgnsorg.atlassian.net/secure/RapidBoard.jspa?rapidView=6&projectKey=CGNS General Kanban Board: We should consider a bug-fix only (no new features) release of CGNS to address the outstanding bugs and documentation. Platform proposals 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 Bug list: A priority of bugs to fix in next release #1 Crucial to Ansys. Although most HPC is Linux, project set-up often was done on Windows and import/export/sharing of mesh/solution done on Windows, while most runs performed on Linux clusters #2 #3
