The meeting was called to order at 2:00 Eastern time. There were 14 attendees, listed below.
Not mentioned at the telecon, the charter has been updated on the web to
include the current list of steering committee members.
Discussions on if CGNS should be published as an AIAA Standard are still underway. There will be a telecon on this subject between Ray Cosner (AIAA CFD Committee on Standards), Jim French (AIAA Staff) and Bob Bush (CGNS Steering Committee) on 29 May. Bob will report the results of the discussion at the meeting in Anaheim.
Dave Edwards reported on progress in preparing for the Reno conference
in January. He thinks it would be timely to have another technical
paper on the status of CGNS, and can arrange for an invitation for
the ICG session. Dave will be sending out a questionnaire to collect
data for the paper. We also discussed the idea of having a Steering
Committee and/or User's meeting. We tentatively decided to hold a
one-hour Steering Committee meeting before a publicly announced User's
The next meeting of ISO Standing Committee 4 will be June 11-15, in San Francisco. This is the group whose responsibility includes the Fluid Dynamics standard. I expect this will be a fairly low-key meeting from the Fluid Dynamics perspective - no major decisions are to be made at this one. The primary activity will be to continue the process of reviewing and updating the drafts of the standard. Since the previous meeting of this group in February, we have been receiving comments and updating the documentation. All the comments received have been minor. People in several countries have agreed to put in some time at their own expense to help us develop the standard. Those countries are: US, UK, Switzerland, Sweden, Japan, and Germany. The next meeting of Standing Committee 4 will be in October, in Fukuoka Japan. This will be a major meeting for the Fluid Dynamics standard - we hope to pass Gate 3 (Committee Draft) for all the parts of the AP 237 standard. To do this, we will have to have a draft we consider to be complete in all respects. Once we reach that stage, we will have to institute a formal process of recording and responding to all comments we receive. Our response can be 'we received your comment and we choose to ignore it' (not a bright idea) but we have to respond.
Ray also sent the updated documentation to Bob Bush for comment and
review. This information will be forwarded to Diane Poirier for
inclusion on the Web site. All members of the committee are urged to
review this documentation to ensure consistency with the intent of
making a smooth transition of CGNS to an ISO standard.
Chris Rumsey indicated that he has gotten little feedback on the draft
User's Guide. However, it has been used by some groups, and has been
helpful in providing answers and a reference for several listbot
questions that have come up.
In the mean time, all parties are encouraged to continue to work on
gaining consensus for the various extensions. We would like to get the
extensions to the point where they are well enough defined to begin
implementation and the documentation is ready for inclusion in the SIDS.
(However, we do not anticipate updating the SIDS until the extension has
David Edwards indicated that Intelligent Light has developed a CGNS
inspector for their internal development that might serve as a good
starting point for Ed Hall's activity. He was encouraged to send it
to Diane Poirier to make it available as a download from the Utilities
