The meeting was called to order at 7:00pm. There were 11 attendees, as listed below.
The minutes of the 17 May 2001 telecon were approved as posted on the web.
At the full CFD Committee on Standards (CoS) meeting, the committee voted to offer to serve as the US body for review for the four parts of the ISO Standard (based on CGNS). If accepted by the US governing body for the ISO process, the AIAA CFD CoS would offer voting advice to the US representative in this area.
Those present at the meeting felt that it was important that members of this committee familiar with the intent of the CGNS standard review the ISO documents before the October meeting. A deadline of 31 August was set for this review. Chris Rumsey and Bob Bush volunteered to review the documents. Steve Legensky volunteered to review the Part on Product Data Management. Those present also suggest and hope that Charlie Towne, Diane Poirier, Doug McCarthy and Steve Allmaras will be willing to review the ISO documents as well. Bob Bush will send a request for review to these individuals, collect the comments, and reply to Ray Cosner. We encourage anyone else interested in reviewing the documents to do so, sending comments to Bush or directly to Cosner.
Also at the full CFD Committee on Standards (CoS) meeting, a motion was
passed to delegate to the CGNS Sub-Committee the authority to serve as
the consensus body for defining an AIAA Recommended Practice based on
the CGNS Standard. After some discussion, the Committee members present
agreed with this proposal. Chris Rumsey moved that this committee offer
to serve as the AIAA Consensus body for defining an AIAA Recommended
Practice for storing CFD data. After a second and some discussion, it
was felt that there was insufficient attendance to formally vote on the
motion, so Bob Bush will coordinate an e-mail vote of the voting members
of the Steering Committee. Those present unanimously recommend a vote
in favor of the motion.
Bob Bush indicated that he felt that areas that would benefit from near term support included providing broader developer access to the code (to enable broader participation for development), Cartesian grid support, and the ability to support distributed memory and parallel implementations. Dave Edwards agreed to formulate a team of those interested in parallel capabilities in the API. Interested parties include: Boeing St. Louis (Fisher, Michal), Intelligent Light (Edwards), NASA Glenn (Iannetti), Stanford (Alonso), AEDC (Nelson) and Pratt & Whitney (Bush).
Armen Darian indicated that the multi-phase and spray extension still needs work, and that he would 'ping' those who have expressed interest.
Earlier in the meeting, there was also some discussion of whether
various implementations are utilizing surface data and boundary data
correctly for unstructured grid implementations. This is an issue
for post processing where the boundary surfaces must be identified to
provide functionality often desired. It was also noted that none of
the examples on the web site utilize the surface boundary condition
data structures. Dave Edwards will poll those responsible for various
implementations and try to generate an example for the web site that
contains the preferred mode of storing boundary data for unstructured
grid data sets.
The meeting was adjourned at 8:30pm.
