CGNS has developed into a popular standard for the storage and exchange of CFD data in the aerospace community and is now an AIAA Recommended Practice. The use of this standard allows a compatible application or user to communicate CFD setup and information to or from other third-party CFD tools including mesh generators, solvers, and post-processors. I'll be looking into this for more details. The short course is offered during the 46th AIAA Aerospace Sciences Meeting and Exhibit in Reno, Nevada, January 7 - 10, 2008. "Effective Use of the CFD General Notation System (CGNS) for Commercial and Research Applications." Date: 5th – 6th Jan 2008. Instructors: Chris Rumsey, Thomas Hauser, Ken Alabi, Marc Poinot, and Bruce Wedan.
