CFD General Notation System
ISO Standard

Between 1999 and 2002, an effort was spearheaded by Boeing to establish an ISO-STEP standard for the representation, storage, and exchange of digital data in fluid dynamics based on the CGNS standard. Unfortunately, the effort had to be curtailed because of budget problems. It was subsequently decided that an existing ISO standard on finite element solid mechanics would be rewritten and submitted to include CGNS as well as an integrated engineering analysis framework. Details and status on this new effort can be found in the Meeting and Telecon Minutes.

For information purposes, some of the original documents from the earlier 1999-2002 effort are included here:

Documents:

Draft of the AP for fluid dynamics data

Application protocol: fluid dynamics data: Part_237_030731.pdf
 

Committee draft of the mesh-based computational fluid dynamics - Part 1fd -

Part 1FD defines specialized components of the standard applicable only to CFD. In the future, other 100-series parts will be produced with specializations for flight test data, wind tunnel data, and other categories of fluid dynamics data. These will all be components of AP237.
