This chart shows the organization within ISO of the existing Fluid Dynamics Standard, with the proposed additions.
At the top are the following four areas.
Below AP2xx is the new area "Part 1xx, CFD Models". Below that are the following.
Finally, at the bottom is "Part 21, Clear-Text Encoding". This already exists, but needs to be extended to include binary data.
Each of the new parts must be carried individually through the approval process. The lower-level parts will lead the way.
