Sorry Wagner.
As an aero CAD designer I have to step up here.
The elements of CAD that were shown so far were just a basic simulation with Ansis showing the laminar flow around the airframe and a meshing.
This in itself is the first step under Ansis in a workflow that requires over 200 steps and a considerable amount of knowledge to fully evaluate a product flight envelope and characteristics.
The second step is usually to characterize boundary layer limits and stall conditions, including limit alfa, stall speed vs mass, critical Reynolds number. Not seen.
Doing material resistance tests on an aircraft CAD product requires to have a structural assembly inputted into a DMU module for DMU composite review in a very advanced software like Catia.
What was shown on RCU was a basic surfacic part that could barely be used to trace formers.
There is absolutely no evidence that even a basic CAD analysis was conducted on any airframe so far on the aero and material resistance side.
