Transfer geometry
For this Tutorial the project of the Jet Engine Bracket is used.
For a Retransition to a NURBS-Geometry a non-intersected optimisation result is needed. Therefore, the Smooth-Geometry from the Post Processing can be transferred to the model tree. The geometry of this file stays always inside the Design Spaces limits except of the Interface areas, they intentionally exceed the Design Space limits to enable an easy and clean Boolean Intersection.
...
To create the final NURBS-Geometry all functional surfaces and sharp edges have to be created with Boolean Operations. The best way for this is a Boolean Intersection between the retransitioned optimisation result and the Design Space of the optimisation.
Activate the Retain Original Bodies option to keep the Design Space.
...
The result is an intersected CAD-Geometry with all functional sharp edges and surfaces. At this point it is also possible to create Machining Allowances on functional surfaces if a geometry was not already created directly during the optimisation.
The finished Geometry can be used in any CAD software and for all further steps like a FE-Reanalysis with MSC Nastran.
