Labelized Catia V5 Surfaces and export these label into STL format

Labelized Catia V5 Surfaces and export these label into STL format

(OP)
Dear all,

First of all I want to introduce my self.
I am Pascal, French Engineer, and I use CATIA V5 and V6 in my company.
I am working on CAD-CAE link aspect.

I am interesting in sharing knowledge and bests practices into CAD and PLM Methodologies and Meshing capabilities too.
Also, if I can help, I will do it!

But for now it is me who needs help.

I am looking to extract a catia geometry and convert it into stl format.
The main issue with the stl format is that there are the nodes and their coordinates and the facets composed by their nodes.

How can I put from CATIA, an identification of a group of facet like a label or Publication, that able to identify a surface and write it into the stl format like this:

STL Format

1 0.1 0.3 0.5
2 1.0 2.0 3.0
3 0.4 0.5 0.6
Facet
1 1 2 3 Boundary_Condition_1

In order to have needed information for a CFD solver to know where to put the Boundary Conditions.

Many thanks in advance if you have some clue on it.

Best Regards

Pascal
