create fluid domain with wing

[Rios]

Hello, everyone.

I am new to the forum and write for the first time. I've been looking in previous discussions but I haven't found anything that can help me. I hope I checked well. If I didn't apologize in advance.

I present to you my problem regarding the use of catia v5.

I have the stp design of a wing that I have to analyze with star ccm+.
to do this I must extrapolate the outer surface of the wing and create, on a parallelepiped represent the fluid domain, the hollow form of such wing.

Starting from the overall design and the "generative shape design" menu with the "extreme" command, I managed to isolate the outer surfaces of the various components.
I closed all the holes due to the rivets with the "fill" command and connected the surfaces of the various components with the "connection" command. after such operations I find the closed surface 3d.
is it possible to make it clear that it is a unique surface and not a set of surfaces?

How can I continue in my work to create the slave on the parallelepipedo?

Thank you.

I think what you want to do, if I don't understand badly and vice versa I apologize, is a negative mold of the wing. for this there should be an ad hoc module for cat prints or maybe in the cad3d molds section you can find information.

maybe a solution on part design could be:

1) get the full wing closed
2) create a parallelepiped that contains it
3) create a solid as a boolean operation between the previous two.
4) create an appropriate cutting plan.

you should enter wireframe and surface and design create a unique surface of the aerodynamic contour by combining surfaces and generating in part design workbench the parallelepiped extruding up to the interface surface
