Merging surfaces issue

[Torsion]

Hi all,

I have a problem merging surfaces using Catia V5. I'm working on a race car prototype and I'm preparing surfaces to make a CFD analysis. The problem is that I cannot merge the diffuser with the rest of the bottom. I use the HEALING tool but then if I check the result with the BOUNDARY command, seems to not be joined:





Not sure what's going on, I tried to extrude the pannels to the upper face and then to heal... no success. I tried to heal before every part was created... no success.

Best Regards

The Healing (and Join) tools in CATIA V5 are used to join adjacent surfaces that share a common edge. The two diffuser surfaces cannot be joined with the other surfaces to form a single surface.

Oh they must share an edge? Didn't know it! Thanks!

Is there any tool to do what I pretend? I guess another option is to cut the bottom surface with the diffuser edge in order to create the intersection and then execute the healing/join command. I will try later.

Thanks again for your reply.

You could make solids from your surfaces, which would merge everything into a single 3D shape.

(I don't know anything about CFD analysis - does it work with solids?)

Maybe, I'll try it (I also tried intersecting difusser and the bottom surface to create an edge and doesn't work).

Do you mean making solids by "sew surface"?

Based on the previous picture, I would use the ThickSurface in the Part Design workbench
