Recommendations for CATIA geometry watertight checks

[Cami11]

Greetings,

I am very new to CATIA. I am using the V5 version to produce aircraft surface geometries for CFD.

What should I do to check my CAD geometry is watertight and clean before saving an igs file and importing to CFD software?

Many thanks

Not a lot of information to go by. Have you modeled it as a surface or a solid?
If you modeled it as a solid, you wouldn't need to ask this question (and thus this could be the answer to your question).
If you modeled it as a surface or multiple surfaces, have you joined the surfaces and how did you join them?

It's been too long since I used CATIA to offer specific advice about the software.

I thought there was a CATIA app to show "cracks" or discontinuities ?
