I am a quite new ICEM CFD user and I am trying to get a C-O grid around a complete configuration for a lifting vehicle.

I am having lots of issues about the mesh quality, skeweness and determinant, and I think it's related to the underlying geometry because starting from a quite regular geometry made by kp and lines, I have created the surfaces via CATIA V5 and then I imported the CAD in ICEM.

After importing, a lot of little surfaces appear in ICEM and after topology builiding there are some little problems such as little holes, lines not connected and things like that.

Sb know a clever strategy to avoid this kind of issues?
