IGES - Surfaces from Hypermesh to ANSYS Workbench

Hi,

I have a complex geometry that I cleaned on Hypermesh: I have Suppressed edges and no more Free and Non-manifold edges, but Shared edges to define several surfaces.

I exported those 6 new surfaces into an IGES file in order to import them in ANSYS Workbench 15 for meshing and further analysis.

The problem is, once the file is imported in Workbench, I have almost 600 different bodies and visually only a line (which reveals to be a plane surface when I zoom-in a lot...), in other words, I do not recognize my geometry and this is obviously exploitable.

I think my Suppressed edges may alter something ...

Thank you in advance for your advices.
