SW Simulation tutorial: hull model does not work as described

Simulation

Hello

I'm getting a little into SW Simulation (2019) by doing the integrated tutorials.
For the hull study, I don't really understand (it's true that that's why there are trainers ;-) ): the part provided already has a median surface and the main body is removed.
In the tutorial, it says:
"The middle surface of the sheet metal part is displayed. The software automatically meshes the surface bodies with shells. To view the volume size, cancel Body-Delete in the FeatureManager design tree."

My problem(s):
- I don't know how the median surface is generated;
- When I validate the creation of the study, nothing happens (no surface creation, no meshing). I tried to start from a "normal" sheet metal model (even if the model provided is rather rotten in terms of modeling method), it doesn't change anything.

What did I miss?
Attached is the document provided.

Hello @stefbeno,

Welcome to the magical world of simulation...
In the attached document, some images to try to answer your questions.

Kind regards.

Superb, thank you very much.

Seeing the way it's presented, you get the impression that it's the software that does the conversion.
So, in fact, it's up to me each time to create the surface, it's noted.
