I’m sorry, it’s the meshing that comes with the Analysis System “Fuid Flow (Fluent)”. I used Physics Preference: CFD, and Solver Preference: Fluent in the mesh stage.

Bottom level is indeed -5.6 and the free surface is at 0. There are also 5.6 m of air above the free surface and the top of the domain.

Here’s the output for define -> b-c -> o-c-w-s
