I have two questions, I think they are two questions connected to each other.

1. My aim is to study the performance of a 'hydro' foil with OpenFOAM (and later on a propeller) and I'm going to create the computational domain with Salome. I'm an absolute beginner, so I proceed step by step. I made a simple model: a parallelepiped cutted by a cylinder; then partitioned by two planes (look at the picture). I'm trying to build a hexahedral mesh but i only obtain the message 'Unexpected geometry. Wrong number of wires' or similar. Can you help me, please?

2. I tried to 'translate' in GUI language the TUI tutorial about the hex mesh for a cylindric domain (on Salome). I almost made the grade (sic!) but I have some problems about 1D discretization. I can't set a different number of segments for each 'dimension', as in the tutorial. Maybe I'm wrong with the 'side group' (are face_a and face_b the bases of the cylinder?). My parameters are

[whole object]
hypotheses: nb Segments = 1;
algo: regular_1D; quadrangle_2D; hexa_3D;

[face a, face b]
hypotheses: nb Segments 1 = na, nb;
algo: regular_1D; quadrangle_2D;

[side group]
hypotheses: nb Segments =nl;
algo: regular_1D; quadrangle_2D;
