Re: SALOME mesh overlapping

Hi guys!
I'm a new user so I hope I'm posting it right.
I'm trying to create a mesh for a flow around turbin blades to export in OpenFOAM, but I'm expiriencing some problems. I created the geometry by extruding the bottom surface. If I mesh it with no boundary layers I have no problem , but when I add the hypothesis it doesn't work (hypothesis are on the top and botton surfaces, on the central blade and on the two lateral blades). I guess it's because the little triangles that create at the bottom and at the top of the rear-left surface(the blue one).

Sometimes the surfaces don't overlap, and when I create the mesh in OpenFOAM what I get is that that surface is recognised as "faceZone".

Does someone of you know how i can fix it?
Unfortunately I can't share the python script.
