[solved] can't manage to perform elbow tutorial

It was a couple of months I didn't work with cfdOF, and my first attempts were not successful. I then decided to go ahead with tutorials, and began with Elbow. However I didn't manage to obtain a convergence:

ah ! After a (fresh) beer, I thought to the first thing I should have tried: I tried with SnappyHexMesh, and it went fine.
