Hi Gianmaria,
this should be possible. Have a look at verification/exp4, where there
are 4 open boundaries and a net flux.
I am only guessing, but you may have a problem with an initial shock.
Either ramp up your net flux or start from a circulation that is a
little more consistent with your boundary conditions,eg. uVel = const =
uVel(on open boundary).
