Dear Foamers,
I'm super new with OpenFoam and I'm facing some issues (I couldn't manage to get a converged solution) in a case that I have to simulate with SRFSimpleFoam in foam-7.
The case is a rotating duct (100rpm wrt the x axis) through which water flows. It is a really simple case and I cannot understand what is wrong with it.
Because of simmetry, only a sector of 20° is meshed, with cyclic AMI used at periodicity patches. As boundary conditions I set an inlet total pressure (101325 Pa, considering that the density of water is 1000 kg/m^3, we have 101.325 M^2/s^2) and an imposed volume flow rate at outlet. I attached an image of the domain and all the text files set to run the case (in polymesh I only left boundary because of dimension limits, but if you want the mesh I can try to find a way to share it).
Do you have any idea about what is the mistake I'm doing?

Thanks in advance,
Lorenzo

Modifying the BCs the problem was more or less fixed (setting an inlet velocity field and an outlet static pressure).
