Interior Fan BC convergence

Hello there,
I'm working on a thermal analysis of an enclosured electric equipment that has 4 fans on it. I was testing the set up for the simulation on a simpler case. Just a 2D circular tube with a interior fan bc for inducing flow at a specific volumetric flux, but I can't make it converge.
Can anyone help me with that?

Hello Rodrigo,
I am not very well versed in the interior fan boundary condition but it seems to me that this may be a case of
1/ your flow rate being too high for the solution to be laminar as you specified it 2/ your not having set a reference pressure anywhere
When I made those changes to your file, I got convergence, see the attached file.
Best,
Jeff
