Hi,
I'm doing a simulation of steady, incompressible flow using the default values of Fluent's solver settings for turbulence and solver (SST K-Omega, coupled). In the domain of interest I have the following boundary conditions:
1- Velocity Inlet
2- Pressure Outlet
3- Pressure Inlet
4- Mass Flow Inlet
5- Mass Flow outlet (same value as point 4)

considering a good resultion mesh, I am having problems with convergence. Basically the solution doesn´t converge!

Is there something wrong with my BCs? Stability Issue?
