Reply To: CFD Simulation: Reverse Flow Issue at Outlet2

[jingyuliu]

a followed question:
the convergence criteria i set      continuity 1e-5; x-velocity 1e-6, y-velocity 1e-6, z-velocity 1e-6.
but in the k-epsilon stable simulation, the countinuty cannot decrease to 1e-5. It is stuck in the 1e-3. But the x, y, z velocity is already convergent. Should I decrease the convergence criteria of continuity from 1e-5 to 1e-3 to make the flow stable.
