Fail to converge

I'm running an air flow in a room simulation, but my solution does not converge, even to 10E-4. What can I do to improve convergence?

Hello.
Have monitored any other parameters such as velocity or pressure at some planes? 10e-3 continuity convergence is good enough for room simulations as there will be many recirculation areas. Check your mass balance too. Convergence is not just about achieving 10e-4 or something. Thanks and regards, Hari |

khnayanar ! I also have similar simulation of air passing through a box (30X40X50 cm3) which have re circulation areas. Convergence criteria is 10-4 but solution is not fully converged. I also done imbalance analysis. Can you comment that this convergence acceptable? (pics attached)IMG_6153.jpg
