I'm modeling the natural convection .After 6000 steps iterations,the result in the fluent is :The residual of the continuty, energy, k ,epsilon, all below 0.001,and the do-intensity below 10^-6 ,but the x-velociy，y-velociy，z-velociy are ab 0.01 there ara horizontal lines:resi.jpg,and the velocity is very small ,the result display that the max velocity is 10^-14. I monitor the temperatur of the out let ,the temperatur is steady not changed.Can I deem the result is converged？The result is right or wrong?Thank you very much!

this post helped me with the same question.. there are lots of other good posts about judging convergence and the fluent user guide even has info on it. you are already on the right track looking at the behavior of your variables of interest and not purely trusting the value of residuals

Hello:
I am on a computer simulation study about "Cyclone Separator " by ( ANSYS Fluent 14.5), but I'm having some difficulties which it as shown on photo, I need to be the lines much smother and lower than 1e-4 but I do not know how ,please help me
Thank you
