I have problem in which I chose to take residual to be continuity 1.0e-06 x-veloc 1.0e-06 y-veloc 1.0e-06. But after running for more than 3000 iteration my solution is not converged. although my residual value for x and y velocity is leass than 1.0e-06. I want to know what should be the next step for me. Please help

Firstly, I would suggest that you post on the specific Fluent forum, as you may get code specific help there. However, if I understand your question although I am not sure I do, it is not wise to monitor convergence based just on the level of your residual, you should check other parameters in your solution. You have not really given enough information for anybody to be more specific, I would suggest doing so in the Fluent forum.
