Hello guys
I am an amateur in Fluent software & I need your help!! I'm working on a CFD project by Fluent.It's very basic and simple but it's not converged That is a dry cooling tower and it's surrounding that I built them by Gambit.In that we have wind in x direct.I iterated it by a very big number but it,s not converged.also I changed solution initialization but it wasn't effective. Please help me what I have to do!!!! Thanks a lot |

Are you running LES?
Steady or unsteady? I assume that the model doesn't diverge. Which equation doesn't converge? |

Thanks for your attention
As I said, I'm an amateur and I didn't understand What you mean by LES!! Large Eddy Simulation?? I used segregated solver and steady! No one doesn't converge. What's your opinion about Coupled implicit and Unsteady??while speed of wind isn't more than 10 m/s. Is it better to use unsteady for this????? Thanks a lot |

What is your grid resolution?
You should also check usteady |
