My project is not converged?

CFD_LES · January 20, 2011, 03:56

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
