Need how many iteration times

Harry Qiu

Hi,Mr or Mrs:

I'm modeling laminar flame(methane/air).I considered laminar flow, radiation(fluid and solid), chemical reaction.Probably, because the problem is comlex(too many sub-model),no convergence is obtained even if the computer iterates for more than 10,000 times(I note that several handred of iteration time is needed in many FLUENT tuterial guides).Can you tell me that so many iteration times is correct or not?

Thank you very much! Sincerely yours, Harry.
