kcd96 is on a distinguished road
Hello dear friends,

I'm doing a vehicle simulation in Fluent 19.2. I put all of inputs and doing hybrid initialization then starting the calculations and my drag coefficient, drag force etc. graphs being up and down always change with the iteration values. When the calculation done the value which gives me last unit of the iteration. For example if I do 500 iteration, results give me 500th. values and I can not believe that results because it depends with the among of iteration how many iteration I entered. So if the graphs converge correctly I can believe the solution values. Please help If you have any idea about that problem.

Editional Info: The X coordinate values are expected values, the problem is only with none converging.
