What does that mean.
I have bounding epsilon and bounding k in the log file which i am trying to correct (unsuccessfully)

Hi Gabbee,

Though it posted a long time ago, I am currently facing this problem especially when trying to work with a steady state solution. Did you solve this issue? If so, How did you increase the iteration number?

Cheers,
Razon

If the Initial residuals of every variable dip below the value defined in the residualControl sub-dictionary of the fvSolutionDict the solution is considered converged.
So if your simulation converges to early you might want to decrease the residualControl value. A value in the rage of 1e-4 to 1e-6 can be considered to be converged, with the latter offering better convergeance than the former.

Hi RobertHB,
Thank you very much for your advice. It is working fine now.

Cheers,
