Sedullo is on a distinguished road
I am performing a mesh indipendence study but I have some doubts, I am taking as reference value the average Nusselt number along a vertical wall, keeping fixed the Grashof number, the values that I got are the following:

Cells -> Nusselt number value

9375 -> 13.93
37500 -> 13.86
84375 -> 13.81
337500 -> 13.74

I do not have much experience with this kind of study, what are the parameteres that I have to consider to make the right choice?
