Hello everybody,

I'm performing (or a least trying to perform) a grid independence study.

Are the results with the highest amount of cells the most "accurate" ones? Does the shape of the cells influence this rule of thumb?

If I increase the number of cells in one direction, it is possible that I will get a aspect-ratio minimun at the point where the cells have similar dimensions with the other two directions. By refining further from this point, the aspect ratio will increase. Which one is the "accurate" solution??

I'd appreciate if someone could help me with this since I'm a bit lost when interpreting this results.

Thanks!
