Hello dear friend

I'm studying on the grid convergence index, presented by Celik, et al whose their article in this case can be found in the link below:
http://www.taoxing.net/web_documents/p4enew.pdf
Now I have got some question that how can I calculate area of each cell mentioned in step 1 of this article and then do I need to calculate area of all cells? How come it is possible?
I'm So confused

Check out these papers:
Roache 1997 "Quantification of numerical uncertainty in computational fluid dynamics".
Freitas, 2002 "The issue of numerical uncertainty"

There is a clear explanation on how to compute GCI. I don't think you need to compute the area of each cell.
Cheers!
