Dear all,

I'm known with the method to report the grid convergence index (GCI) for three different grids, refined with a specific factor.

In my current study, it was interesting to test more grids to limit the amount of cells in the domain.

In this case I used a refinement factor of sqrt(1.5) (3-dimensional) resulting in the following grids:

name: coarser - coarse - normal - fine - finer
cells: 5,920,521 - 7,511,143 - 9,824,494 - 12,770,949 - 16,970,219

What would be a good way to report the GCI in cases with more than 3 grids (to be able to choose the appropriate grid for further analysis)?

Kind regards,
Rob
