AGRIF nesting: how to set imin, imax, jmin, jmax

[sonaljit.m]

Hi,
If anyone is using the AGRIF/CROCO model, I had a small question. It is probably very simple, but I couldn't figure out. How do I set the values of imin, imax, jmin and jmax?

I have a parent grid with 2 km resolution with 224(lat)*299(lon) rho points. Within that, I am using a nested child grid at 1 km resolution with 90(lat)*122(lon) rho points. I don't know how to pick the numbers imin, imax, jmin and jmax in the AGRIF_FixedGrids.in input file. Currently it shows like this:

1
217 257 126 155 3 3 3 3
0
# number of children per parent
# imin imax jmin jmax spacerefx spacerefy timerefx timerefy
# [all coordinates are relative to each parent grid!]

When running, I am getting this error: CHECKDIMS ERROR: inconsistent size of dimension 'eta_rho': 90 (must be 89).

Can someone tell me how do I fix the imin, imax, jmin, jmax?

Thanks,
