Why can't I change the "Hmin" of my subdomain using AGRIF?

hello everyone!

Something weird happens when I try to change the Hmin of a nested domain using AGRIF. Simply, the Hmin of the subdomains do not change, and keep almost the same Hmin of the “parent” domain. That is, the Hmin of the parent domain is 30m, so the Hmin of the subdomain is set to 29.3, even though I have defined Hmin=10m.

What causes this?

I have used “start” and “nestgui” to open the AGRIF interface and do the interpolation of the bathymetry and forcing. Likewise, I have tried calling the functions directly in the matlab terminal and still the Hmin of the subdomain does not change.

Any guidance in this case, I would appreciate it very much.

Regards,

Cesar.

Don’t forget to select the option “New Topo” in nestgui AND select the etopo2.nc file for this to work.

If you call the function directly it looks like this

nested_grid(‘./CROCO_FILES/croco_grd.nc’,‘./CROCO_FILES/croco_grd.nc.1’,30,40,5,20,3,‘/data2/matlab/CROCOv1p2p1/croco_tools/Topo/etopo2.nc’,1,0.25,4,25,0,25,4,4)
