Hi!  
I am trying to create a nested domain with DOMAINcfg.  
I want to use bathymetry field from my file _1\_bathy\_meter.nc_  
So I set `nn_bathy = 1` in _1\_namelist\_cfg_  
But it seems that DOMAINcfg ignores _1\_bathy\_meter.nc_ and creates bathymetry field of it own. Even when _1\_bathy\_meter.nc_ is not in DOMAINcfg folder _make\_domain\_cfg.exe_  
still runs successfully and creates _1\_domain\_cfg.nc_

How can I use bathymetry field from _1\_bathy\_meter.nc_ in _1\_domain\_cfg.nc_?

That’s weird. Have you checked what’s going on in your `1_ocean.output` file ?

I attached my _1\_ocean.output_ file.  
There are no error messages. I checked that `nn_bathy = 1`

Also, I looked at `bathy_metry` field in _1\_domain\_cfg.nc_  
It seems that it is interpolated from _bathy\_meter.nc_ using nearest neighbor interpolation.
