Dear Nemo users,

I found below document in the NEMO web page;

attachment:wiki:Developers/XIOSextras:newxios_functions_zooms.pdf

here, in below section of the pdf document, it is explained how to make zoom output!

Steps to add output files for a zoom area

I tried to test the suggestions; I add a line in domain_def.xml;

     <domain_group id="grid_T">
       <domain id="grid_T" long_name="grid T"/>
       <!--   My zoom: example of hand defined zoom   -->
       <domain id="myzoom" domain_ref="grid_T" >
         <zoom_domain id="myzoom"  ibegin="10" jbegin="10" ni="5" nj="5" />
       </domain>

and modified the file_def.xml as below;

           <file id="file31" name_suffix="_zoom_T" description="ocean T grid variables" >
              <field_group id="field_3h_zoomT"  domain_ref="myzoom" >
                 <field field_ref="toce" name="potemp" long_name="sea_water_potential_temperature" />
              </field_group>
           </file>

However, it did not also work and gave below error;

Field 'potemp' has both a grid and a domain/axis/scalar.
Please define either 'grid_ref' or 'domain_ref'/'axis_ref'/'scalar_ref'

I would be very happy, if you can send me a working xml files for a zoom output. (I am testing XIOS-2.0 with GYRE_XIOS configuration of nemo_v3_6_stable)

Best Regards, Murat
