[XIOS] How to zoom a region
 solved

Dear NEMO users,

I am trying to use XIOS-2.0 to get model output for a zoom region.

In original "domain_def.xml" there is a line ;

         <zoom_domain id="myzoom"  ibegin="10" jbegin="10" ni="5" nj="5" />

As far as I understand, I should put "myzoom" domain inside the "file_def.xml" file.

However, any combination of the above settings did not generate a zoom region output.

I would be very happy, if you could send these two files which have zooming capabilities.

Thank you very much. Murat

    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

    The current NEMO stable release is intended to work originally with XIOS1 but I guess you can find some examples for zooming with XIOS2 in the trunk.

    Anyway if you have have specific questions on XIOS, I suggest you to post a message on the support list

    Regards,
    Nicolas
