Hi Nataliya,

It looks like you did not specify which region you want
in output file "u2" (and in this case, the default is just 
the region "0", i.e., the global statistics).
adding a line like:
> stat_region(1,1)= 1,
 (i.e., the 1rst region you defined) 
in the same namelist should do it.

I can also mentionned that the output file is either 
ASCII file (easier may be to start with) or NetCDF. 
And the netcdf file always contains all the regions, 
but only selected regions have meaningful values.
