[GEMPAK #KBG-822692]: GDCFIL error - Grid Navigation/Analysis Unknown

["Unidata GEMPAK Support" <support-gempak@xxxxxxxxxxxxxxxx>]

Evan,

I'm unable to create the same files as you (seeing a "Navigation information is 
invalid" error message), so without knowing exactly why the final file is not 
created same as the first seven, I'd ask why not simply copy day1.grd to 
day2.grd, day3.grd and so forth?  You can do with either through GDCFIL:

GDOUTF  = day2.grd                             
PROJ    =                                           
GRDAREA =                                          
KXKY    =                                         
MAXGRD  = 100                                    
CPYFIL  = day1.grd                            
ANLYSS  =       

or with a foreach in your shell script after creating the first file in GDCFIL:

set NUMS = "2 3 4 5 6 7 8"

foreach NUM ($NUMS)
  cp day1.grd day${NUM}.grd
end
