[gembud] [GEMPAK #MGD-944158]: GDVINT: [GDVINT -15] Grid size is too large.

I was able to interpolate by specifying gvcord=hybl:10/pres rather than
sgma:10/pres.  But I did not encounter the grid size problem that you're
reporting.   For that, I need to know what version of GEMPAK you're using,
and if it was built from source or install from RPM.





GDFILE   = data/gempak/model/rap/2017011216_rap130.gem
 GDOUTF   = out.grid
 GDATTIM  = first
 GVCORD   = hybl:10/pres
 GLEVEL   = 100-1000-50
 MAXGRD   = 5000
 GAREA    = 16.2810;-126.1380;55.4814;-57.3806
 VCOORD   = hght
