What is the data of "astergdem_5s" in your namelist.wps?

Can metgrid.exe run successfully over a single domain (max_dom =1)?
Dear Ming Chen,
The name "Astergdem_5s" is given by myself. It is actually ASTER GDEM V3 (ASTER Global Digital Elevation Model V003)data. Yes, When I ran with these grib data several times before that simulation , I could run . But this time, I got that kind of error.
Yesterday, my professor told me to run the simulation with the same start date and end date for nested domain. When I set the same start date and end date for nested domain, metgrid exe could be run successfully.
But it is a little strange. Why could i run the simulation before that without setting the same time? May be the simulation time is longer than before.
Thank you very much for your time.

I am glad the case works. Yes Please make sure that you have data available for the simulation period specified in your namelsit.wps.
