[Wrf-users] Running ndown problem

[crystal_paulsen at und.nodak.edu]

Hi,

I’m trying to run ndown for a one-way nest and am getting a floating 
point error while running ndown.

For initialization of my outer domain, I used NCEP Reanalysis data.  
My domains are configured as follows:

Domain 1
220x180  at 15 km grid spacing
51 vertical levels

Domain 2
601x601 at 1 km grid spacing
51 vertical levels

For the outer domain I generate hourly output files which I use to run 
real.exe and wrf.exe for that domain.  Then renaming real_input_d02 to 
real_input_d01 and using the output file from the 1st domain I run 
real.exe for domain 2.  Then renaming wrfinput_d02 to wrfinput_d01 and 
real_input_d01 back to real_input_d02, I try to run ndown, but it 
fails with a floating point exception.

If anyone has an ideas on solving this problem it would much 
appreciated.
