I have the trouble with inconsistence of data input from namelist.input and input data. BUT when I changed my namelist.input, it still gets the same error. Then I did an experiment that I deleted the dx and dy value in my namelist.input, it still gets the same bad results. I wonder if this bug is connected with my previous run?
For desciption of this run, it's a LES run, I want to run ndown.exe with a coarser domain(dx=1350) and d01(dx=450) in this namelist...

Is this a nesting run with three domains? Please send me your namelist.wps to take a look. Also, please let me know what data you used to drive the model. Specifically, please save the output of the command ncdump -h met_em.d01 and send it to me. Thanks.
 
Hi thanks for your reply. This run contains 6 domains with nested condition. And I have run real.exe and wrf.exe the first 3 domains already, then I wish to run the d04-d06 as what I wrote in namelist.input as d01-d03 for real.exe, and do one-way ndown.exe and wrf.exe for each domain.
Someone says it may help by use ./clean but I don't really know if it has some risks on it.

By changing all the variable I can imagine in &domain, I found that when I change time_step from 10/9 to 1, it successfully runs. So then maybe there's something wrong with the 10/9 itself... And if I try 1.11111 or 1.1, it goes wrong, and the rsl.error are like the same. That's strange. I still want to know how can I do a time_step like 10/9 there.
 
I don't think the settings are correct in your case.
(1) namelist.wps indicates you run a 6-domain nesting case, but namelist.input shows this is a 3-domain nesting run
(2) in namelist,wps, you have the grid numbers
e_we = 91, 91, 91, 91, 91, 100,
e_sn = 82, 82, 82, 82, 82, 100,
but in namelist.input, your grid numbers are
e_we = 91, 91, 100,
e_sn = 82, 82, 100,
Note that grid numbers in D03 are wrong.
(3) time step should be six times of the grid interval of the outermost domain. In your case, it should be 72.
