[Wrf-users] ndown for 3 domain

[Dominikus Heinzeller]

Hi Jim,

I am doing ndown runs for three domains the following way:

- run real for all three domains
- run wrf for d01 domain only (set max_dom = 1)
- run ndown for d01 and d02 (set max_dom = 2)
- delete d01 stuff from namelist.input, which makes your original d02 the new d01
- run wrf for new d01 domain only (set max_dom = 1)
- run ndown for new d01 and new d02 (i.e., original d02 and d03, set max_dom = 2)
- delete new d01 stuff from namelist.input, which makes your original d03 the new**2 d01
- run wrf for new**2 d01 domain (i.e., your innermost d03 domain)

Hope this isn’t too confusing either!

Cheers

Dom

I know that I need to run real.exe, then wrf.exe to process a coarse grid, then modify namelist.input to run real.exe for 2 domains for the 2 domain example, then run ndown. My question is, to run for 3 domains, do I run the coarse grid, do I make a 2 domain run, then run ndown, then make a 3 domain run, and run ndown again, or do I just make a 3 domain run after the coarse grid run, and then run ndown? I hope this isn’t confusing! Thanks.
