[Wrf-users] Nesting, Intermediate domain & JMAX value

[Remi Montroty]

Dear all,

I have add quite a few surprises trying to nest in version 3.3.0, core nmm.

I am using a main grid of nx=238, nj=302, and a internal grid of nx=355 
& ny=697.
Those last two values seemed to match with the rule of each value 
needing to be equal to 1 + n* 3 (the fixed parent_ratio in nmm core).

Now when I get to the model run itself (wrf, after real_nmm.exe) I get 
the following error (cf First Log). *"NESTED DOMAIN: JMAX IS EVEN, 
INCREASE e_sn IN THE namelist.input BY 1" which seems to match with *

dyn_nmm/NMM_NEST_UTILS1.F 46  <http://12characters.net/wrfbrowser/html_code/dyn_nmm/NMM_NEST_UTILS1.F.html#46>

If I do increase JMAX by 1 (ie 698), it crashes wrf.exe when trying to 
run find_ijstart_level ... (cf Second Log)

Any clue? And what is this intermediate domain in First Log?

Does anyone have an example of a set of functioning namelists for a 
nested run in WRF_v3.3.0?

Thanks !

Remi
