Hi
   I've try use auxhist to output some vars. First, I edited the Registry.EM
file like this:

state    real   u              ikjb     dyn_em      2         X     \
     i0rh05usdf=(bdy_interp:dt)       "U"                      "x-wind
component"   "m s-1"
state    real   v              ikjb     dyn_em      2         Y     \
     i0rh05usdf=(bdy_interp:dt)        "V"                     "y-wind
component"   "m s-1"
state    real   w              ikjb     dyn_em      2         Z     \
        irh05usdf=(bdy_interp:dt)  "w"                          "z-wind
component"   "m s-1"

I modified rh to rh05 and recompiled the wrf (./compile em_real)
successfully.
Then the namelist.input was edited like this:

I hope get a file like auxhist5_d4_2001-07-23_18:00:00, which contain u,v,w
but there nothing.
I mean the wrf couldn't generate any auxhist files!
I want know how to solve this problem.
Besides, I can complete wrf with the namelist.input and get
wrfout_d04_2001-07-23_18:00:00 successfully.
My system is centos5 with PGI FORTRAN 9.0 and Openmpi 1.4, the wrf version
is 3.2
Thanks!
