real.exe fails with windowed domain

[Derrick Salmon]

I am attempting to run WRF 4.5 with MPICH enables on an UBUNTU linux machine for a
domain covering the Hawaiian Island Chain and a 1:5 grid ratio windowed domain
cover the Island of Hawaii. Since these domains are relatively small and contain
complex geography I was advised to use microphysics parameters for the windowed
domain.

WRF and the necessary tools have been installed and their correct operation
has been verified per the test routines provided by the WRF web site.

WPS and WRF have successfully run the parent domain alone, without windowed domain
parameters, without issues. (mpirun -np 4 ./wrf.exe)

With WPS geogrid.exe, ungrib.exe and metgrid.exe have always ended succesfully
using variations of namelist.wps

real.exe runs successfully with max_dom = 1 set in both namelist
files (.wps and .input) when there are NO windowed domain parameters set -
i.e. no comma separated pairs.

With max_dom = 1, and with max_dom = 2, if windowed domain parameters
are set (in both max_dom cases) real.exe returns the following after
ending immediately:

starting wrf task 0 of 1

and after issuing: 'tail rsl.error.0000' the response is:

I fear there is something very fundamental that I am missing, so I need your help.
I have tried a wide variety of &physics settings but with the same (or with slight
variations) error message, always associated with num_land_cat = 21,21,. In
namelist.wps geo_data_res has been changed from '10m','10m', to '10m','2m', to
'default','default', without success. I have also tried moving the windowed domain's
lower edge vertically away from its parent domain's lower edge with no improvement.
Also attempts at using "CONUS' for the main domain and microphysics settings for
the windowed domain and CONUS-like settings for both domains without success.

A tar.gz file is attached containing current versions of namelist.wps, namelist.input,
a png image of the parent and windowed domains, computer hardware and disk usage and a
separate tar.gz file contianing log files.

few things i see in your namelists.

1. the outer domain D01 needs to be a minimum of 100x100 grid points as per the best practices page:

WRF namelist.wps Best Prac

2. for the namelist.input i would look at the best practices for this one as well.

WRF Namelist.input Best Prac

ALL GOOD - It works now - no problems remain!
Thanks William for reviewing my post. After more detailed reviews of my issues, much of what you suggest became clear. i was not aware of best practices suggesting that domains be at least 100 x 100 for example. I managed to correct a number of 9some rather silly) errors over the weekend and am happy t o report the whole things ran successfully this afternoon - it took 5 hours which is 1 hor short of what I had expected.
