real.exe not running

[mhafsah]

When I run real.exe, it gives me
starting wrf task 0 of 1
then it stops. the rsl.out and rsl.error pasted here. namelist.input and namelist.wps attached.

rsl.out:
-------------- FATAL CALLED ---------------

Your namelist.wps and namelist.input are not consistent. In WPS< you have the options below:

i_parent_start    =   1, 115,   170,
 j_parent_start    =   1, 100,   230,
 e_we              =  400,  598,  670,
 e_sn              =  200,  526,  718,
 geog_data_res     = '5m','2m','3s',
 dx = 18000,
 dy = 18000,

In your namelist.input, you set

e_we                                = 196,    466,
e_sn                                = 122,    259,
dx                                  = 6000, 2000,,

Please modify these options.

Sorry.. attached the wrong file. I used this file (attached here) for this run. if I do ./real.exe it stops as I mentioned in the first message.

Please remove the domain decompositions from namelist.input files:
nproc_x = 8,
nproc_y = 8,

If there are not any other inconsistencies, it should fix the issue.

From another forum post:
"It is recommended to turn off nproc_x and nproc_y because WRF will automatically decompose the domain.
If you want to manually decompose, then nproc_x * nproc_y must be equal to the total number of processors you use to run the case."
