Hi everyone,
I am running simulations, i want to set three domains, but when i ran metgrib, there are errors: ERROR: Couldn't open file ./geo_em.d03.nc for input.
ERROR: Error in ext_pkg_open_for_write_begin.

here is my namelist.wps
&share
wrf_core = 'ARW',
max_dom = 3,
start_date = '2018-01-24_00:00:00','2018-01-24_00:00:00','2018-01-24_00:00:00',
end_date = '2018-01-25_00:00:00','2018-01-25_00:00:00','2018-01-25_00:00:00',
interval_seconds = 3600,
io_form_geogrid = 2,
/

&geogrid
parent_id = 1, 1, 2,
parent_grid_ratio = 1, 5, 5,
i_parent_start = 1, 75, 106,
j_parent_start = 1, 12, 87,
e_we = 145, 301,891,
e_sn = 100 , 381,1281,
geog_data_res = 'default','default','default',
dx = 25000,
dy = 25000,
map_proj = 'lambert',
ref_lat = 53.2,
ref_lon = -18.9,
truelat1 = 53.2,
truelat2 = 53.2,
stand_lon = -18.9,
geog_data_path = '/mnt/iusers01/fatpou01/sees01/a59246tz/Build_WRF/WPS_GEOG/'
/

&ungrib
out_format = 'WPS',
prefix = 'FILE',
/

&metgrid
fg_name = 'SFCFILE','ATMFILE',
io_form_metgrid = 2,
/

could you help me?
Thank you
Best,

The error message means that metgrid can't find the geogrid file for domain 3. Make sure that it was created when you ran geogrid.

It might be a good idea to add "opt_output_from_geogrid_path = 'the_full_path_to_geogrid_files' to the &share portion of the namelist so you know exactly where the geogrid files should be found.
