Dear support,
I need to produce a WRF simulation at very hight horizontal resolution for a Medicane. All the programs are fine until wrf.exe. When I run wrf.exe the model exit before writing the first wrfout file.
I have the following error:

Now I tried two different configurations:
e_we = 800, 1041, 94,
e_sn = 800, 801, 91,
e_vert = 45, 45, 33,
....
dx = 2400, 600, 3333.33,
dy = 2400, 600, 3333.33,
grid_id = 1, 2, 3,
parent_id = 0, 1, 2,
i_parent_start = 1, 400, 30,
j_parent_start = 1, 150, 30,
parent_grid_ratio = 1, 4, 3,
parent_time_step_ratio = 1, 4, 3,
feedback = 1,
smooth_option = 0
With this configuration the model doesn't work (previous error). However it works fine with the following:
e_we = 800, 1021, 94,
e_sn = 800, 721, 91,
e_vert = 55, 55, 33,
....
dx = 2400, 600, 3333.33,
dy = 2400, 600, 3333.33,
grid_id = 1, 2, 3,
parent_id = 0, 1, 2,
i_parent_start = 1, 400, 30,
j_parent_start = 1, 150, 30,
parent_grid_ratio = 1, 4, 3,
parent_time_step_ratio = 1, 4, 3,
feedback = 1,
smooth_option = 0
Is there any maximum dimension in the e_we, e_sn or in the number e_we*e_sn*e_vert that I should respect? Can you give me some hints?
Thanks.
Stefano
