Error in running wrf.exe

[naveenkrishnan1992]

Dear sir/madam,
I tried to run a simulation on the nested domain. I am using ERA-5 as input data for initialization. Till real.exe, I didn't encounter any issues. While running wrf.exe, even I didn't find the error. I kindly request you to see the input and boundary conditions and suggest me a way to resolve this issue. Herewith I have attached the rsl.error, rsl.out, namelist.input for your kind perusal.
Thank you

Evening,

Since the moderators are most likely on holiday still I will try to give some ideas.

Looking at this website (granted it is a wiki page so take it for what it is)

WRFextras - Wikicima

wiki.cima.fcen.uba.ar

Looks like you are missing some inputs in your namelist file for WRF and most likely WPS (since you didn't attach it I am assuming)

Take a look at the link and see if that solves the issue.

Hi,

I take a look at your rsl files and namelist.input. A few issues here:

(1) in your namelist.input, I could see that mp_physics = 4, 4, 4, but rsl.error.0000 indicates that :
"The microphysics option does not exist: mp_physics = -1". Please confirm that the namelist file is the one used to run this case.

(2) some options are not consistent in your namelist.input. You set
io_form_auxinput4 = 2,
auxinput4_inname = "wrflowinp_d<domain>"
auxinput4_interval = 360, 360, 360,
but you set
sst_update = 0. Please either delete the above three options, or change sst_update = 1

(3) The following options are not correct:
sf_urban_physics = 0, 0, 1,
sf_lake_physics = 0, 0, 1,

Note that physics options must be the same for all domains.

Dear sir,
Thanks for the response.
I have modified the namelist.input file. Now, I am getting other error as "Program received signal SIGSEGV: Segmentation fault - invalid memory reference". Herewith I have attached the rsl.error.0000 file and namelist.input for your perusal. I kindly request you to look into it and let me know if I need to make any changes.
Thank you

Are you able to run this case over a single domain i.e., max_dom =1 ? Please try and let me know whether ti works. if it works, it indicates that your input data is fine.

Then you can try to run a nested case. In your namelist.input, please set
input_from_file = .true., .true.,

Also, note that some options need ybe specified for all domains, including diff_opt, km_opt.

Sorry for late reply, I have modified the e_we and e_sn values. Now it is working fine.

Thanks for the update. I am glad it works!
