WRF-Chem real.exe running problems

[Ruixin]

Hi all,

I encountered the problem when running WRF-Chem v4.0 real.exe.
I provide the part of Chem in namelist.input and rsl.error.0000.The specific errors were:
"
STARTING WITH BACKGROUND CHEMISTRY
Subroutine input_chem_profile:
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 0x7F995601C697
#1 0x7F995601CCDE
#2 0x7F99540EF27F
#3 0x20A6C05 in __module_input_chem_data_MOD_make_chem_profile

#5 0x418CE9 in med_sidata_input_
#6 0x419DB6 in MAIN__ at real_em.f90:?
"
This error did not occurred when I close the chemistry module. If i set "chem_in_opt =1", the model would stopped since I did not have the "wrf_chem_input_d01".

I hope someone can help me, thank you.

Does, ungrib/metgrid/geogrid come back with any errors?

Hi Ruixin,

See this postL Segmentation fault with real.exe and MOZCART

You will need to either modify the code or use initial conditions from a global model (e.g., CAM-Chem).
