WRF-Chem 4.3.3 froze on first time step

[Giannis Koukoutsis]

Hello everyone,

I am an MSc student attempting to run WRF-Chem 4.3.3 with indirect effects enabled, in order to investigate the effects of cloud seeding on atmospheric processes. 

My configuration uses the Morrison 2-Moment microphysics scheme (mp_physics = 10) and RADM2/SORGAM chemistry with aqueous reactions (chem_opt = 41). I am currently testing a zero-emissions setup, so there are no auxiliary emission files in my /test/em_real directory.

The issue is that the model freezes at the first time step when running ./wrf.exe. The last lines of rsl.error.0000 are:

d01 2024-09-11_00:00:00  ----------------------------------------

d01 2024-09-11_00:00:00  W-DAMPING  BEGINS AT W-COURANT NUMBER =    1.00000000

d01 2024-09-11_00:00:00  ----------------------------------------

The files rsl.error.0000 and namelist.input are attached.

Thank you very much for your time and help,

With kind regards,

John Koukoutsis

Hello John

we only can help with questions related to the by us developed suite
of MOZART chemistry options and related preprocessing tools. The
option you are using is also not implemented through KPP and possibly
has not been updated in a very long time. I suggest trying one of the
KPP options.

Hi All, 

Maybe you can add the following settings in the namelist .

auxinput5_inname = "wrfchemi_d<domain>_<date>",
auxinput5_interval_m = 60, 60, 60, 60,
io_form_auxinput5 = 2,
frames_per_auxinput5 = 1,1,1,1, 

auxinput6_interval_h     = 24,
auxinput6_inname         = 'wrfbiochemi_d<domain>', 
io_form_auxinput6        = 2,

Kind regards,

Aura
