Question about running wrf-chem with chem_opt=203 (saprc99_mosaic_8bins_aq)

[hliu20]

Hi everyone,
I'm running wrf-chem with chem_opt=203.
I always encounter a situation where the model gets stuck during operation, and the rsl.error file does not report errors or get updated. I have tried many methods, including:

1. Modifying the time step
2. Turning off anthropogenic/biogenic emissions
3. Disabling the indirect radiation option
4. Changing the TUV scheme
5. Reinstalling WRF-Chem

However, these methods have not worked. Only by changing chem_opt to other options (204/198) can the model run normally. Has anyone successfully run chem_opt=203 (enabling indirect radiation)? If so, could you please provide a namelist? Thank you!

Here is the namelist.input file I tried running.

After running for a while, it freezes. The rsl.error log finally shows:
d01 2020-01-01_07:20:00 calling kpp_mechanism_driver
d01 2020-01-01_07:20:00 kpp_mechanism_driver: calling saprc99_mosaic_8bin_vbs2_aq_interface

Try these namelist file

Notice: Close chem_opt and auxinput5 while ./real.exe.

Hello, I also have trouble running chem_opt=203. Just want to ask if you have been running it successfully.
