Error in running ndown

[Ravi Prakash Maurya ce23d031]

Hi,

I am trying to run finer resolution run over the himalayan region. I made my first coarse resolution run of 30 Km grid size. Now I am trying to run ndown to run on a grid resolution of 6Km. While running ndown, It stops within few minutes.

I am using following steps for running ndown.

1. made a coarse grid run.
2. made geogrid.exe, ungrib.exe and metgrid.exe for 2 domains.
3. ran real.exe for both domains.
4. generated emissions files for both domains.
5. ran real.exe with emission files
6. renamed wrfinput_d02 to wrfndi_d02
7. edited &time_control and io_form_auxinput2 and interval_seconds.

Then I gave the command for ndown. It stops with no error in rsl.error.0* files.

The rsl.out.0* ends with:

I am attaching my namelist and rsl.error.0000 and rsl.out.0000 for your perusal. I would be very thankful for any suggestions to resolve this error.

Hi  Ravi

this is more a question for the MPAS-WRF Support Forum (https://forum.mmm.ucar.edu/) but what I suggest doing first is to set debug_level = 12 (or higher) and see whether the error message you receive has more detailed information. 

I also recommend changing to phot_opt=4 (see https://www2.acom.ucar.edu/wrf-chem)
