Greetings everyone. I'd like some help with a problem i'm facing while running wrf.exe. I'll attach my namelist, rsl.error and rsl.out files, since i'm not even able to track down the problem.

Thanks in advance

Hi,
Can you check all of your rsl files to see if you have any CFL errors in them? You can issue the command:

grep cfl rsl*

If any show up, try decreasing your time step to something more like 4xDX.

There are a couple other things that could be causing issues.
1. Domains 3 and 4 are too small. No domain should ever be smaller than 100x100 grid points (e_we X e_sn).
2. Because your domains are small, you probably don't need to use 60 vertical levels. Try to decrease this back to the default value of 45 for each domain.

Take a look at this page that provides best practices for setting up your domain.

Hello again, thanks for the response.
I rerun the model following such instructions, but now it stops with
