Excuse me, let me ask, when I ran wrf.exe the model I was running stopped at a certain time. I tried running 2 models with different resolutions and the same settings but the model stopped. Below I attach a photo of the error in rsl.error and namelist.input:

Hi,
Can you package all of your rsl* files together into a single *.tar file and attach that, as well? Thanks!
 
Hi,
In your rsl* files, there are several "cfl" errors listed. For e.g.,

Code: 
rsl.out.0005:d01 2021-04-04_00:12:00          126  points exceeded cfl=2 in domain d01 at time 2021-04-04_00:12:00 hours
rsl.out.0005:d01 2021-04-04_00:12:00  MAX AT i,j,k:          425          42          20  vert_cfl,w,d(eta)=   5.87797070       9.59663200       4.88601625E-02
rsl.out.0053:d01 2021-04-04_02:08:24          289  points exceeded cfl=2 in domain d01 at time 2021-04-04_02:08:24 hours
rsl.out.0053:d01 2021-04-04_02:08:24  MAX AT i,j,k:          429         353          26  vert_cfl,w,d(eta)=   837337.688       37919996.0       2.70687416E-02
rsl.out.0053:d01 2021-04-04_02:08:24          130  points exceeded cfl=2 in domain d01 at time 2021-04-04_02:08:24 hours
rsl.out.0053:d01 2021-04-04_02:08:24  MAX AT i,j,k:          425         353          18  vert_cfl,w,d(eta)=   673.703247                  NaN   5.00418246E-02

This is likely because your time_step is too large. time_step should be 6xDX or smaller. Reduce your time_step in the namelist to see if that gets you past the cfl errors. If not, take a look at this FAQ, which discusses how to correct these errors.
