Hi, apologize for the delay in response. The error shown in the rsl file is:
This indicates that you're using too many processors in the Y direction. It looks like you're requesting 31 processors, which can only be broken down as 31x1 since 31 is a prime number. Perhaps try a different number that will work out more evenly in the x and y directions. If you need additional information on choosing an appropriate number of processors, take a look at this FAQ.
Code:
Ntasks in X 1, ntasks in Y 31
For domain 1, the domain size is too small for this many processors, or the decomposition aspect ratio is poor.
Minimum decomposed computational patch size, either x-dir or y-dir, is 10 grid cells.
e_we = 101, nproc_x = 1, with cell width in x-direction = 101
e_sn = 101, nproc_y = 31, with cell width in y-direction = 3
--- ERROR: Reduce the MPI rank count, or redistribute the tasks.
For domain 2, the domain size is too small for this many processors, or the decomposition aspect ratio is poor.
Minimum decomposed computational patch size, either x-dir or y-dir, is 10 grid cells.

Hi，Thanks for your suggestion. I changed it to 16 or 25 processors，it still doesn't work。
I changed to wrf4.3 to fix the problem.Thanks.Okay, can you please attach your newest rsl.error.0000 file so I can see what the error is? Thanks.
