WRF hangs when running an LES at 250 m

[gpriftis]

I have been trying to run a one day of simulations over the Java island. While Java has a complex terrain with mountain reach 3km height, the inner domain is over flat terrain. The wrf.exe hangs at 9 UTC no matter all the different combinations of schemes I have tried.

I am running a 3 domain simulation at 4km, 1km, and 250m. I also have 69 vertical level. I have experimented with different time steps but haven't been able to run the simulation successfully so far.

I have included the namelist and error files in the zip file attached below. Any help or guidance would be appreciated!

I don't know what the issue is, but can I ask why are you using a 4 grid ratio? It is usually recommended to use odd-numbered ratios of grid spacing (but not too large), so 3 or 5.

@gpriftis,

Can you try running this again, but with the following changes:
1) set debug_level = 0. This rarely produces any useful output and just adds a lot of junk to the rsl files, making this very large and difficult to read through.
2) Can you try running this with 144 total processors (so that the decomposition will be an even 12x12 processors)? It's not mandatory that the decomposition be squared, but since there's a significant difference between your 8 processors in one direction, and 16 in the other, I just want to eliminate the possibility that that may be causing any issues.

After that, assuming it will still fail, please package your new namelist.input file, and all of your rsl* files into a single zipped file and attach that. Thanks!

Thank you @kwerner !

The simulation failed again. I have attached the files below.
