Hi there,

I am running WRF v4.1.1. I am using FNL data for August 2020 (ds083.2). I am able to run real.exe for my setting of 2 domains (12 km and 4 km).
I am able to run wrf.exe for the large domain (d01), but when I switch to max_dom = 2, wrf.exe breaks down in the first time step. I tried changing the number of processors from 12 to 36, but I still get the same problem.

Here is my namelist and a couple of error log files.

Any insight would be greatly appreciated!

Thanks!

Marc

Marc,
I have a few suggestions about the namelist settings:
(1) Please reduce your time step to 60, then try again. The maximum time step that can maintain stable integration is 6 x grid interval. I am to sure where your model domains are located. So let's go a little bite conservative to 5 x grid interval'
(2) Please turn on vertical velocity damping (w_damping = 1)
(3) set radt = 12
(4) Please double check your wrfinput_d02, make sure it is reasonable.
36 processors should work fine for this case. Let me know if you still have trouble running this case.
