Crash in HALO_EM_PHYS_HCW_inline.inc after 2 days in nested idealized tropical cyclone case (WRF v4.5)

[babyasleep]

Hi all,

I am running an idealized tropical cyclone simulation using WRF v4.5, with three nested domains. The model runs fine for about 2 simulated days, but then it crashes with an error related to the file HALO_EM_PHYS_HCW_inline.inc.
This module seems to be associated with halo region processing, where WRF handles data exchange at domain boundaries for physical processes.
I have double-checked that the tropical cyclone remains well-centered in all three domains throughout the simulation. The same experiment, when run without another nesting setting, completes successfully.

Any suggestions, similar experiences, or advice would be greatly appreciated!
I’ve attached the namelist.input files for both the successful and unsuccessful runs for reference.

Below is part of the log output leading to the crash:

d03 0001-01-02_20:23:13+01/03 calling inc/HALO_EM_PHYS_HCW_inline.inc

I am using the "PBS -l select=4:ncpus=100:mpiprocs=100mpthreads=1" to submit the case.
