Description
Describe the bug
The use of adaptive time steps leads to WRF stopping before namelist's end of simulation with SUCCESS COMPLETE WRFand dt=0.
To Reproduce
Steps to reproduce the behavior:
- Use compiler and version
icc version 19.1.0.166 (gcc version 4.8.5 compatibility)
mpif90 for the Intel(R) MPI Library 2019 Update 3 for Linux*
Copyright 2003-2019, Intel Corporation.
Using built-in specs.

Thread model: posix
gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)
- To reproduce: Compile test case em_b_wave and use namelist options (add to existing &domains section)
use_adaptive_time_step = .true.,
target_cfl = 1.2, 1.2, 1.2,
max_step_increase_pct = 5, 51, 51,
starting_time_step = 600,
max_time_step = 600,
min_time_step = 100,
step_to_output_time = .false.,
- Output is
Timing for main (dt=600.00): time 0001-01-01_02:50:00 on domain 1: 0.16676 elapsed seconds
Timing for main (dt=600.00): time 0001-01-01_03:00:00 on domain 1: 0.16646 elapsed seconds
Timing for main (dt= 0.00): time 0001-01-01_03:00:00 on domain 1: 0.16646 elapsed seconds
d01 0001-01-01_03:00:00 wrf: SUCCESS COMPLETE WRF
Also for other test cases, the simulation terminates after 3 hours, e.g. em_quarter_ss if you put more than 3 hours as simulation time.
Expected behavior
WRF should run until end_hour is reached (5 days for test/em_b_wave).
Screenshots
If applicable, add screenshots to help explain your problem.
Attachments
If applicable, attach supporting files: namelist.input, rsl.* files, etc.
Additional context
Add any other context about the problem here, such as:
- This should be fixed by a bug fix in WRF4.3 as documented in the updates, right?
- Tested in WRF4.3 and WRF4.2.2
