Good morning,
The following namelist.input works when step_to_output_time = .false. However, if I change it to true, the simulation unfortunately doesn't work. Do you know why this might be happening?

Hello, I use WRF 4.3.3.
when I set use step_to_output_time = .true, it's as if success complete ends at the first time step, when I set it to false, the simulation continues normally

Can you upload your namelist.input for me to take a look?

Please confirm that the only change between your two tests is step_to_output_time = .false. or .true.

Would you please try WRFV4.7.1?
 
I try with WRFV4.7.1, and the results are the same. step_to_output_time = .false. works but step_to_output_time = .true, it's as if success complete ends at the first time step
 
In your namelist.input, "restart = .false." In this case you don't need to set "step_to_output_time = .true." This is because step_to_output_time only works for restart = .true.

Somehow the model behaves strangely when inconsistent options are turned on. It is not our top priority to fix such kind of issues at present. So please stay with the consistent options.
