Setting restart file frequency in WW3 #239

Open anton-seaice opened 4 days ago

anton-seaice commented 4 days ago

In the reproducibility CI workflow, the runlength is set to three hours.

For access-om3-wav-configs ,this causes the run to fail, as WW3 doesn't write a restart file at the end of the three hours.

See

The restart time can be changed through the date%restart%stride value in wav_in, so we could update the 'model-config-tests' to write this field. I think a better approach would be to update the nuopc drier for WW so the restart%stride is overwritten by the driver.

It looks like there is an option the use the nuopc stop times already:

logical                 :: user_restalarm = .false.      !< logical flag for user to set restart alarms
                                                           !! using ESMF. If restart_option is present as config
                                                           !! option, user_restalarm will be true and will be
                                                           !! set using restart_option, restart_n and restart_ymd

which is getting deprecated and becoming the default:
