problems with restart


New member
Dear all,
I am running into issues with the restart option. In my submit script, I am creating namelist.input files modifying the restart_intervalls based on the lengths of the month. The rstfile should be written start of each month (e.g., rstWRF_d01_2021-10-01_00:00:00).
This procedure worked well for me before.
I am starting my simulation in September (restart = .false.), September works well, i.e., the restart file for October 01 at 00:00:00 is correctly written and simulations for October are started. However, for October then the restart file was written on October 31 at 00:00:00 (rather than at November 1 at 00:00:00), which led to the failure of the November simulation.
I am sure that the restart_interval is always correctly set, i.e.:
09 43200
10 44640
11 43200
12 44640

I now switched also from the adaptive time step to a regular time step, but this did not solve the problem. Any ideas what could go wrong?

P.S.: I just remember there was an option override restart timers ..., which is not set in my namelist files ... Maybe this will solve the issue.
Please add the option below to your namelist.input (i.e., namelist.input_test_10.txt)

override_restart_timers = .true.,

then try again for your October run.
