WRST TW0/TWN in restart write #217

Open JessicaMeixner-NOAA opened 4 years ago

JessicaMeixner-NOAA commented 4 years ago

WRST assumes it's writing a restart at TWN, however, if a restart is asked for at initialization time, we could in fact write out TW0.

When we define Type 4 output for the restart file, starting at initialization time, it does not write restart000.ww3 by default. Is there an option or switch for it? Does WRST switch invoke this feature?

JessicaMeixner-NOAA commented 4 years ago

That's a good point, I think it would still be restart001.ww3 not restart000.ww3. This was reported by @ajhenrique, I'm guessing he saw this in the second set of restarts where the date YYYYMMDD.HHMMSS.restart.ww3 is written. I never really understood why you would want to write out a restart file at the beginning time though, so maybe instead there should be a check in the model to not write out the restart at initialization time, instead of the check for TW0 vs TWN. WRST should have no effect on when a restart is written, it just says write out the wind file in the restart when you write one out.

Yes, it is restart001.ww3 and it is created at t=0 but with zero sizes. Once it reaches the first time step for type 4, it will be filled. I am not sure, but the restart002.ww3 is created and filled at the second time step. The restart at t=0 does not make sense except for the check.

What about for this issue, if I create a check that you do not write a restart file at initialization time?

aliabdolali commented 3 years ago

@JessicaMeixner-NOAA Yes, this is what we need to do.

JessicaMeixner-NOAA commented 2 years ago

@aliabdolali, my plan is to close this issue as unplanned work. Any objection?

@aliabdolali @JessicaMeixner-NOAA, can this be closed as unplanned work?
