cap_restart

This file contains a single datetime in YYYYMMDD hhmmss format. The datetime specifies the restart file that will be read from disk at the start of the GCHP simulation. It also overrides the value of BEG_DATE specified in CAP.rc.

Let’s consider an example. Say you are going to run a 1-day GCHP simulation starting at 00 GMT on 2019-07-01. The setCommonRunSettings.sh script will set the datetime in cap_restart to:

20190701 000000

as this is the starting datetime for the simulation.

Upon successful completion of the GCHP simulation, the cap_restart file is updated to contains the date when the restart was last written (which is the same as the end date of the previous simulation):

20190702 000000

If you wish to re-run for 2019-07-01, you must change the datetime in cap_restart back to 20190701 000000. Otherwise, GCHP will read the restart file for 2019-07-02 once the next simulation starts.
