Hello everybody,
I was able to run successfully roms using analytical initial conditions. Now I want to start a simulation using the last time record of my previous simulation, but for a longer time.
How can I save the ocean_ini.nc file that could be used for a subsequent simulation?
Initially, my simulation is for 5000 iterations, the next one should be for 1000 so first I used the NREC == 0 and then once I got the solution used in the next simulation NRREC == -1, but got the following error
NETCDF_OPEN - unable to open existing NetCDF file:
ocean_ini.nc
call from: checkvars.F
Elapsed CPU time (seconds):
Thread # 0 CPU: 0.700

Nonlinear model elapsed time profile:

All percentages are with respect to total time = 0.700

re-inirialization file
Re: re-inirialization file
We usually save to a restart file every NRST timesteps, then use this as the next initial condition. So on restart, you have to change NRREC and also INI_NAME. Do you have the ocean_ini.nc file? Was it written as a history, averages, or restart file? The restart file should contain everything you will need on restart.
It looks like ANA_INITIAL only calls ana_initial when nrrec==0, so you won't need to recompile.
