Getting a perfect restart with ROMS

[lanerolle]

Is it possible with a suitable set of values for NRREC and LCYCLE, etc.
(in the toms.in/ocean.in input file) to achieve a perfect restart computation with
ROMS - so that the restart computation will proceed as if the original
computation was uninterrupted? As ROMS has a higher order time marching
scheme, at each restart designation (multiple of NRST), it would be necessary
to write out multiple (>=2) consecutive time-slabs of information but it appears
that only one set of information is written into the restart netcdf file and hence
a perfect restart does not appear to be feasible. Is this correct?

This is correct. In the days of SPEM, we achieved perfect restart by doing a low-order timestep after each restart record was written. This has been deemed a silly thing to do and has been taken out in ROMS. Imperfect restart is the least of my worries.
