restart error with nested grid

#1 Unread post by undave »

Hello Forum,
I am trying a restart of a COAWST compilation with a nested grid in ROMS. The job ran for approximately 7200 timesteps before bombing. For my restart, I set NRREC to -1, and put my two restart files as the initial condition files. Also I renamed these files so that they would not be overwritten. I reduced NHIS to see if I could find the reason for the job bombing as it was not apparent from examining the history files. I get error messages from the refined (nested) grid like:

LBC_GETATT - inconsistent western lateral boundary condition for variable: mud_01
restart file LBC keyword = Nes
but assigned structure switch: S(1, 8,2)%nested = F
check input script LBC keyword for consitency ...
restart file: /projects/dafu8991/COAWST/CALUSNEST2/calusa_rst_ref_bkup.nc

I get a similar message for each boundary and for a sand_01 variable that was also included. To which structure switch is the message referring? I looked in both my sediment.in and ocean.in but could not find a relevant switch. Also, why would it run for so long on the original run, but bomb right away with the restart if no other settings were changed? I searched the forum but could not find a similar error message.
Thanks,
David

the mud and sand LBC's are in the sediment.in file, such as for Projects/Inlet_test/Refined

LBC(isTvar) == Gra Clo Gra Gra \ ! idsed(:), compact
Nes Nes Nes Nes

Yours would be different on the first line, but the 2nd line should be Nes.

yes, they are set as follows in the sediment.in file

LBC(isTvar) == Gra Gra Clo Gra ! idsed(:), compact
Nes Nes Nes Nes

Yes that was it :oops: Wonder why it did not bomb right away in the original run?
Thanks!
