ACCESS-OM2 model setup problem

Hi all,

I’d like to run a new 01deg_jra55v13_ryf_9091 simulation. This is a re-run from a simulation I completed successfully last year and I am using the same configuration since last time.

Unfortunately I now get a

FATAL from PE 2626: Error: salinity out of range with value -6.324080775145E+00 at (i,j,k) = (2034,1446, 63), (lon,lat,dpt) = ( -76.6500, 19.6529, 3377.5509 m)

abort notification when restarting the simulation again.

Andrew mentioned this could be caused by a model setup problem. Near the Antarctic coast (where my salinity drops) is where a few cells in the bathymetry were changed recently and maybe there is a mismatch between my configuration and this input field?

These are the input files for my MOM model:

- name: ocean
  model: mom
  exe: /g/data/ik11/inputs/access-om2/bin/fms_ACCESS-OM_97e3429_libaccessom2_1bb8904.x
  input:
      - /g/data/ik11/inputs/access-om2/input_08022019/mom_01deg

I am aware I am using a rather old executable and the reason for it is that this one allows me to save WMT diagnostics in temperature space. Could it be that the /g/data/ik11/inputs are not compatible anymore with my .exe files?

I think this is probably the thread with the changes made:

(lon,lat,dpt) = ( -76.6500, 19.6529, 3377.5509 m) is in the Caribbean Sea somewhere. Although I am surprised there is 3000m depth there ?

The files in /g/data/ik11/inputs/access-om2/input_08022019/mom_01deg are all from February 2019, and don’t look like they changed over time (based on their date stamps)

Hi @mauricehuguenin:

Thanks for starting this topic. @anton was quick to the mark here (thanks Anton!) and has pointed you to a useful topic that should help you out. I’m going to mark this topic with the community-help tag so that folks from COSIMA can provide any additional support, since I think this points to some legacy COSIMA experiments.

Please continue to post any additional comments/queries here!

Thanks,

Lawrence
