How to create a TEST CASE: STRATEGY

in https://forge.ipsl.jussieu.fr/nemo/browser/branches/2015/dev_r5102_CNRS11_TestCase/NEMOGCM/TOOLS/TEST_CASES there are:

CREATE_FILES directory : python scripts to create

  1. input files: 
    1. coordinates.nc 
    2. bathy_r025.nc
  2. initial state:
    1. TScst_init_r025.nc
    2. TS_init_tprof_r025.nc
  3. forcing file:
    1. flx_r025.nc

a detailed TEST CASE: EQUATORIAL BOX

in https://forge.ipsl.jussieu.fr/nemo/browser/branches/2015/dev_r5102_CNRS11_TestCase/NEMOGCM/TOOLS/TEST_CASES/TEST_EQ_BOX01

and some examples to create a test case of this type :

Equatorial BOX, grid of 0.25 ° resolution, between latitude: -30°,30°, and longitude 0°,180°,

with zps coordinates,

with ubs schema on dynamics and on tracers, with constant TS initial state, with flux only wind (u composant), with flat bathymetry.

If you want to create a test case what you have to do?

  1. go into (branches/2015/dev_r5102_CNRS11_TestCase/)NEMOGCM/TOOLS/TEST_CASES/CREATE_FILES
  2. read README file
  3. run python make_coordinates.py to generate coordinates_r025.nc
  4. link coordinates.nc to coordinates_r025.nc
  5. run python make_bathy.py to generate bathy_meter.nc → bathy_r025.nc
  6. link bathy_meter.nc to bathy_r025.nc
  7. run python make_TScst_init.py to generate TScst_init_r025.nc (you do not need link, filename is written in namelist_cfg file)
  8. run python make_FLX.py to generate flx_r025.nc (you do not need link, filename is written in namelist_cfg file)

You choose in namelist_cfg cn_exp name and nitend.


NOTA BENE: if you change resolution (in python scripts) you need to change also in namelist_cfg:
