Introduction

The purpose of this part of the manual is to introduce the NEMO reference configurations. These configurations are offered as means to explore various numerical and physical options, thus allowing the user to verify that the code is performing in a manner consistent with that we are running. This form of verification is critical as one adopts the code for his or her particular research purposes. The test cases also provide a sense for some of the options available in the code, though by no means are all options exercised in the reference configurations.

Configuration is defined mainly through the namcfg namelist variables:

!-----------------------------------------------------------------------
&namcfg     !   parameters of the configuration
!-----------------------------------------------------------------------
   cp_cfg      =  "default"            !  name of the configuration
   cp_cfz      =  "no zoom"            !  name of the zoom of configuration
   jp_cfg      =       0               !  resolution of the configuration
   jpidta      =      10               !  1st lateral dimension ( >= jpi )
   jpjdta      =      12               !  2nd    "         "    ( >= jpj )
   jpkdta      =      31               !  number of levels      ( >= jpk )
   jpiglo      =      10               !  1st dimension of global domain --> i =jpidta
   jpjglo      =      12               !  2nd    -                  -    --> j =jpjdta
   jpizoom     =       1               !  left bottom (i,j) indices of the zoom
   jpjzoom     =       1               !  in data domain indices
   jperio      =       0               !  lateral cond. type (between 0 and 6)

                                       !  = 6 cyclic East-West AND North fold F-point pivot
   ln_use_jattr = .false.              !  use (T) the file attribute: open_ocean_jstart, if present
                                       !  in netcdf input files, as the start j-row for reading
