coupling_*.in file and Wubot

#1 Unread post by nganju »

To hopefully save someone else a little time...
In the supplied examples of Externals/coupling_*.in files, SWAN does not provide bottom orbital velocites or wave dissipation to ROMS. If you want this field passed, you need to add the Wubot (or Wdiss) field to Export(waves) and Import(ocean). If you are using a BBL model (and not using SSW_CALC_UB), and hoping to account for wave-current interaction, ROMS will use a default value (1e-10) if SWAN doesn't pass this field to ROMS (and therefore no wave-current interaction will be computed).

Code: Select all

Nexport(ocean) = 4
 Nexport(waves) = 5

  Export(ocean) = bath  \
                  SSH   \
                  Ubar  \
                  Vbar

  Export(waves) = Wdir  \
                  Wamp  \
                  Wlen  \
                  Wptop \
                  Wpbot 

! Import fields per model, [1:Nimport(...)] string values are expected per
! coupled model. If there is no field to import, set
!
!      Nimport(...) = 0
!       Import(...) = NONE

 Nimport(ocean) = 5
 Nimport(waves) = 4

  Import(ocean) = Wdir  \
                  Wamp  \
                  Wlen  \
                  Wptop \
                  Wpbot 

  Import(waves) = bath  \
                  SSH   \
                  Ubar  \
                  Vbar
