add a fwb scheme without any bouyancy flux ?

Description

Context

NEMO is able to check and correct the fresh water budget. The correction of the fw budget is done via the 'emp' variable. This leads to creation of a bouyancy flux.

For some applications, it could be handy to simply get rid of the unbalance in the fw budget without creation of a bouyancy flux (to avoid spurious convection for example). This can simply be done by adding a corrective salt content flux (similar to what is done for the heat) in sbcfwb.F90. An example is available in ISOMIP+/MY_SRC

Analysis

If the option of having this extra choice in sbcfwb retained, how to do it:

  • adding a fourth choice in nn_fwb (namsb namelist block) ⇒ the easiest (as in ISOMIP+)
  • adding a flag ln_fwb in namsbc (maybe more in the philosophy of namsbc) and a namelist block namsbc_fwb with nn_fwb and a logical flag ln_nobouy (?) to remove any bouyancy flux due to the fwb correction.
