[MITgcm-support] Eta relaxation to obcs values

[eliyahu biton]

Hello suporting list and others
I'm trying to use real fresh water flux, and yet mantain reasonable sea 
level values (as the evaporation rate from my basin's surface is ~2m/year).
To do so I set the flag  useRealFreshWaterFlux to True, and I have one 
OBCS in order to compansate the evaporation process (by relaxation of 
the sea level values (eta) to the boundary values [set to zero by defult]) .
I ran two experiments, one with non linear free surface and one with 
linear free surface, both of them showed consistent dropping in sea 
level and no relaxation to sea level boundary condition.
I know that there is an option to use OBCSprescrib option where water 
fluxes at the boundary are read from inputted files, but I would prefer 
to use relaxation to sea level such that the fluxes at the boundary will 
be calculated by the model.
Any suggestion?
thanks a lot, Eli.
