[MITgcm-support] useOBCSsponge

[Dmitri Leonov]

Hello,

Is the "useOBCSsponge" option ready to be used: in general and with 
non-hydrostatic dynamics in particular?

Only u and v (also t and s but not w) are relaxed over 'spongeThickness' 
grid points.
But in the non-hydrostatic mode, w is prescribed at the boundary. That 
may cause a sharp gradient of w (?)
Does it mean that some modifications are needed (adding another 
subroutine to obcs_sponge.F, to be called from CALC_GW)?

Thanks,
Dmitri
