[MITgcm-support] 3D forcing for the momentum equations

[Jean-Michel Campin]

Hi Igor,

You may also want to take a look at "pkg/mypackage/" (MYPACKAGE_TENDENCY in MYPACKAGE_OPTIONS.h, 
myPa_applyTendU, myPa_applyTendV as run-time parameters).

Cheers,
Jean-Michel

Introduction¶. pkg/rbcs provides the flexibility to relax fields (temperature, salinity, ptracers, horizontal velocities) in any 3-D location, thus can be used to implement a sponge layer, or a ?source? anywhere in the domain, among other uses.. For a field (\(T\)) at every grid point the tendency is modified so that:
