Overview

WVForcing is an abstract class that defines how forcing gets added to a WVTransform. You can use one the built-in forcing operations, or make your own.

Forcing is applied at two stages:

1. in the spatial domain to
   1. non-hydrostatic flow d/dt(u,v,w,eta) = (Fu,Fv,Fw,Feta) or
   2. hydrostatic flow d/dt(u,v,eta) = (Fu,Fv,Feta) and
2. in the spectral domain to d/dt(Ap,Am,A0) = (Fp,Fm,F0)

Each WVForcingFluxOperation must choose one of the two options and override either,

1. [Fu, Fv, Fw, Feta] = addSpatialForcing(wvt, Fu, Fv, Fw, Feta) or,
2. [Fp, Fm, F0] = addSpectralForcing( wvt, Fp, Fm, F0)

Regardless of which method is chosen, the energy flux from the forcing can always be deduced at each moment in time.
