Detailed Description

A stress package that reduces a withdrawal, such as the Well Package with AUTO_FLOW_REDUCE, multiplies the requested rate by a factor that falls from one to zero as the fluid runs out. On its own the package judges that from the cell: the factor tapers over a length measured up from the cell bottom, and only a convertible cell can run dry.

A flow formulation may know better how much of the fluid being withdrawn the cell holds: a sharp interface knows the elevation range the fluid occupies, and an unsaturated-flow formulation knows its saturation. Such a formulation implements this interface and returns the factor itself, with its derivative, so the stress package applies it without knowing which formulation provided it, or whether one did at all.
