constant

<code>constant()</code> creates an analytic element containing a constant head, often referred to
as the reference point.

A model of single-layer groundwater flow in steady-state
under the Dupuit-Forchheimer assumption can be created by placing
elements such as wells, area-sinks and line-sinks at arbitrary
locations in the flow field. Output variables include hydraulic head
and the discharge vector. Particle traces can be computed numerically
in three dimensions. The underlying theory is described in Haitjema
(1995) <doi:10.1016/B978-0-12-316550-3.X5000-4> and references
therein.
