Detailed Description

Mixed-hybrid model of linear Darcy flow, possibly unsteady.

Abstract class for various implementations of Darcy flow. In future there should be one further level of abstraction for general time dependent problem.

maybe TODO: split compute_one_step to : 1) prepare_next_timestep 2) actualize_solution - this is for iterative nonlinear solvers Mixed-hybrid of steady Darcy flow with sources and variable density.

solve equations:

$q= -{\mathbf{K}} \nabla h -{\mathbf{K}} R \nabla z$

$\mathrm{div} q = f$

where

is flux $[ms^{-1}]$ for 3d, $[m^2s^{-1}]$ for 2d and $[m^3s^{-1}]$ for 1d.
$\mathbf{K}$ is hydraulic tensor ( its orientation for 2d, 1d case is questionable )
$h = \frac{\pi}{\rho_0 g}+z$ is pressure head, $\pi, \rho_0, g$ are the pressure, water density, and acceleration of gravity , respectively. Assumes gravity force acts counter to the direction of the axis.
is destity or gravity variability coefficient. For density driven flow it should be
$R = \frac{\rho}{\rho_0} -1 = \rho_0^{-1}\sum_{i=1}^s c_i$
where is concentration in $kg m^{-3}$ .

The time key is optional, when not specified the equation is forced to steady regime. Using Steady TimeGovernor which have no dt constraints.

TODO: Make solution regular field (need FeSeystem and parallel DofHandler for edge pressures), then remove get_solution_vector from Equation interface. Model for transition coefficients due to Martin, Jaffre, Roberts (see manual for full reference)

TODO:

how we can reuse field values computed during assembly

Returns true is the fields involved in the time term have values that makes the time term zero. For time_global==true, it returns true if there are no field descriptors in the input list, so the fields )of the time ter) have their default values for whole simulation.
