Detailed Description

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

void DarcyMH::assembly_linear_system ( )

protectedvirtual

Here is the caller graph for this function:

void DarcyMH::assembly_mh_matrix ( MultidimAssembler ma )

protected

Part of per element assembly that is specific for MH and LMH respectively.

This implemnets MH case:

compute conductivity scaling
assembly source term
no time term, managed by diagonal extraction etc. Abstract assembly method used for both assembly and preallocation. Assembly only steady part of the equation. TODO:
use general preallocation methods in DofHandler
include time term
add support for Robin type sources
support for nonlinear solvers - assembly either residual vector, matrix, or both (using FADBAD++)
