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:
where
where is concentration in .
The time key is optional, when not specified the equation is forced to steady regime. Using Steady TimeGovernor which have no dt constraints. Model for transition coefficients due to Martin, Jaffre, Roberts (see manual for full reference)
TODO:
TODO: Remove in future. It is supposed not to be improved anymore, however it is kept functioning aside of the LMH lumped version until the LMH version is stable and optimized.

This method should initialize fields of the equation. All members (e.g. number of components) that are necessary for the field initialization must be set between construction and call of initialize. After this method the upper level coupling may set sharing of some fields between equations.

There may be fields that can not be initialized in the initialize method as they are provided by the coupling. Fields coming from coupling has to be set after the initialize method and before zero_time_step.

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. If time_global==false (default), only the actual values are considered.
