now the generic part of the update of the solution vector is done in the base class and the derived classes can chose to only do the update of the primary variables of the individual DOFs.

* \brief A water infiltration problem with a low-permeability lens
|
|
* embedded into a high-permeability domain.
|
|
*
|
|
* The domain is rectangular. The left and right boundaries are
|
|
* free-flow boundaries with fixed water pressure which corrosponds to
|
|
* a fixed saturation of \f$S_w = 0\f$ in the Richards model, the
|
|
* bottom boundary is closed. The top boundary is also closed except
|
|
* for an infiltration section, where water is infiltrating into an
|
|
* initially unsaturated porous medium. This problem is very similar
|
|
* the the \c LensProblem, with the main difference being that the domain
|
|
* is initally fully saturated by gas instead of water and water
|
|
* instead of a \c DNAPL infiltrates from the top.
