instead of passing a "minimal" fluid state that defines the thermodynamic conditions on the domain boundary and the models calculating everything they need based on this, it is now assumed that all quantities needed by the code that computes the boundary fluxes are defined. This simplifies the boundary flux computation code, it allows to get rid of the `paramCache` argument for these methods and to potentially speed things up because quantities do not get re-calculated unconditionally. on the flipside, this requires slightly more effort to define the conditions at the boundary on the problem level and it makes it less obvious which quantities are actually used. That said, one now has the freedom to shoot oneself into the foot more easily when specifying boundary conditions and also tools like valgrind or ASAN will normally complain about undefined quantities if this happens.

* \brief Problem where dissolved nitrogen is transported with the water
|
|
* phase from the left side to the right.
|
|
*
|
|
* The model domain is 1m times 1m and exhibits homogeneous soil
|
|
* properties (\f$ \mathrm{K=10e-10, \Phi=0.4}\f$). Initially the
|
|
* domain is fully saturated by water without any nitrogen dissolved.
|
|
*
|
|
* At the left side, a free-flow condition defines a nitrogen mole
|
|
* fraction of 0.02%. The water phase flows from the left side to the
|
|
* right due to the imposed pressure gradient of \f$1e5\,Pa/m\f$. The
|
|
* nitrogen is transported with the water flow and leaves the domain
|
|
* at the right boundary where an outflow boundary condition is
|
|
* used.
