* \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.
