* \brief Two-phase problem featuring some gravity-driven saturation
|
|
* fingers.
|
|
*
|
|
* The domain of this problem is sized 10cm times 1m and is initially
|
|
* dry. Water is then injected at three locations on the top of the
|
|
* domain which leads to gravity fingering. The boundary conditions
|
|
* used are no-flow for the left and right and top of the domain and
|
|
* free-flow at the bottom. This problem uses the Parker-Lenhard
|
|
* hystersis model which might lead to non-monotonic saturation in the
|
|
* fingers if the right material parameters is chosen and the spatial
|
|
* discretization is fine enough.
