 *
 * \brief Problem where \f$CO_2\f$ is injected under a low permeable
 *        layer at a depth of 2700m.
 *
 * The domain is sized 60m times 40m and consists of two layers, one
 * which is moderately permeable (\f$K = 10^{-12}\;m^2\f$) for \f$ y >
 * 22\; m\f$ and one with a lower intrinsic permeablility (\f$
 * K=10^{-13}\;m^2\f$) in the rest of the domain.
 *
 * \f$CO_2\f$ gets injected by means of a forced-flow boundary
 * condition into water-filled aquifer, which is situated 2700m below
 * sea level, at the lower-right boundary (\f$5m<y<15m\f$) and
 * migrates upwards due to buoyancy. It accumulates and eventually
 * enters the lower permeable aquitard.
 *
 * The boundary conditions applied by this problem are no-flow
 * conditions on the top bottom and right boundaries and a free-flow
 * boundary condition on the left. For the free-flow condition,
 * hydrostatic pressure is assumed.
