Andreas Lauser 6fcb16c0c9 fix a signedness issue when retrieving parameters
the issue only bites if the tests are compiled in debug mode, so it
has only been discovered now.

* \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.
