/*!
 * \ingroup VcfvTestProblems
 * \brief Non-isothermal gas injection problem where a air
 *        is injected into a fully water saturated medium.
 *
 * During buoyancy driven upward migration, the gas passes a
 * rectangular high temperature area. This decreases the temperature
 * of the high-temperature area and accelerates gas infiltration due
 * to the lower viscosity of the gas. (Be aware that the pressure of
 * the gas is approximately constant within the lens, so the density
 * of the gas is reduced. This more than off-sets the viscosity
 * increase of the gas at constant density.)
 *
 * The domain is sized 40 m times 40 m. The rectangular area with
 * increased temperature (380 K) starts at (20 m, 5 m) and ends at (30
 * m, 35 m).
 *
 * For the mass conservation equation, no-flow boundary conditions are
 * used on the top and on the bottom of the domain, while free-flow
 * conditions apply on the left and the right boundary. Gas is
 * injected at bottom from 15 m to 25 m at a rate of 0.001 kg/(s m^2)
 * by means if a forced inflow boundary condition.
 *
 * At the free-flow boundaries, the initial condition for the bulk
 * part of the domain is assumed, i. e.  hydrostatic pressure, a gas
 * saturation of zero and a geothermal temperature gradient of 0.03
 * K/m.
