 * \ingroup TestProblems
 *
 * \brief Non-isothermal three-phase gas injection problem where a hot gas
 *        is injected into a unsaturated porous medium with a residually
 *        trapped NAPL contamination.
 *
 * The domain is a quasi-two-dimensional container (cuvette). Its
 * dimensions are 1.5 m x 0.74 m. The top and bottom boundaries are
 * closed, the right boundary is a free-flow boundary allowing fluids
 * to escape. From the left, an injection of a hot water-air mixture
 * is injected. The set-up is aimed at remediating an initial NAPL
 * (Non-Aquoeus Phase Liquid) contamination in the domain.  The
 * contamination is initially placed partly into the ambient coarse
 * sand and partly into a fine sand lens.
 *
 * This simulation can be varied through assigning different boundary conditions
 * at the left boundary as described in Class (2001):
 * Theorie und numerische Modellierung nichtisothermer Mehrphasenprozesse in
 * NAPL-kontaminierten poroesen Medien, Dissertation, Eigenverlag des Instituts
 * fuer Wasserbau
 *
 * To see the basic effect and the differences to scenarios with pure
 * steam or pure air injection, it is sufficient to simulate this
 * problem to about 2-3 hours simulation time.  Complete remediation
 * of the domain requires much longer (about 10 days simulated time).
