32 *
33 * The simulation domain is a tube with an elevated temperature on the left hand side.
34 *
35 * Initially the domain is fully saturated with water at a constant temperature.
36 * On the left hand side there is a Dirichlet boundary condition with an increased
37 * temperature and on the right hand side a Dirichlet boundary with constant pressure,
38 * saturation and temperature is applied.
39 *
40 * The results are compared to an analytical solution for a diffusion process.
41 * This problem uses the \ref OnePModel and \ref NIModel model.
