30 *
31 * Nitrogen is dissolved in the water phase and
32 * is transported with the water flow from the left side to the right.
33 *
34 * The model domain is specified in the input file and
35 * we use homogeneous soil properties.
36 * Initially, the domain is filled with pure water.
37 *
38 * At the left side, a Dirichlet condition defines the nitrogen mole fraction.
39 * The water phase flows from the left side to the right if the applied pressure
40 * gradient is >0. The nitrogen is transported with the water flow
41 * and leaves the domain at the boundary, where again Dirichlet boundary
42 * conditions are applied.
43 *
44 * This problem uses the \ref OnePNCModel model.
