The domain has a size of 60 x 60 m and contains two low-permeable lenses. Initially, the domain is fully water saturated and the fictitious component is injected through the middle portion of the upper boundary by means of a Neumann boundary condition. The remaining parts of the upper and the entire lower boundary are Neumann no-flow while on the two lateral sides Dirichlet boundary conditions are applied (hydrostatic conditions for the pressure and zero saturation).
