L 2 (Ω × (0, t f)) error as a function of the mesh size for the scheme (28) in the isotropic case κ = 1 (solid red) and anisotropic case κ = 20 (solid blue) corresponding to upstream mobilities (29). Comparison with the solution to the linear scheme (43) in the isotropic case (dashed red) and anisotropic case (dashed blue).
