Documentation of the TH2M/H2 McWorther benchmark
The following discussion from !3798 (merged) should be addressed:
The resulting saturation profile can be compared using a (semi-)analytical solution (http://mmg.fjfi.cvut.cz/~fucik/index.php?page=exact).
How is the OGS solution compared to the semi-analytical solution?
A corresponding documentation page with plot against the semi-analytical solution should be set up discussing the differences. Plots of the solution and the error are to be added.
