Dear Stéphane, I did not write the fs2000/fs2000_analytic_derivation.mod, but I think it can be safely taken out. I was always wondering what the fs2000-folder is about except for making sure the shipped example works.

I hardly see the difference with the integration test in the analytical_derivates subfolder, except that in fs2000 subfolder we do not provide the analytical steady state.
