 As discussed in :doc:`stokes.py`, the hard part remains the construction of the :math:`(A+\gamma B^TM^{-1}B)^{-1}` to precondition the (1,1) block.

 Notice that while the smoother is very similar to the one used in :doc:`stokes.py`, for the coarse correction we are here using h-multigrid and not p-multigrid. ::
