abstract = {The report gives an introduction to the multigrid
iterative solvers in Diffpack. It is meant as a tutorial
for the use of iterative solvers, preconditioners and
nonlinear solvers based on multigrid methods. The first
steps towards this efficient equation solvers are guided by
a couple of examples and exercises. Since multigrid is a
recipe to construct solution algorithms rather than
black-box algorithms itself, there is lots of freedom for
the user to tailor the actual solver. Reflecting this fact
there are lots of possibilities to use the appropriate
classes in Diffpack. Hence there is much advice needed not
to get started, but also to use the methods efficiently.
The exercises are meant to give some experience needed for
applications and questions not covered in this introductory
report.}
