pyro solves elliptic problems (like Laplace's equation or Poisson's
equation) through multigrid. This accelerates the convergence of
simple relaxation by moving the solution down and up through a series
of grids. Chapter 9 of the `pdf notes <http://bender.astro.sunysb.edu/hydro_by_example/CompHydroTutorial.pdf>`_ gives an introduction to solving elliptic equations, including multigrid.
