Poisson solvers on a SAMRAI hierarchy

SAMRAI provides a single-level and a hierarchy solver for the cell-centered Poisson equations. The single-level solver uses the HYPRE library. The the hierarchy solver uses an FAC formulation, possibly using the single-level solver on the coarsest level. A Robin boundary condition interface is defined to coordinate between the solvers the boundary conditions for a scalar quantity. Several library-provided implementations of this interface are available, and user-defined implementations are supported.
