Detailed Description

Geometric agglomerated algebraic multigrid solver.

Characteristics:

Requires positive definite, diagonally dominant matrix.
Agglomeration algorithm: selectable and optionally cached.
Restriction operator: summation.
Prolongation operator: injection.
Smoother: Gauss-Seidel.
Coarse matrix creation: central coefficient: summation of fine grid central coefficients with the removal of intra-cluster face; off-diagonal coefficient: summation of off-diagonal faces.
Coarse matrix scaling: performed by correction scaling, using steepest descent optimisation.
Type of cycle: V-cycle with optional pre-smoothing.
Coarsest-level matrix solved using ICCG or BICCG.
