PCGAMGType

 type of generalized algebraic multigrid (PCGAMG) method

Synopsis

typedef const char *PCGAMGType;
#define PCGAMGAGG         "agg"
#define PCGAMGGEO         "geo"
#define PCGAMGCLASSICAL   "classical"



  PCGAMGAGG - (the default) smoothed aggregation algorithm, robust, very well tested

  PCGAMGGEO - geometric coarsening, uses mesh generator to produce coarser meshes, limited to triangles, not well tested

  PCGAMGCLASSICAL - classical algebraic multigrid preconditioner, incomplete, poorly tested
