MultigridSolver< Grd, domain_type > Class Template Reference

#include <multiGridStacks.hh>

Detailed Description

template<class Grd, class domain_type>
class MultigridSolver< Grd, domain_type >

MultigridSolver realizes a classical v-cycle multigrid solver

yet truncation criterion is relative defect tolerance ||Ax-b||_2/||b||_2 < maxTol

example usage:

ProlongationStack<Dune::UGGrid<dim> > ps( gridManager.grid() ); MlStack<Dune::UGGrid<dim> > myStack( ps , bcrsMatrix ); MultigridSolver<Grid> MGSolver( ps , myStack , JacobiRelaxFactor , maxIter , mgSmoothings, maxTol ); MGSolver.mgSolve( solution , rhs );
