Multi-level preconditioner. Here, we collect all information needed for multi-level preconditioning and provide the standard interface for LAC iterative methods.
Furthermore, it needs functions void copy_to_mg(const VECTOR&) to store src in the right hand side of the multi-level method and void copy_from_mg(VECTOR&) to store the result of the v-cycle in dst.

| PreconditionMG< dim, VECTOR, TRANSFER >::PreconditionMG | ( | const MGDoFHandler< dim > & | mg_dof, |
| Multigrid< VECTOR > & | mg, | ||
| const TRANSFER & | transfer | ||
| ) |
Constructor. Arguments are the multigrid object, pre-smoother, post-smoother and coarse grid solver.
| bool PreconditionMG< dim, VECTOR, TRANSFER >::empty | ( | ) | const |
Dummy function needed by other classes.
| void PreconditionMG< dim, VECTOR, TRANSFER >::vmult | ( | VECTOR2 & | dst, |
| const VECTOR2 & | src | ||
| ) | const |
Preconditioning operator. Calls the vcycle function of the MG object passed to the constructor.
This is the operator used by LAC iterative solvers.
| void PreconditionMG< dim, VECTOR, TRANSFER >::vmult_add | ( | VECTOR2 & | dst, |
| const VECTOR2 & | src | ||
| ) | const |
Preconditioning operator. Calls the vcycle function of the MG object passed to the constructor.
| void PreconditionMG< dim, VECTOR, TRANSFER >::Tvmult | ( | VECTOR2 & | dst, |
| const VECTOR2 & | src | ||
| ) | const |
Tranposed preconditioning operator.
Not implemented, but the definition may be needed.
| void PreconditionMG< dim, VECTOR, TRANSFER >::Tvmult_add | ( | VECTOR2 & | dst, |
| const VECTOR2 & | src | ||
| ) | const |
Tranposed preconditioning operator.
Not implemented, but the definition may be needed.

SmartPointer<Multigrid<VECTOR>,PreconditionMG<dim,VECTOR,TRANSFER> > PreconditionMG< dim, VECTOR, TRANSFER >::multigrid [private] |
The multigrid object.
