Detailed Description

template<class GO>
class Dune::PDELab::ISTLBackend_SEQ_BCGS_AMG_SSOR< GO >

Sequential BiCGStab solver preconditioned with AMG smoothed by SSOR.

Template Parameters
GOThe type of the grid operator (or the fakeGOTraits class for the old grid operator space).

Constructor & Destructor Documentation

template<class GO >
Dune::PDELab::ISTLBackend_SEQ_BCGS_AMG_SSOR< GO >::ISTLBackend_SEQ_BCGS_AMG_SSOR ( unsigned  maxiter_ = 5000,
int  verbose_ = 1,
bool  reuse_ = false,
bool  usesuperlu_ = true 
)
inline

Constructor.

Parameters
maxiter_The maximum number of iterations allowed.
verbose_The verbosity level to use.
reuse_Set true, if the Matrix to be used is always identical (AMG aggregation is then only performed once).
usesuperlu_Set false, to suppress the no SuperLU warning
