Detailed Description

Implements BiCGStab as a bottom smoother for LevelOp-derived classes.

The BiCGStabSmoother class implements the BiCGStab algorithm for LevelOp-derived classes

Constructor & Destructor Documentation


constructor, destructor default constructor

virtual BiCGStabSmoother::~BiCGStabSmoother   [virtual]


Member Function Documentation

virtual void BiCGStabSmoother::doBottomSmooth LevelData< FArrayBox > &    a_phi,
const LevelData< FArrayBox > &    a_rhs,
LevelOp   a_levelop_ptr

do smoothing

performs BiCGStab smoothing of L(a_phi) = a_rhs; L is the operator defined in a_levelop_ptr, and the preconditioner is a_levelop_ptr->smooth

Implements BaseBottomSmoother.

virtual BaseBottomSmoother* BiCGStabSmoother::new_bottomSmoother   const [virtual]

this gets around the "no virtual constructor" rule

Implements BaseBottomSmoother.

void BiCGStabSmoother::setMaxIter int    a_max_iter

set maximum number of BiCGStab iterations

set max number of BiCGStab iterations

void BiCGStabSmoother::setSolverTol Real    a_solver_tol

set solver tolerance

set solver tolerance (amount residual must be decreased, etc)

void BiCGStabSmoother::setVerbose bool    a_verbose

set verbosity level

set whether i/o is done when solving (default is false)
