Default constructor.

Member Function Documentation

virtual NodeBaseBottomSmoother* NodeBiCGStabSmoother::new_bottomSmoother (  )  const [virtual]

this gets around the "no virtual constructor" rule

Implements NodeBaseBottomSmoother.

void NodeBiCGStabSmoother::setMaxIter ( int  a_max_iter  ) 

set max number of BiCGStab iterations

void NodeBiCGStabSmoother::setSolverTol ( Real  a_solverTol  ) 

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

virtual void NodeBiCGStabSmoother::doBottomSmooth ( LevelData< NodeFArrayBox > &  a_phi,
const LevelData< NodeFArrayBox > &  a_rhs,
NodeLevelOp a_levelop_ptr 
) [virtual]

Perform BiCGStab smoothing of L(a_phi) = a_rhs, where L is the operator defined in a_levelop_ptr, and the preconditioner is a_levelop_ptr->levelPreconditioner().

a_phi  data at this level, to be smoothed
a_rhs  right-hand side at this level
a_levelop_ptr  pointer to the operator

Implements NodeBaseBottomSmoother.
