Member Function Documentation

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

{\bf data modification functions} Perform BiCGStab smoothing of L(a_phi) = a_rhs; \ L is the operator defined in a_levelopPtr, and the preconditioner is a_levelopPtr->smooth(). {\bf Arguments:}\ a_phi (modified): the data at this level.\ a_rhs (not modified): right-hand side.\ a_levelopPtr (not modified): pointer to the operator.\ Implements NodeBaseBottomSmoother.

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

this gets around the "no virtual constructor" rule Implements NodeBaseBottomSmoother.

void NodeBiCGStabSmoother::setMaxIter (  int    a_max_iter )

{\bf parameter-setting functions} set max number of BiCGStab iterations

void NodeBiCGStabSmoother::setSolverTol (  Real    a_solverTol )

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

void NodeBiCGStabSmoother::setVerbose (  bool    a_verbose )

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