Detailed Description

Does nothing as a bottom smoother.

The NoOpSmoother class is a bottom smoother for LevelOp-derived classes which does nothing (mostly as a debugging test option)

Member Function Documentation

virtual void NoOpSmoother::doBottomSmooth (  LevelData< FArrayBox > &    a_phi, const LevelData< FArrayBox > &    a_rhs, LevelOp *    a_levelopPtr )  [virtual]

Do (no) smoothing. True to its name, this class does nothing in this functino Implements BaseBottomSmoother.

virtual BaseBottomSmoother* NoOpSmoother::new_bottomSmoother (    )  const [virtual]

This gets around the "no virtual constructor" rule. Implements BaseBottomSmoother.

virtual void NoOpSmoother::setConvergenceMetric (  Real    a_metric, int    a_comp = 0 )  [inline, virtual]

sets metric to judge convergence (normally norm(rhs) of outer problem To make the iterative solver convergence more consistent, the solver will consider itself "solved" if the residual is reduced to epsilon*metric, where epsilon is the solver tolerance (set by setSolverTol). A good starting point for the metric is the norm of the RHS of the original problem (i.e. the rhs sent in to LevelSolver or AMRSolver). Default value is 1.0. Implements BaseBottomSmoother.

virtual void NoOpSmoother::setSolverTol (  Real    a_tol )  [inline, virtual]

this doesn't really do anything, but is required by BaseBottomSmoother Implements BaseBottomSmoother.
