Detailed Description

template<class T>
class MergeSolver< T >

Elliptic solver using the BiCGStab algorithm that turns the bottom solve into a single grid and solves on one processor if it can.

Member Function Documentation

setHomogeneous()

template<class T >

virtual void MergeSolver< T >::setHomogeneous ( bool  a_homogeneous )

inlinevirtual

reset whether the solver is homogeneous.

Reimplemented from BiCGStabSolver< LevelData< T > >.

define()

template<class T >

virtual void MergeSolver< T >::define ( LinearOp< LevelData< T > > *  a_op, bool  a_homogeneous = false  )

inlinevirtual

define the solver. a_op is the linear operator. a_homogeneous is whether the solver uses homogeneous boundary conditions.

Reimplemented from BiCGStabSolver< LevelData< T > >.

setConvergenceMetrics()

template<class T >

virtual void MergeSolver< T >::setConvergenceMetrics ( Real  a_metric, Real  a_tolerance  )

inlinevirtual

Set a convergence metric, along with solver tolerance, if desired.

Default implementation does nothing, since there are probably cases (liked direct solves), where this has no real meaning.

Reimplemented from BiCGStabSolver< LevelData< T > >.

References MergeSolver< T >::solve().

solve()

template<class T >

void MergeSolver< T >::solve ( LevelData< T > &  a_phi, const LevelData< T > &  a_rhs  )

virtual

only overridden virtual function

Reimplemented from BiCGStabSolver< LevelData< T > >.
