Member Function Documentation

apply() [1/2]

virtual void Dune::IterativeSolver< X, X >::apply ( X &  x, X &  b, double  reduction, InverseOperatorResult &  res  )

inlinevirtualinherited

Apply inverse operator with given reduction factor.

apply inverse operator, with given convergence criteria.

Warning

Right hand side b may be overwritten!

Parameters

x	The left hand side to store the result in.
b	The right hand side
reduction	The minimum defect reduction to achieve.
res	Object to store the statistics about applying the operator.

Exceptions

SolverAbort

When the solver detects a problem and cannot continue

Implements Dune::InverseOperator< X, X >.

apply() [2/2]

template<class X >

virtual void Dune::BiCGSTABSolver< X >::apply ( X &  x, X &  b, InverseOperatorResult &  res  )

inlinevirtual

Apply inverse operator.

Apply inverse operator,.

Warning

Note: right hand side b may be overwritten!

Parameters

x	The left hand side to store the result in.
b	The right hand side
res	Object to store the statistics about applying the operator.

Exceptions

SolverAbort

When the solver detects a problem and cannot continue

Note

Currently, the BiCGSTABSolver aborts when it detects a breakdown.

Implements Dune::InverseOperator< X, X >.
