Detailed Description

Concrete LinearOpWithSolveBase subclass that adapts any Amesos_BaseSolver object.

See the LinearOpWithSolveBase interface for a description of how to use objects of this type.

Note: Clients should not generally directly create objects of this type but instead should use AmesosLinearOpWithSolveFactory. Only very sophisticated users should ever directly interact with an object through this subclass interface.

Member Function Documentation

◆ initialize()

void Thyra::AmesosLinearOpWithSolve::initialize	(	const Teuchos::RCP< const LinearOpBase< double > > &	fwdOp,
		const Teuchos::RCP< const LinearOpSourceBase< double > > &	fwdOpSrc,
		const Teuchos::RCP< Epetra_LinearProblem > &	epetraLP,
		const Teuchos::RCP< Amesos_BaseSolver > &	amesosSolver,
		const EOpTransp	amesosSolverTransp,
		const double	amesosSolverScalar
	)

First initialization.

Parameters

fwdOp	[in] The forward operator for which the factorization exists.
epetraLP	[in] The `Epetra_LinearProblem` object that was used to create the `Amesos_BaseSolver` object `*amesosSolver`. Note that the RHS and the LHS multi-vector pointers in this object will be set and unset here.
amesosSolver	[in] Contains the factored, and ready to go, `Amesos_BaseSolver` object ready to solve linear system.
amesosSolverTransp	[in] Determines if the Amesos solver should be used as its transpose or not.
amesosSolverScalar	[in] Determines the scaling factor associated with the Amesos solver. The solution to the linear solve is scaled by `1/amesosSolverScalar`.

Preconditions:

fwdOp.get()!=NULL
epetraLP.get()!=NULL
amesosSolver.get()!=NULL
*epetraLP->GetOperator() is compatible with *fwdOp
epetraLP->GetLHS()==NULL
epetraLP->GetRHS()==NULL
*amesosSolver contains the factorization of *fwdOp and is ready to solve linear systems!

Postconditions:

this->get_fwdOp().get() == fwdOp.get()
this->get_epetraLP().get() == epetraLP.get()
this->get_amesosSolver().get() == amesosSolver.get()
this->get_amesosSolverTransp() == amesosSolverTransp
this->get_amesosSolverScalar() == amesosSolverScalar

◆ extract_fwdOpSrc()

Teuchos::RCP< const LinearOpSourceBase< double > > Thyra::AmesosLinearOpWithSolve::extract_fwdOpSrc ( )

Extract the LinearOpSourceBase<double> object so that it can be modified.

Postconditions:

return.get() is the same as this->get_fwdOpSrc().get() before call.
this->get_fwdOpSrc().get()==NULL
