Detailed Description

A class which builds a diagnostic operator to wrap the application of the inverse operator. Also times the construction of the inverse operator.

For construction purposes this class can be initialized using a parameter list. Most often used in conjuncition with an InverseLibrary object. In particular the relevant parameters are

<Parameter name="Type" type="string" value="Diagnostic Inverse"/>
<Parameter name="Inverse Factory" type="string" value="<Some Inverse Factory>"/>
<!-- Optional, use if Inverse Factory is an iterative solver, e.g. -->
<Parameter name="Preconditioner Factory" type="string" value="<Some Other Inverse Factory>"/>
<Parameter name="Descriptive Label" type="string" value="<Some Label>"/>
<Parameter name="Print Residual" type="bool" value="false"/>

Member Function Documentation

LinearOp Teko::DiagnosticPreconditionerFactory::buildPreconditionerOperator	(	LinearOp &	lo,
		PreconditionerState &	state
	)		const

virtual

Function that is called to build the preconditioner for the linear operator that is passed in.

This function builds a preconditioner based on the passed in LinearOp.

Parameters

[in]	lo	Source linear operator that is to be preconditioned.
[in]	state	An object associated with this operator to store the preconditioner state.

Returns: The preconditioner as a linear operator (i.e. to perform a matrix-vector operation simply call "apply").

Implements Teko::PreconditionerFactory.

void Teko::DiagnosticPreconditionerFactory::initializeFromParameterList ( const Teuchos::ParameterList & settings )

virtual

This function builds the internals of the preconditioner factory from a parameter list.

This function builds the internals of the preconditioner factory from a parameter list. Furthermore, it allows a preconditioner factory developer to easily add a factory to the build system. This function is required for building a preconditioner from a parameter list.

Parameters

[in] settings Parmaeter list to use as the internal settings

Teuchos::RCP< Teuchos::ParameterList > Teko::DiagnosticPreconditionerFactory::getRequestedParameters ( ) const

virtual

Request the additional parameters this preconditioner factory needs.

Request the additonal parameters needed by this preconditioner factory. The parameter list will have a set of fields that can be filled with the requested values. These fields include all requirements, even those of the sub-solvers if there are any. Once correctly filled the object can be updated by calling the updateRequestedParameters with the filled parameter list.

Returns: A parameter list with the requested parameters.

Reimplemented from Teko::PreconditionerFactory.

Definition at line 229 of file Teko_DiagnosticPreconditionerFactory.cpp.

bool Teko::DiagnosticPreconditionerFactory::updateRequestedParameters ( const Teuchos::ParameterList & pl )

virtual

Update this object with the fields from a parameter list.

Update the requested fields using a parameter list. This method is expected to pair with the getRequestedParameters method (i.e. the fields requested are going to be update using this method).

Parameters

[in] pl Parameter list containing the requested parameters.

Returns: If the method succeeded (found all its required parameters) this method returns true, otherwise it returns false.
