Detailed Description

template<class Operator, class Comm>
class Opm::PreconditionerFactory< Operator, Comm >

This is an object factory for creating preconditioners. The user need only interact with the factory through the static methods addStandardPreconditioners() and create(). In addition a user can call the addCreator() static method to add further preconditioners.

◆ addCreator() [1/2]

template<class Operator , class Comm >
void Opm::PreconditionerFactory< Operator, Comm >::addCreator ( const std::string &  type,
Creator  creator 
)
static

Add a creator for a serial preconditioner to the PreconditionerFactory. After the call, the user may obtain a preconditioner by calling create() with the given type string as a parameter contained in the property_tree.

Parameters
typethe type string we want the PreconditionerFactory to associate with the preconditioner.
creatora function or lambda creating a preconditioner.

◆ addCreator() [2/2]

template<class Operator , class Comm >
void Opm::PreconditionerFactory< Operator, Comm >::addCreator ( const std::string &  type,
ParCreator  creator 
)
static

Add a creator for a parallel preconditioner to the PreconditionerFactory. After the call, the user may obtain a preconditioner by calling create() with the given type string as a parameter contained in the property_tree.

Parameters
typethe type string we want the PreconditionerFactory to associate with the preconditioner.
creatora function or lambda creating a preconditioner.

◆ create() [1/3]

template<class Operator , class Comm >
PreconditionerFactory< Operator, Comm >::PrecPtr Opm::PreconditionerFactory< Operator, Comm >::create ( const Operator &  op,
const PropertyTree &  prm,
const Comm &  comm,
std::size_t  pressureIndex = std::numeric_limits<std::size_t>::max() 
)
static

Create a new parallel preconditioner and return a pointer to it.

Parameters
opoperator to be preconditioned.
prmparameters for the preconditioner, in particular its type.
commcommunication object (typically OwnerOverlapCopyCommunication).
Returns
(smart) pointer to the created preconditioner.

◆ create() [2/3]

template<class Operator , class Comm >
PreconditionerFactory< Operator, Comm >::PrecPtr Opm::PreconditionerFactory< Operator, Comm >::create ( const Operator &  op,
const PropertyTree &  prm,
const std::function< Vector()> &  weightsCalculator,
const Comm &  comm,
std::size_t  pressureIndex = std::numeric_limits<std::size_t>::max() 
)
static

Create a new parallel preconditioner and return a pointer to it.

Parameters
opoperator to be preconditioned.
prmparameters for the preconditioner, in particular its type.
commcommunication object (typically OwnerOverlapCopyCommunication).
weightsCalculatorCalculator for weights used in CPR.
Returns
(smart) pointer to the created preconditioner.

◆ create() [3/3]

template<class Operator , class Comm >
PreconditionerFactory< Operator, Comm >::PrecPtr Opm::PreconditionerFactory< Operator, Comm >::create ( const Operator &  op,
const PropertyTree &  prm,
const std::function< Vector()> &  weightsCalculator = {},
std::size_t  pressureIndex = std::numeric_limits<std::size_t>::max() 
)
static
