Detailed Description

template<class Scalar = DefaultScalar, class LocalOrdinal = DefaultLocalOrdinal, class GlobalOrdinal = DefaultGlobalOrdinal, class Node = DefaultNode>
class MueLu::InterfaceAggregationFactory< Scalar, LocalOrdinal, GlobalOrdinal, Node >

Factory for building aggregates for Lagrange multipliers in surface-coupled problems.

Context, assumptions, and use cases

This factory is intended to be used for saddle-point systems of surface-coupled problems, where constraints are enforced with Lagrange multipliers. In addition to the primal unknowns, Lagrange multipliers are considered as dual unknowns. The presence of Lagrange multipliers make this a primal/dual problem.

It is assumed that each primal slave-side interface node (carrying primal unknowns) is replicated with a dual node carrying the dual unknowns. While the number of degrees of freedom (DOFs) per dual node is required to be constant for all dual nodes, the number of dual DOFs per node can differ from the number of primal DOFs per node.

Idea

This factory will generate aggregates for the dual nodes such that they "match" the aggregates of their primal counterpart. Instead of performing an actual aggregation procedure on the dual nodes, we grep the existing primal aggregates and use a user-given mapping of dual-to-primal node IDs to create the dual aggregates.

Input/output of this factory

User parameters of InterfaceAggregationFactory

Parameter	type	default	validated	requested	description
A	Factory	null	*	*	Generating factory of the matrix A
Aggregates	Factory	null	*	*	Generating factory of the aggregates (of type "Aggregates" produced, e.g., by the UncoupledAggregationFactory)
Dual/primal mapping strategy	string	vague	*	*	Chosen strategy and type of input data to generate dual/primal mappings
DualNodeID2PrimalNodeID	Factory	null	*	*	Generating factory of the fine dual-to-primal node mapping
Primal interface DOF map	Factory	null	*	*	Generating factory of the fine row map of primal interface degrees of freedom

The * in the master.xml column denotes that the parameter is defined in the master.xml file.
The * in the validated column means that the parameter is declared in the list of valid input parameters (see GetValidParameters() ).
The * in the requested column states that the data is requested as input with all dependencies (see DeclareInput() ).

Remarks

This factory support multiple dual/primal mapping strategies based on different inputs. They are:

node-based: The mapping of dual-to-primal node IDs, DualNodeID2PrimalNodeID, is of data type std::map<LocalOrdinal,LocalOrdinal>. The 'key' refers to the local ID of the dual node, while the 'value' represents the local ID of its primal counterpart.
dof-based: The row map of primal interface degrees of freedom (DOFs) is a subset of the row map of all primal DOFs. It only contains the primal DOFs of interface nodes, that also carry a Lagrange multiplier in the context of a mortar method.

Build dual aggregates based on a given dual-to-primal node mapping.

Parameters

[in]	prefix	Prefix for screen output
	in/out]	currentLevel Level on which the aggregation needs to be performed

		Level &	currentLevel
	)		const

private

Build dual aggregates based on a given interface row map of the primal and dual problem.

The row map of the interface portion of the primal problem corresponds to the row map of the dual problem. This correspondence is exploited to form the dual aggregates based on available primal aggregates.

Note: In the context of mortar methods, the two maps correspond to the range and domain map of the slave-sided mortar operator \(D\), which connects primal interface unknowns and dual unknowns.

Parameters

[in]	prefix	Prefix for screen output
	in/out]	currentLevel Level on which the aggregation needs to be performed
