Detailed Description

TransferMap represents a mapping of degrees of freedom from a source GridFunction to a destination GridFunction.

This map can be constructed from a parent Mesh to a SubMesh or vice versa. Additionally one can create it between two SubMeshes that share the same root parent. In this case, a supplemental FiniteElementSpace is created on the root parent Mesh to transfer degrees of freedom.

Constructor & Destructor Documentation

TransferMap() [1/2]

TransferMap::TransferMap	(	const FiniteElementSpace &	src,
		const FiniteElementSpace &	dst )

Construct a new TransferMap object which transfers degrees of freedom from the source FiniteElementSpace to the destination FiniteElementSpace.

Parameters

src	The source FiniteElementSpace
dst	The destination FiniteElementSpace

Definition at line 18 of file transfermap.cpp.

TransferMap() [2/2]

TransferMap::TransferMap	(	const GridFunction &	src,
		const GridFunction &	dst )

Construct a new TransferMap object which transfers degrees of freedom from the source GridFunction to the destination GridFunction.

Equivalent to creating the TransferMap from the finite element spaces of each of the GridFunctions.

Parameters

src	The source GridFunction
dst	The destination GridFunction

Definition at line 133 of file transfermap.cpp.

Member Function Documentation

Transfer()

void TransferMap::Transfer	(	const GridFunction &	src,
		GridFunction &	dst ) const

Transfer the source GridFunction to the destination GridFunction.

Uses the precomputed maps for the transfer.

Parameters

src	The source GridFunction
dst	The destination GridFunction
