Detailed Description

ParTransferMap represents a mapping of degrees of freedom from a source ParGridFunction to a destination ParGridFunction.

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

Constructor & Destructor Documentation

ParTransferMap() [1/2]

ParTransferMap::ParTransferMap	(	const ParFiniteElementSpace &	src,
		const ParFiniteElementSpace &	dst )

Construct a new ParTransferMap object which transfers degrees of freedom from the source ParFiniteElementSpace to the destination ParFiniteElementSpace.

Parameters

src	The source ParFiniteElementSpace
dst	The destination ParFiniteElementSpace

Definition at line 22 of file ptransfermap.cpp.

ParTransferMap() [2/2]

ParTransferMap::ParTransferMap	(	const ParGridFunction &	src,
		const ParGridFunction &	dst )

Construct a new ParTransferMap object which transfers degrees of freedom from the source ParGridFunction to the destination ParGridFunction.

Equivalent to creating the ParTransferMap using the spaces on which the ParGridFunctions are defined.

Parameters

src	The source ParGridFunction
dst	The destination ParGridFunction

Definition at line 137 of file ptransfermap.cpp.

Member Function Documentation

Transfer()

void ParTransferMap::Transfer	(	const ParGridFunction &	src,
		ParGridFunction &	dst ) const

Transfer the source ParGridFunction to the destination ParGridFunction.

Uses the precomputed maps for the transfer.

Parameters

src	The source ParGridFunction
dst	The destination ParGridFunction
