IBTK::LibMeshSystemIBVectors Class Reference

Class LibMeshSystemIBVectors is a convenience class that manages access to libMesh vectors for the same system defined on multiple parts. It extends the base class LibMeshSystemVectors to provide access to vectors ghosted with both the Lagrangian partitioning (i.e., libMesh's computed partitioning, as in the base class) as well as the IB partitioning (i.e., the partitioning based on the distribution of SAMRAI data).

Detailed Description

Class LibMeshSystemIBVectors is a convenience class that manages access to libMesh vectors for the same system defined on multiple parts. It extends the base class LibMeshSystemVectors to provide access to vectors ghosted with both the Lagrangian partitioning (i.e., libMesh's computed partitioning, as in the base class) as well as the IB partitioning (i.e., the partitioning based on the distribution of SAMRAI data).

This class stores information that depends on SAMRAI's parallel partitioning: LibMeshSystemIBVectors::reinit() should be called after regridding to clear this data.

Note

This class is intended for internal use in IBAMR. It is used in IBFEMethod and IBFESurfaceMethod.

Constructor & Destructor Documentation

LibMeshSystemIBVectors() [1/2]

IBTK::LibMeshSystemIBVectors::LibMeshSystemIBVectors	(	const std::vector< IBTK::FEDataManager * > &	fe_data_managers,
		std::string	system_name
	)

Constructor.

Parameters

[in]	fe_data_managers	IBTK::FEDataManager objects for each part. These are used to get libMesh vectors with ghost regions corresponding to the Eulerian partitioning.
[in]	system_name	Name of the libMesh::System whose vectors we are accessing.

LibMeshSystemIBVectors() [2/2]

IBTK::LibMeshSystemIBVectors::LibMeshSystemIBVectors	(	const std::vector< IBTK::FEDataManager * > &	fe_data_managers,
		const std::vector< bool > &	part_mask,
		std::string	system_name
	)

Constructor, taking a mask argument indicating which systems actually exist.

Parameters

[in]	fe_data_managers	IBTK::FEDataManager objects for each part. These are used to get libMesh vectors with ghost regions corresponding to the Eulerian partitioning.
[in]	part_mask	A vector indicating on which parts the given system actually exists (for example, only some parts have fluid sources)
[in]	system_name	Name of the libMesh::System whose vectors we are accessing.

Member Function Documentation

getIBGhosted() [1/2]

std::vector< libMesh::PetscVector< double > * > IBTK::LibMeshSystemIBVectors::getIBGhosted

(

const std::string &

vec_name

)

Get, for each part, the IB-ghosted vectors corresponding to the name vec_name These vectors are ghosted with values determined by IBTK::FEDataManager (i.e., based on SAMRAI's parallel partitioning).

Note

These vectors are managed by this object: the ghosted information will not be valid after a regrid.

getIBGhosted() [2/2]

libMesh::PetscVector< double > & IBTK::LibMeshSystemIBVectors::getIBGhosted	(	const std::string &	vec_name,
		const unsigned int	part
	)

Get an IB-ghosted vector for a specific part.

Parameters

[in]	vec_name	Name of the vector.
[in]	part	Part number.

reinit()

void IBTK::LibMeshSystemIBVectors::reinit ( )

override

Reinitialize the object. This method must be called after the Eulerian data is updated.
