Detailed Description

This is a helper class to create libmesh elements given a MeshIterator. It will cache the elements and allow for fast O(log(n)) access to the libmesh element given the MeshElementID.

Member Function Documentation

createElement()

static libMesh::Elem * AMP::Discretization::createLibmeshElements::createElement ( const AMP::Mesh::MeshElement &  elem )

static

Create a libmesh element from an AMP element (user must deallocate)

getElement()

const libMesh::Elem * AMP::Discretization::createLibmeshElements::getElement

(

const AMP::Mesh::MeshElementID &

id

)

const

This function returns the libmesh element given a MeshElementID

Parameters

[in]

id

MeshElementID for the element of interest

getFEBase()

const libMesh::FEBase * AMP::Discretization::createLibmeshElements::getFEBase

(

const AMP::Mesh::MeshElementID &

id

)

const

This function returns the FE base given a MeshElementID

Parameters

[in]

id

MeshElementID for the element of interest

getFEType()

const libMesh::FEType * AMP::Discretization::createLibmeshElements::getFEType ( ) const

inline

This function returns the FE type used to build the elements

Definition at line 90 of file createLibmeshElements.h.

References d_type.

getQBase()

const libMesh::QBase * AMP::Discretization::createLibmeshElements::getQBase

(

const AMP::Mesh::MeshElementID &

id

)

const

This function returns the quadrature rule used to build the elements

Parameters

[in]

id

MeshElementID for the element of interest

reinit() [1/2]

void AMP::Discretization::createLibmeshElements::reinit

(

const AMP::Mesh::MeshIterator &

iterator

)

This function initializes / re-intializes the class to create the libmesh elements for all of the MeshElements in the given iterator. Note: This version only caches the libmesh elements

Parameters

[in]

iterator

MeshElementIterator containing the elements of interest

reinit() [2/2]

void AMP::Discretization::createLibmeshElements::reinit	(	const AMP::Mesh::MeshIterator &	iterator,
		libMeshEnums::QuadratureType	qtype,
		libMeshEnums::Order	qorder,
		std::shared_ptr< const libMesh::FEType >	type,
		bool	cache_fe = false
	)

This function initializes / re-intializes the class to create the libmesh elements and the FE base for all of the MeshElements in the given iterator. Note: This version caches the libmesh elements and the rule and base, reinitializing with the element. This requires more memory.

Parameters

[in]	iterator	MeshElementIterator containing the elements of interest
[in]	qtype	Type of the quadrature rule to use for the elements
[in]	qorder	Order of the quadrature rule to use for the elements
[in]	type	FE type to use for the elements
[in]	cache_fe	Do we want to cahce fe operators (true) or reinitialize the the libmesh object (false). If we cache the operators it will increase performance but significantly increase memory requirements. Note: these functions are not thread safe.
