Member Function Documentation

template<unsigned DIM>

unsigned PottsMesh< DIM >::AddElement ( PottsElement< DIM > * pNewElement )

Add an element to the mesh.

Parameters

pNewElement the new element

Returns: the index of the new element in the mesh

Definition at line 515 of file PottsMesh.cpp.

References AbstractElement< ELEMENT_DIM, SPACE_DIM >::GetIndex(), and MutableElement< DIM, DIM >::RegisterWithNodes().

template<unsigned DIM>

void PottsMesh< DIM >::Clear ( )

virtual

Delete mNodes and mElements.

Definition at line 122 of file PottsMesh.cpp.

template<unsigned DIM>

void PottsMesh< DIM >::ConstructFromMeshReader ( AbstractMeshReader< DIM, DIM > & rMeshReader )

Construct the mesh using a MeshReader.

Parameters

rMeshReader the mesh reader

Definition at line 575 of file PottsMesh.cpp.

Referenced by PottsMesh< SPACE_DIM >::load().

template<unsigned DIM>

void PottsMesh< DIM >::DeleteElement ( unsigned index )

Mark an element as deleted. Note that in a Potts mesh this does not delete the nodes so no remeshing is required.

Parameters

index the global index of a specified Potts element

Definition at line 246 of file PottsMesh.cpp.

template<unsigned DIM>

void PottsMesh< DIM >::DeleteNode ( unsigned index )

Mark a node as deleted. Note that in a Potts mesh this requires the elements and connectivity to be updated accordingley.

Parameters

index the global index of a specified node

Definition at line 274 of file PottsMesh.cpp.

template<unsigned DIM>

unsigned PottsMesh< DIM >::DivideElement	(	PottsElement< DIM > *	pElement,
		bool	placeOriginalElementBelow = `false`
	)

Divide an element by assigning half the nodes to each new element in numerical order. If an odd number of nodes then the existing element has one more node than the new element.

Parameters

pElement	the element to divide
placeOriginalElementBelow	whether to place the original element below (in the y direction) the new element (defaults to false)

Returns: the index of the new element

Not implemented in 1d

Remove the correct nodes from each element. If placeOriginalElementBelow is true, place the original element below (in the y direction or z in 3d) the new element; otherwise, place it above.

Todo:: this could be more efficient

Definition at line 388 of file PottsMesh.cpp.
