Member Function Documentation

◆ AddElement()

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

Add an element to the mesh.

Parameters
pNewElementthe new element
Returns
the index of the new element in the mesh

Definition at line 513 of file PottsMesh.cpp.

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

◆ Clear()

template<unsigned DIM>
void PottsMesh< DIM >::Clear ( )
virtual

Delete mNodes and mElements.

Definition at line 120 of file PottsMesh.cpp.

◆ ConstructFromMeshReader()

◆ DeleteElement()

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
indexthe global index of a specified Potts element

Definition at line 245 of file PottsMesh.cpp.

◆ DeleteNode()

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 accordingly.

Parameters
indexthe global index of a specified node

Definition at line 272 of file PottsMesh.cpp.

◆ DivideElement()

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
pElementthe element to divide
placeOriginalElementBelowwhether 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 386 of file PottsMesh.cpp.

This should probably be returning the nearest node

Definition at line 169 of file PottsMesh.cpp.
