Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >

A mutable vertex-based mesh class, which inherits from VertexMesh and allows for local remeshing. This is implemented through simple operations including node merging, neighbour exchange ("T1 swap"), node/edge merging in the case of intersections ("T3 swap") and removal of small triangular elements ("T2 swap").

MutableVertexMesh is used as a member of the VertexBasedCellPopulation class to represent the junctional network of cells that forms the basis of simulations of off-lattice vertex-based models.

Member Function Documentation

◆ AddElement()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

unsigned MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >::AddElement ( VertexElement< ELEMENT_DIM, SPACE_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 384 of file MutableVertexMesh.cpp.

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

◆ AddNode()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

unsigned MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >::AddNode ( Node< SPACE_DIM > * pNewNode )

Add a node to the mesh.

Note: After calling this one or more times, you must then call ReMesh.

Parameters

pNewNode pointer to the new node

Returns: the global index of the new node in the mesh.

◆ CheckForIntersections()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

bool MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >::CheckForIntersections ( )

protected

Helper method for ReMesh().

Check if any elements have become intersected and correct this by implementing the appropriate local remeshing operation (a T3 swap or node merge).

Returns: whether to recheck the mesh again

Definition at line 1151 of file MutableVertexMesh.cpp.

References AbstractElement< ELEMENT_DIM, SPACE_DIM >::GetNodeGlobalIndex(), AbstractElement< ELEMENT_DIM, SPACE_DIM >::GetNumNodes(), and NEVER_REACHED.

◆ CheckForRosettes()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

void MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >::CheckForRosettes ( )

private

Helper method for ReMesh().

Check whether the mesh contains rosettes or protorosettes, and implement resolution events if necessary.

First, we loop over each node and populate vectors of protorosette and rosette nodes which need to undergo resolution.

We do not perform the resolution events in this initial loop because the resolution events involve changing nodes in the mesh.

Finally, we loop over the contents of each node vector and perform the necessary resolution events.

Because each resolution event changes nodes, we include several assertions to catch possible unconsidered behaviour.

Definition at line 4033 of file MutableVertexMesh.cpp.

References RandomNumberGenerator::Instance(), Node< SPACE_DIM >::IsDeleted(), NEVER_REACHED, and Node< SPACE_DIM >::rGetContainingElementIndices().

◆ CheckForSwapsFromShortEdges()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

bool MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >::CheckForSwapsFromShortEdges ( )

protectedvirtual

Helper method for ReMesh().

Check if any neighbouring nodes in an element are closer than the mCellRearrangementThreshold and are not contained in any triangular elements. If any such pair of nodes are found, then call IdentifySwapType(), which in turn implements the appropriate local remeshing operation (a T1 swap, void removal, or node merge).

Returns: whether we need to check for, and implement, any further local remeshing operations (true if any swaps are performed).

Todo:: Could we search more efficiently by just iterating over edges? (see #2401)

Todo:: Use iterators to tidy this up (see #2401)

◆ CheckForT2Swaps()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

bool MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >::CheckForT2Swaps ( VertexElementMap & rElementMap )

Helper method for ReMesh().

Check for any triangular element whose area is smaller than mT2Threshold and call PerformT2Swap() on any such element.

Parameters

rElementMap a VertexElementMap which associates the indices of VertexElements in the old mesh with indices of VertexElements in the new mesh. This should be created with the correct size, GetNumElements()

Returns: whether we need to check for, and implement, any further local remeshing operations

Helper method for ReMesh(), called by IdentifySwapType().

Handles the case where a swap involves a junction with more than three adjacent elements. This is implemented in a separate method to allow child classes to override this behaviour and implement junction remodelling with high-order nodes (see #2664).

protectedvirtual

Helper method for ReMesh(), called by CheckForSwapsFromShortEdges() when neighbouring nodes in an element have been found to be closer than the mCellRearrangementThreshold and do not share any triangular elements.

Identify the type of local remeshing operation required (T1 swap, void removal, or node merge).

Parameters

pNodeA	one of the nodes to perform the swap with
pNodeB	the other node to perform the swap

Here, the triangular element would be along the short edge. Since we are already checking in CheckForSwapsFromShortEdges() whether the element is triangular, this exception is redundant for simulations. We leave it in for clarity. ///

Todo:: : consider removing the checking for this exception (see #2401)

If this is true then one of the elements adjacent to the triangular void is triangular. This element will then not share the short edge that is considered for a swap. Nevertheless, it would loose an edge during the swap. We are currently not able to deal with this situation. Related to #2533 and #2401.

◆ PerformProtorosetteResolution()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

void MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >::PerformProtorosetteResolution ( Node< SPACE_DIM > * pProtorosetteNode )

private

Helper method for ReMesh(), called by CheckForRosettes().

Split protorosette in random direction. Create new node and redistribute nodes along line joining centres of randomly selected cell and cell opposite it.

Parameters

pProtorosetteNode node at centre of protorosette

Ordering elements as follows:

\ A / \ / \ / B X D / \ / \ / C \

Element A is the randomly chosen element. Element C, which is directly opposite A, will end up separated from A, while the two elements B and D which start adjacent to A will end up sharing a common edge:

\ A / \ / \ / | B | D | / \ / \ / C \

Next, we compute where to place the two nodes which will replace the single protorosette node.

We place each node along the line joining the protorosette node to the centroid of element which will contain it, and the distance along this line is half of the swap distance.

To do this, we will move the existing protorosette node in to element A, and create a new node in element C. We then need to tidy up the nodes by adding the new node to elements B, C and D, and removing the protorosette node from element C.

NOTE: as the protorosette node was not necessarily on the line joining the centroids of elements A and C, unlike in a T1 swap, the new node locations will not necessarily be the full swap distance apart.

Here, we add the new node to elements B, C and D.

The method AddNode() takes the local index of a node i, where the new node is to be inserted between nodes i and i+1, so we need to find the local idx of the node directly before (clockwise from) where we wish to insert it.

For elements C and D, we just need the local index of the protorosette node, but for element B we need the one before, modulo number of elements.

◆ PerformRosetteRankDecrease()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

void MutableVertexMesh< ELEMENT_DIM, SPACE_DIM >::PerformRosetteRankDecrease ( Node< SPACE_DIM > * pRosetteNode )

private

Helper method for ReMesh(), called by CheckForRosettes().

Split rosette by removing one cell at random. Create new node positioned along line joining rosette node and centre of randomly selected cell. Rosette node will remain unmoved.

Parameters

pRosetteNode node at centre of rosette

We have now picked a vertex element at random from the rosette. This element will now be disconnected from the rosette in a manner analogous to performing a T1 swap.

The node at the centre of the rosette will not move, and a new node will be created a suitable distance away, along a line joining the rosette node and the centroid of the element we have randomly selected to move.

Ordering of elements is as follows:

\ S / \ / N \ / P —–X—– / \ / \ / \

where element S is the selected element, N is the next (counterclockwise) element from S, and P is the previous (clockwise) element from S.

Elements N and P will end up sharing an edge:

\ S / \ / \ / N | P | —–*—– / \ / \ / \

Next, we compute where to place the new node which will separate the rosette node from element S.

We place this node along the line joining the rosette node to the centroid of element S, at a distance of the swap distance ( (rearrangement ratio) x (rearrangement threshold) )

To do this, we create a new node in element S. We then need to tidy up the nodes by adding the new node to elements S, N and P, and by removing the rosette node from element S.

Here, we add the new node to elements S, N and P, and remove the rosette node from element S.

The method AddNode() takes the local index of a node i, where the new node is to be inserted between nodes i and i+1, so we need to find the local idx of the node directly before (clockwise from) where we wish to insert it.

For elements S and P, we just need the local index of the rosette node, but for element N we need the one before, modulo number of elements.

	)

private

Helper method for ReMesh(), called by HandleHighOrderJunctions().

Merge a node of a non-rosette cell with the central node of a rosette, by replacing the node in the non-rosette cell with that of the rosette centre, keeping the rosette centre in the same position.

Parameters

pNodeA	one of the nodes to perform the merge with
pNodeB	the other node to perform the merge with

The picture below shows the situation we are in. The central node (marked with an 'X') is contained in (at least) four elements already (A, B, C and D), and this is the rosette node which we have designated as hi_rank_node.

The node shared by elements C, D and E has come within the cell rearrangement threshold of the rosette node in order for this method to have been called. We have designated this node lo_rank_node.

We now 'merge' hi_rank_node and lo_rank_node, but keep hi_rank_node where it is (which is why we don't call PerformNodeMerge(), as that would move both nodes to their average location).

To accomplish this merge, we need do nothing to elements A and B. We remove lo_rank_node from elements C and D, and we replace lo_rank_node by hi_rank_node in element E.

		unsigned	indexB,

	)

private

Helper method for ReMesh(), called by PerformT3Swap(). During T3 swaps nodes are merged onto edges. This method checks if the edge is too short and moves its vertices apart if necessary in order to prevent T1 swaps from happening right away. The method also checks that the location where the merged node is going to end up at is not too close to one of the neighbouring vertices and moves it if necessary to prevent T1 swaps.

Parameters

indexA	index of one of the nodes on the short edge
indexB	index of the other node on the short edge
intersection	the intersection location, i.e. the location where we are planning to put the merged node

Returns: intersection, the corrected location of where we are planning to put the merged node

If the edge is shorter than 4.0*mCellRearrangementRatio*mCellRearrangementThreshold move vertexA and vertexB 4.0*mCellRearrangementRatio*mCellRearrangementThreshold apart.

Todo:: investigate if moving A and B causes other issues with nearby nodes (see #2401)

Note: this distance is so that there is always enough room for new nodes (if necessary)

Todo:: currently this assumes a worst case scenario of 3 nodes between A and B could be less movement for other cases (see #1399 and #2401)

Reset the intersection away from vertices A and B to allow enough room for new nodes.

If the intersection is within mCellRearrangementRatio^2*mCellRearrangementThreshold of vertexA or vertexB move it mCellRearrangementRatio^2*mCellRearrangementThreshold away.

Note: this distance so that there is always enough room for new nodes (if necessary).
