Member Function Documentation

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
template<class Archive>
void MutableMesh< ELEMENT_DIM, SPACE_DIM >::serialize ( Archive &  archive,
const unsigned int  version 
) [inline, private]

Serialize the mesh.

Note that if you are calling this method (from subclasses) you should archive your member variables FIRST. So that this method can call a ReMesh (to convert from TrianglesMeshReader input format into your native format).

Parameters:
archive the archive
version the current version of this class

Reimplemented from TetrahedralMesh< ELEMENT_DIM, SPACE_DIM >.

Reimplemented in Cylindrical2dMesh.

void MutableMesh< ELEMENT_DIM, SPACE_DIM >::RescaleMeshFromBoundaryNode ( ChastePoint< 1 >  updatedPoint,
unsigned  boundaryNodeIndex 
)

Todo:
should unsigned GetNumBoundaryNodes() be overloaded too??
Rescale the mesh from a boundary node.

Parameters:
updatedPoint point determining the scale factor
boundaryNodeIndex index of the boundary node

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void MutableMesh< ELEMENT_DIM, SPACE_DIM >::SetNode ( unsigned  index,
ChastePoint< SPACE_DIM >  point,
bool  concreteMove = true 
) [inline, virtual]

Move the node with a particular index to a new point in space and verifies that the signed areas of the supporting Elements are positive.

Parameters:
index is the index of the node to be moved
point is the new target location of the node
concreteMove is set to false if we want to skip the signed area tests (defaults to true)

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void MutableMesh< ELEMENT_DIM, SPACE_DIM >::MoveMergeNode ( unsigned  index,
unsigned  targetIndex,
bool  concreteMove = true 
) [inline]

Move one node to another (i.e. merges the nodes), refreshing/deleting elements as appropriate.

Parameters:
index is the index of the node to be moved
targetIndex is the index of the node to move to
concreteMove can be set to false if you just want to check whether this will work (defaults to true). Set it to true if you're doing the merger for real, in order to do all the bookkeeping.

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void MutableMesh< ELEMENT_DIM, SPACE_DIM >::DeleteNode ( unsigned  index  )  [inline]

Delete a node from the mesh by finding an appropriate neighbour node to merge it with.

Parameters:
index is the index of the node to be deleted

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void MutableMesh< ELEMENT_DIM, SPACE_DIM >::DeleteNodePriorToReMesh ( unsigned  index  )  [inline]

Mark a node as deleted. Note that this method DOES NOT deal with the associated elements and therefore should only be called immediately prior to a ReMesh() being called. (Thus saves work compared to DeleteNode() function and does not MoveMerge the node and elements).

Parameters:
index The index of the node to delete

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
void MutableMesh< ELEMENT_DIM, SPACE_DIM >::DeleteBoundaryNodeAt ( unsigned  index  )  [inline]

Remove a boundary node, and update all the appropriate data structures.

The deleted node is not removed from the list, merely marked as deleted, and can be reused when a new node is added to the mesh.

Any elements or boundary elements containing this node will be removed. The boundary nodes information will be updated with new boundary node(s). NB: New boundary elements WILL NOT be added.

Parameters:
index The index of the node to remove.

bool MutableMesh< ELEMENT_DIM, SPACE_DIM >::CheckIsVoronoi ( double  maxPenetration = 0.0  )  [inline]

Checks the entire mesh element by element and checks whether any neighbouring node is inside the circumsphere of this element.

Parameters:
maxPenetration is the maximum distance a node is allowed to be inside the circumsphere of an element that it is not a member of, as a proportion of the circumsphere radius.

Todo:
use ElementIterator here?
