Detailed Description

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

A vertex-based mesh class, in which elements may contain different numbers of nodes. This is facilitated by the VertexElement class.

This class has two applications in the cell_based code.

First, VertexMesh is used as a member of the MeshBasedCellPopulation class to represent a Voronoi tessellation, the dual to a Delaunay mesh, which allows the shapes of cells to be visualised in simulations of a class of off-lattice cell centre-based models.

Second, VertexMesh serves as a parent class for MutableVertexMesh, which 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.

Alternative 2D 'Voronoi' constructor.

This VertexMesh constructor is currently only defined for 2D meshes.

isBounded	a boolean to indicate whether to bound the voronoi tesselation. Defaults to false.
scaleBoundByEdgeLength	whether to scale the distance bounding nodes are placed from the mesh. Defaults to true.
maxDelaunayEdgeLength	the maximum edge length in the mesh. Edges longer than this are ignored in boundary calculation. Defaults to DBL_MAX so there ia no max length.

◆ CalculateAreaOfFace()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

double VertexMesh< ELEMENT_DIM, SPACE_DIM >::CalculateAreaOfFace ( VertexElement< ELEMENT_DIM - 1, SPACE_DIM > * pFace )

virtual

Get the area of a given face in 3D. Uses CalculateUnitNormalToFaceWithArea

This needs to be overridden in daughter classes for non-Euclidean metrics.

Parameters

pFace a face in the mesh

Returns: the area

Definition at line 1814 of file VertexMesh.cpp.

References NEVER_REACHED.

◆ CalculateMomentsOfElement()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

c_vector< double, 3 > VertexMesh< ELEMENT_DIM, SPACE_DIM >::CalculateMomentsOfElement ( unsigned index )

virtual

Compute the second moments and product moment of area for a given 2D element about its centroid. These are:

I_xx, the second moment of area about an axis through the centroid of the element parallel to the x-axis;

I_yy, the second moment of area about an axis through the centroid of the element parallel to the y-axis;

and I_xy, product moment of area through the centroid of the element.

Formulae for these quantities may be found e.g. in the following reference:

Mechanics of Materials James M. Gere (Author), Barry J. Goodno. Cengage Learning; 8th edition (January 1, 2012)

This method is used within GetShortAxisOfElement() to compute the direction of the shortest principal axis passing through the centroid, or 'short axis', of the element.

Note that by definition, the second moments of area must be non-negative, while the product moment of area may not be.

Parameters

index the global index of a specified vertex element

Returns: (Ixx,Iyy,Ixy).

double VertexMesh< ELEMENT_DIM, SPACE_DIM >::CalculateUnitNormalToFaceWithArea	(	VertexElement< ELEMENT_DIM - 1, SPACE_DIM > *	pFace,
		c_vector< double, SPACE_DIM > &	rNormal
	)

Compute the unit normal vector to a given face in 3D. This is achieved by calculating scaled normal, which is the effective sum of signed areas of triangle forming the face. Note: this may return the outward or inward normal, depending on the face chirality.

Parameters

pFace	a face in the mesh
rNormal	vector in which to return the unit normal

Returns: the area

◆ ConstructFromMeshReader()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

◆ ElementIncludesPoint()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

bool VertexMesh< ELEMENT_DIM, SPACE_DIM >::ElementIncludesPoint	(	const c_vector< double, SPACE_DIM > &	rTestPoint,
		unsigned	elementIndex
	)

protected

Test whether a given point lies inside a given element.

We use a winding number test, which counts the number of times the polygon associated with the element winds around the given point. The point is outside only when this "winding number" vanishes; otherwise, the point is inside.

One must decide whether a point on the polygon's boundary is inside or outside: we adopt the standard convention that a point on a left or bottom edge is inside, and a point on a right or top edge is outside. This way, if two distinct polygons share a common boundary segment, then a point on that segment will be in one polygon or the other, but not both at the same time.

Parameters

rTestPoint	the point to test
elementIndex	global index of the element in the mesh

Returns: if the point is included in the element.

◆ GetPerimeterGradientOfElementAtNode()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

c_vector< double, SPACE_DIM > VertexMesh< ELEMENT_DIM, SPACE_DIM >::GetPerimeterGradientOfElementAtNode	(	VertexElement< ELEMENT_DIM, SPACE_DIM > *	pElement,
		unsigned	localIndex
	)

Compute the gradient of the perimeter of a 2D element at its nodes. This returns the sum of GetPreviousEdgeGradientAtNode() and GetNextEdgeGradientAtNode().

Parameters

pElement	pointer to a specified vertex element
localIndex	local index of a node in this element

Returns: the gradient of the perimeter of the element, evaluated at this node.

◆ GetPreviousEdgeGradientOfElementAtNode()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

c_vector< double, SPACE_DIM > VertexMesh< ELEMENT_DIM, SPACE_DIM >::GetPreviousEdgeGradientOfElementAtNode	(	VertexElement< ELEMENT_DIM, SPACE_DIM > *	pElement,
		unsigned	localIndex
	)

Compute the gradient of the edge of a 2D element ending at its nodes.

N.B. This calls GetVectorFromAtoB(), which can be overridden in daughter classes for non-Euclidean metrics.

Parameters

pElement	pointer to a specified vertex element
localIndex	local index of a node in this element

Returns: the gradient of the edge of the element that ends at this node.

◆ GetRosetteRankOfElement()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

unsigned VertexMesh< ELEMENT_DIM, SPACE_DIM >::GetRosetteRankOfElement ( unsigned index )

This is defined as the maximum number of elements shared by any node in the specified element.

Parameters

index the global index of a specified vertex element

Returns: the rosette rank of the element

◆ GetShortAxisOfElement()

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>

c_vector< double, SPACE_DIM > VertexMesh< ELEMENT_DIM, SPACE_DIM >::GetShortAxisOfElement ( unsigned index )

Compute the direction of the shortest principal axis passing through the centroid, or 'short axis', of a given element. This is the eigenvector associated with the eigenvalue of largest magnitude of the inertia matrix

J = ( I_xx -I_xy ) ( -I_xy I_yy )

whose entries are computed by calling the method CalculateMomentsOfElement().

Note that if the nodes owned by the element are supplied in clockwise rather than anticlockwise manner, or if this arises when any periodicity is enforced, then the sign of each moment may be incorrect change. This means that we need to consider the eigenvalue of largest magnitude rather than largest value when computing the short axis of the element.

If the element is a regular polygon then the eigenvalues of the inertia tensor are equal: in this case we return a random unit vector.

This method is only implemented in 2D at present.

Parameters

index the global index of a specified vertex element

Returns: a unit vector giving the direction of the short axis

	)

virtual

Overridden GetVectorFromAtoB() method. Returns a vector between two points in space.

If the mesh is being used to represent a Voronoi tessellation, and mpDelaunayMesh is not NULL, then use that to compute GetVectorFromAtoB.
