Detailed Description

Unstructured volume mesh template.

Header file to be completed including all required classes to define an unstructured volume mesh with its associated scalar and vector sets.

Intended to help implement simple mesh. Just fill up the empty methods of the following classes (search for YOUR CODE HERE):

• MyVolumeCell : volume cell template.
• MyVolumeTopologyExplicitI : volume topology template.
• MyGeometryI : geometry template.
• MyScalarSetI : scalar set template.
• MyVectorSetI : vector set template.

Hint: some should inherit both from MeshViz interfaces and the user's application data classes.

Note:

Nonmandatory methods are marked as optional.

For advanced implementations, refer to the MiVolumeMeshUnstructured interface. Class defining a volume cell of the mesh

size_t MyVolumeCell::appendLocalNodesIndexOfFacet	(	size_t	facet,
		std::vector< size_t > &	facetNodes
	)			const [inline, virtual]

Appends the array of local node indices belonging to a given facet to facetNodes.

Parameters:

[in]	facet	The index of the facet (where 0 <= facet < getNumFacets()).
	facetNodes	A vector in which the local node indices of the facet will be appended.

Returns:

the number of nodes added.

Reimplemented from MiVolumeCell.

size_t MyVolumeCell::appendNodesIndexOfFacet	(	size_t	facet,
		std::vector< size_t > &	facetNodes
	)			const [inline, virtual]

Appends the array of node indices belonging to a given facet to facetNode.

Parameters:

[in]	facet	The index of the facet (where 0 <= facet < getNumFacets()).
	facetNodes	A vector in which the node indices of the facet will be appended.

Returns:

the number of nodes appended in facetNodes.

Implements MiVolumeCell.

void MyVolumeCell::getIsosurfTopology	(	unsigned char	caseId,
		std::vector< std::pair< size_t, size_t > > &	edgeList
	)			const [inline, virtual]

Gets the list of topological polygons defining the part of the isosurface topology in this cell.

Implements MiVolumeCell.

size_t MyVolumeCell::getNodeIndex

(

size_t

node

)

const [inline, virtual]

Gets the index (in the mesh) of a node.

Parameters:

[in]

node

Node number (where: 0 <= node < getNumNodes()).

Implements MiCell.

size_t MyVolumeCell::getNumFacets

(

)

const [inline, virtual]

Gets the number of facets.

Implements MiVolumeCell.

size_t MyVolumeCell::getNumNodes

(

)

const [inline, virtual]

Gets the number of nodes.

Implements MiCell.

double MyVolumeCell::getRelativeSize

(

const MiGeometryI *

meshGeometry

)

const [inline, virtual]

Gets the relative size of the cell.

Parameters:

[in]

meshGeometry

the geometry of the mesh. Used to retrieve the node coordinates of this cell.

Reimplemented from MiCell.

bool MyVolumeCell::isPointInsideCell	(	const MiGeometryI &	meshGeometry,
		const MbVec3d &	point,
		std::vector< double > &	weights
	)			const [inline, virtual]

Checks if a point is inside or outside a cell.

Parameters:

[in]	meshGeometry	The geometry of the mesh. Used to retrieve the node coordinates of this cell.
[in]	point	The point to be checked.
[out]	weights	containing at least as many elements as the number of nodes in this cell.

Returns:

True if the point is inside the cell.

Reimplemented from MiCell.
