Constructor & Destructor Documentation

SMDS_Downward::SMDS_Downward	(	SMDS_UnstructuredGrid *	grid,
		int	nbDownCells
	)

protected

Generic constructor for all the downward connectivity structures (one per vtk cell type).

The static structure for cell dimension is set only once.

Parameters

grid	unstructured grid associated to the mesh.
nbDownCells	number of downward entities associated to this vtk type of cell.

Returns

References _cellDimension, _cellIds, _cellTypes, _maxId, and getCellDimension().

Member Function Documentation

int SMDS_Downward::addCell ( int vtkId = -1 )

protected

Give or create an entry for downward connectivity structure relative to a cell.

If the entry already exists, just return its id, otherwise, create it. The internal storage memory is allocated if needed. The SMDS_UnstructuredGrid::_cellIdToDownId vector is completed for vtkUnstructuredGrid cells.

Parameters

vtkId for a vtkUnstructuredGrid cell or -1 (default) for a created downward cell.

Returns: the rank in downward[vtkType] structure.

void SMDS_Downward::addDownCell	(	int	cellId,
		int	lowCellId,
		unsigned char	aType
	)

protectedvirtual

Id's are downward connectivity id's.

add a downward entity of dimension n-1 (cell or node) to a given cell.

Actual implementation is done in derived methods.

Parameters

cellId	index of the parent cell (dimension n) in the downward structure relative to a vtk cell type.
lowCellId	index of the children cell to add (dimension n-1)
aType	vtk cell type of the cell to add (needed to find the SMDS_Downward structure containing the cell to add).

Reimplemented in SMDS_DownQuadHexa, SMDS_DownHexa, SMDS_DownQuadPenta, SMDS_DownPenta, SMDS_DownQuadPyramid, SMDS_DownPyramid, SMDS_DownQuadTetra, SMDS_DownTetra, SMDS_DownQuadQuadrangle, SMDS_DownQuadrangle, SMDS_DownQuadTriangle, and SMDS_DownTriangle.

void SMDS_Downward::addUpCell	(	int	cellId,
		int	upCellId,
		unsigned char	aType
	)

protectedvirtual

Id's are downward connectivity id's.

add a downward entity of dimension n+1 to a given cell.

Actual implementation is done in derived methods.

Parameters

cellId	index of the children cell (dimension n) in the downward structure relative to a vtk cell type.
upCellId	index of the parent cell to add (dimension n+1)
aType	vtk cell type of the cell to add (needed to find the SMDS_Downward structure containing the cell to add).

Reimplemented in SMDS_Down2D, and SMDS_Down1D.

See Also: SMDS_Downward::getNumberOfDownCells for the number of downward entities.; SMDS_Downward::getDownTypes for the vtk cell types associated to the downward entities.

Parameters

cellId index of the cell in the downward structure relative to a given vtk cell type.
