◆ addUpCell()

void SMDS_Down2D::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 from SMDS_Downward.

◆ allocate()

void SMDS_Down2D::allocate ( int nbElems )

protectedvirtual

Resize the downward connectivity storage vector if needed.

Parameters

nbElems total number of elements of the same type required

Implements SMDS_Downward.

◆ compactStorage()

void SMDS_Down2D::compactStorage ( )

protectedvirtual

Implements SMDS_Downward.

◆ computeEdgesWithNodes()

		ListElemByNodesType &	facesWithNodes
	)

◆ computeVolumeIds() [1/2]

int SMDS_Down2D::computeVolumeIds	(	ElemByNodesType &	faceByNodes,
		int *	ids
	)

protected

Find in vtkUnstructuredGrid the volumes containing a face described by it's nodes Search the volumes containing a face, to store the info in SMDS_Down2D for later uses with SMDS_Down2D::getUpCells and SMDS_Down2D::getUpTypes. A face belongs to 0, 1 or 2 volumes, identified by their id in vtkUnstructuredGrid.

Parameters

faceByNodes
ids	a couple of vtkId, initialized at -1 (no parent volume)

Returns: number of volumes (0, 1 or 2)

◆ computeVolumeIds() [2/2]

int SMDS_Down2D::computeVolumeIds	(	int	cellId,
		int *	ids
	)

protected

Find in vtkUnstructuredGrid the volumes containing a face already stored in vtkUnstructuredGrid. Search the volumes containing a face, to store the info in SMDS_Down2D for later uses with SMDS_Down2D::getUpCells and SMDS_Down2D::getUpTypes. A face belongs to 0, 1 or 2 volumes, identified by their id in vtkUnstructuredGrid.

Parameters

cellId	the face cell id in vkUnstructuredGrid
ids	a couple of vtkId, initialized at -1 (no parent volume)

Returns: number of volumes (0, 1 or 2)
