Detailed Description

This class extends vtkUnstructuredGrid to deal with downward connectivity.

Use method BuildDownwardConnectivity to build downward connectivity and CleanDownwardConnectivity() to clean it. The downward connectivity takes up a lot of memory, so, build it only when necessary and clean after usage.

Downward connectivity is no more valid if vtkUnstructuredGrid is modified.

Built downward connectivity is kept in std::vector<SMDS_Downward*> _downArray; Vector item #i stores connectivity of all elements of VTK type i.

As vtkUnstructuredGrid has elements and nodes numbering different from the SMDS one, here are the methods to convert IDs between VTK and SMDS:

vtkId -> smId (nodes and elements) smIdType SMDS_Mesh::FromVtkToSmds(vtkIdType)
smId -> vtkId (elements) SMDS_MeshElement* SMDS_Mesh::FindElement(smIdType) vtkIdType SMDS_MeshElement::GetVtkID()
smId -> vtkId (nodes) SMDS_MeshNode* SMDS_Mesh::FindNode(smIdType) vtkId = SMDS_MeshElement::GetVtkID()

And here are the way to convert between VTK IDs and downward connectivity indices:

vtkId -> downId + vtkType int SMDS_UnstructuredGrid::CellIdToDownId(vtkIdType) int vtkUnstructuredGrid::GetCellType(vtkIdType)
(downId + vtkType) -> vtkId SMDS_Downward* SMDS_UnstructuredGrid::getDownArray(unsigned char vtkType) int SMDS_Downward::getVtkCellId(int downId) Not all elements of downward connectivity can have corresponding VTK cells. -1 will be returned if there is no VTK cell.

		std::map< int, std::map< long, int > > &	nodeQuadDomains
	)

Create a volume (prism or hexahedron) by duplication of a face.

Designed for use in creation of flat elements separating volume domains. A face separating two domains is shared by two volume cells. All the nodes are already created (for the two faces). Each original Node is associated to corresponding nodes in the domains. Some nodes may be duplicated for more than two domains, when domain separations intersect. In that case, even some of the nodes to use for the original face may be changed.

Parameters

vtkVolId	vtk id of a volume containing the face, to get an orientation for the face.
domain1	domain of the original face
domain2	domain of the duplicated face
originalNodes	the vtk node ids of the original face
nodeDomains	map(original id --> map(domain --> duplicated node id))

Returns: ok if success.

Get the neighbors of a cell.

Parameters

neighborsVtkIds	vector of neighbors vtk id's to fill (reserve enough space).
downIds	downward id's of cells of dimension n-1, to fill (reserve enough space).
downTypes	vtk types of cells of dimension n-1, to fill (reserve enough space).
vtkId	the vtk id of the cell
