void DataTransferKit::ProjectionPrimitives::referenceCellCenter	(	const shards::CellTopology &	cell_topo,
		Intrepid::FieldContainer< double > &	center
	)

static

Get the center of the reference cell of the given topology.

bool DataTransferKit::ProjectionPrimitives::pointInFaceVolumeOfInfluence	(	const Teuchos::ParameterList &	parameters,
		const Intrepid::FieldContainer< double > &	point,
		const Intrepid::FieldContainer< double > &	face_nodes,
		const Intrepid::FieldContainer< double > &	face_node_normals,
		const shards::CellTopology &	face_topology
	)

static

Determine if a point is within the volume of influence of a face.

Parameters

parameters	Projection parameters.
point	Point coordinates (Dim).
face_nodes	Face node coordinates (Node,Dim).
face_node_normals	Normal vectors for each face node (Node,Dim).
face_topology	Cell topology of the face.
max_newton_iters	Maximum number of Newton iterations allowed.

	)

static

Project a point onto a face and return the physical coordinates of the projected point on that face. This requires the solution of a nonlinear parameterized projection problem.

Parameters

parameters	Projection parameters.
point	point coordinates (Dim)
face_nodes	face node coordinates (Node,Dim)
face_node_normals	face node normal vectors (Node,Dim)
face_topology	Cell topology of the face.
projected_point	Projected point in physical coordinates (Dim)
face_edge_id	The local id of the face edge onto which the node projected. Will be -1 if the node did not project onto any of the face edges.
face_node_id	The local id of the face node onto which the node projected. Will be -1 if the node did not project onto any of the face nodes.

Returns: True if the point projected onto the face.

		const Intrepid::FieldContainer< double > &	edge_1,
		const Intrepid::FieldContainer< double > &	edge_2,
		const Intrepid::FieldContainer< double > &	edge_2_node_normals,

		Intrepid::FieldContainer< double > &	edge_2_intersection,
		int &	edge_1_node_id,
		int &	edge_2_node_id
	)

static

Intersect two edges in 3 dimensions and return their intersection point realized on both edges. Return the intersection type.

Parameters

parameters	Intersection parameters.
edge_1	edge 1 node coordinates (node,dim).
edge_2	edge 2 node coordinates (node,dim).
edge_2_node_normals	edge 2 node normal vectors (node,dim).
edge_1_intersection	The coordinates of the intersection realized on the edge 1 (dim).
edge_2_intersection	The coordinates of the intersection realized on the edge 2 (dim).
edge_1_node_id	The local id of the edge 1 node onto which the edge 2 nodes projected. Will be -1 if the edge 2 did not intersect with any of the edge 1 nodes.
edge_2_node_id	The local id of the edge 2 node onto which the edge 1 nodes projected. Will be -1 if the edge 1 did not intersect with any of the edge 2 nodes.

Returns: True if there was an intersection.
