def FindCoincidentFreeBorders	(	self,

	)

Sew FreeBorder's of each group.

Parameters

freeBorders	either a SMESH.CoincidentFreeBorders structure or a list of lists where each enclosed list contains node IDs of a group of coincident free borders such that each consequent triple of IDs within a group describes a free border in a usual way: n1, n2, nLast - i.e. 1st node, 2nd node and last node of a border. For example [[1, 2, 10, 20, 21, 40], [11, 12, 15, 55, 54, 41]] describes two groups of coincident free borders, each group including two borders.
createPolygons	if `True` faces adjacent to free borders are converted to polygons if a node of opposite border falls on a face edge, else such faces are split into several ones.
createPolyhedra	if `True` volumes adjacent to free borders are converted to polyhedra if a node of opposite border falls on a volume edge, else such volumes, if any, remain intact and the mesh becomes non-conformal.

Returns: a number of successfully sewed groups

		NodeID2OfSide1ToMerge,
		NodeID2OfSide2ToMerge
	)

Sew two sides of a mesh.

The nodes belonging to Side1 are merged with the nodes of elements of Side2. The number of elements in theSide1 and in theSide2 must be equal and they should have similar nodal connectivity. The nodes to merge should belong to side borders and the first node should be linked to the second.

Returns: SMESH::Sew_Error
