◆ checkOrientation()

bool checkOrientation	(	const PrimitivePatch< FaceList, PointField > &	p,
		const bool	report = `false`,
		labelHashSet *	marked = `0`
	)

static

Check for orientation issues.

Returns true if problems were found. If a normal flips across an edge, places it in the HashSet

Compute normal from 3 points, use the first as the origin

minor warpage should not be a problem

		const BoolListType &	borderEdge,
		const label	facei,
		const label	currentZone,
		labelList &	faceZone
	)

static

Fill faceZone with currentZone for every face reachable.

from facei without crossing edge marked in borderEdge. Note: faceZone has to be sized nFaces before calling.

◆ markZones() [1/2]

static label markZones	(	const PrimitivePatch< FaceList, PointField > &	,

	)

static

Size and fills faceZone with zone of face.

Zone is area reachable by edge crossing without crossing borderEdge. Returns number of zones.

	)

static

Determine the mapping for a sub-patch.

Only include faces for which bool-list entry is true.

[in]	p	patch to be searched on
[in]	includeFaces	faces to include
[out]	pointMap	mapping new to old localPoints
[out]	faceMap	mapping new to old faces

◆ sortedEdgeFaces() [1/2]

static labelListList sortedEdgeFaces ( const PrimitivePatch< FaceList, PointField > & )

static

Return edge-face addressing sorted by angle around the edge.

Orientation is anticlockwise looking from edge.vec(localPoints())

◆ sortedPointEdges() [1/2]

static labelListList sortedPointEdges ( const PrimitivePatch< FaceList, PointField > & )

static

Return point-edge addressing sorted by order around the point.

◆ edgeOwner() [1/2]

static labelList edgeOwner ( const PrimitivePatch< FaceList, PointField > & )

static

If 2 face neighbours: label of face where ordering of edge.

is consistent with righthand walk. If 1 neighbour: label of only face. If >2 neighbours: undetermined.

static

Find corresponding points on patches sharing the same points.

p1PointLabels : points on p1 that were matched p2PointLabels : corresponding points on p2

static

Gather (mesh!) points and faces onto master and merge collocated.

points into a single patch. Uses coupled point mesh structure so does not need tolerances. On master and slave returns:

pointToGlobal : for every local point index the global point index
uniqueMeshPointLabels : my local mesh points
globalPoints : global numbering for the global points
globalFaces : global numbering for the faces On master only:
mergedFaces : the merged faces
mergedPoints : the merged points
