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

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.

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
