Detailed Description

Class containing mesh-to-mesh mapping information after a change in polyMesh topology.

General:

• pointMap/faceMap/cellMap:
  from current mesh back to previous mesh. (so to 'pull' the information onto the current mesh)
• reversePointMap/faceMap/cellMap:
  from previous mesh to current. (so to 'push' information)

In the topology change points/faces/cells

• can be unchanged. (faces might be renumbered though)
• can be removed (into nothing)
• can be removed into/merged with existing same entity (so point merged with other point, face with other face, cell with other cell. Note that probably only cell with cell is relevant)
• can be added from existing same 'master' entity (so point from point, face from face and cell from cell)
• can be inflated: face out of edge or point, cell out of face, edge or point.
• can be appended: added 'out of nothing'.

All this information is necessary to correctly map fields.

points

• unchanged:
  • pointMap[pointi] contains old point label
  • reversePointMap[oldPointi] contains new point label
• removed:
  • reversePointMap[oldPointi] contains -1
• merged into point:
  • reversePointMap[oldPointi] contains <-1 : -newPointi-2
  • pointMap[pointi] contains the old master point label
  • pointsFromPoints gives for pointi all the old point labels (including the old master point!)
• added-from-same:
  • pointMap[pointi] contains the old master point label
• appended:
  • pointMap[pointi] contains -1

faces

• unchanged:
  • faceMap[facei] contains old face label
  • reverseFaceMap[oldFacei] contains new face label
• removed:
  • reverseFaceMap[oldFacei] contains -1
• merged into face:
  • reverseFaceMap[oldFacei] contains <-1 : -newFacei-2
  • faceMap[facei] contains the old master face label
  • facesFromFaces gives for facei all the old face labels (including the old master face!)
• added-from-same:
  • faceMap[facei] contains the old master face label
• inflated-from-edge:
  • faceMap[facei] contains -1
  • facesFromEdges contains an entry with
    • facei
    • list of faces(*) on old mesh that connected to the old edge
• inflated-from-point:
  • faceMap[facei] contains -1
  • facesFromPoints contains an entry with
    • facei
    • list of faces(*) on old mesh that connected to the old point
• appended:
  • faceMap[facei] contains -1

Note (*)
if the newly inflated face is a boundary face the list of faces will only be boundary faces; if the new face is an internal face they will only be internal faces.

cells

• unchanged:
  • cellMap[celli] contains old cell label
  • reverseCellMap[oldCelli] contains new cell label
• removed:
  • reverseCellMap[oldCelli] contains -1
• merged into cell:
  • reverseCellMap[oldCelli] contains <-1 : -newCelli-2
  • cellMap[celli] contains the old master cell label
  • cellsFromCells gives for celli all the old cell labels (including the old master cell!)
• added-from-same:
  • cellMap[celli] contains the old master cell label
• inflated-from-face:
  • cellMap[celli] contains -1
  • cellsFromFaces contains an entry with
    • celli
    • list of cells on old mesh that connected to the old face
• inflated-from-edge:
  • cellMap[celli] contains -1
  • cellsFromEdges contains an entry with
    • celli
    • list of cells on old mesh that connected to the old edge
• inflated-from-point:
  • cellMap[celli] contains -1
  • cellsFromPoints contains an entry with
    • celli
    • list of cells on old mesh that connected to the old point
• appended:
  • cellMap[celli] contains -1
