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 nessecary 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
