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
