24 Class
25  Foam::mapPolyMesh
26 
27 Description
28  Class containing mesh-to-mesh mapping information after a change
29  in polyMesh topology.
30 
31  General:
32  - pointMap/faceMap/cellMap: \n
33  from current mesh back to previous mesh.
34  (so to 'pull' the information onto the current mesh)
35  - reversePointMap/faceMap/cellMap: \n
36  from previous mesh to current. (so to 'push' information)
37 
38  In the topology change points/faces/cells
39  - can be unchanged. (faces might be renumbered though)
40  - can be removed (into nothing)
41  - can be removed into/merged with existing same entity
42  (so point merged with other point, face with other face, cell with
43  other cell. Note that probably only cell with cell is relevant)
44  - can be added from existing same 'master' entity
45  (so point from point, face from face and cell from cell)
46  - can be inflated: face out of edge or point,
47  cell out of face, edge or point.
48  - can be appended: added 'out of nothing'.
49 
50  All this information is necessary to correctly map fields.
51 
52  \par points
53 
54  - unchanged:
55  - pointMap[pointi] contains old point label
56  - reversePointMap[oldPointi] contains new point label
57  - removed:
58  - reversePointMap[oldPointi] contains -1
59  - merged into point:
60  - reversePointMap[oldPointi] contains <-1 : -newPointi-2
61  - pointMap[pointi] contains the old master point label
62  - pointsFromPoints gives for pointi all the old point labels
63  (including the old master point!)
64  - added-from-same:
65  - pointMap[pointi] contains the old master point label
66  - appended:
67  - pointMap[pointi] contains -1
68 
69  \par faces
70 
71  - unchanged:
72  - faceMap[facei] contains old face label
73  - reverseFaceMap[oldFacei] contains new face label
74  - removed:
75  - reverseFaceMap[oldFacei] contains -1
76  - merged into face:
77  - reverseFaceMap[oldFacei] contains <-1 : -newFacei-2
78  - faceMap[facei] contains the old master face label
79  - facesFromFaces gives for facei all the old face labels
80  (including the old master face!)
81  - added-from-same:
82  - faceMap[facei] contains the old master face label
83  - inflated-from-edge:
84  - faceMap[facei] contains -1
85  - facesFromEdges contains an entry with
86  - facei
87  - list of faces(*) on old mesh that connected to the old edge
88  - inflated-from-point:
89  - faceMap[facei] contains -1
90  - facesFromPoints contains an entry with
91  - facei
92  - list of faces(*) on old mesh that connected to the old point
93  - appended:
94  - faceMap[facei] contains -1
95 
96  Note (*) \n
97  if the newly inflated face is a boundary face the list of faces will
98  only be boundary faces; if the new face is an internal face they
99  will only be internal faces.
100 
101  \par cells
102 
103  - unchanged:
104  - cellMap[celli] contains old cell label
105  - reverseCellMap[oldCelli] contains new cell label
106  - removed:
107  - reverseCellMap[oldCelli] contains -1
108  - merged into cell:
109  - reverseCellMap[oldCelli] contains <-1 : -newCelli-2
110  - cellMap[celli] contains the old master cell label
111  - cellsFromCells gives for celli all the old cell labels
112  (including the old master cell!)
113  - added-from-same:
114  - cellMap[celli] contains the old master cell label
115  - inflated-from-face:
116  - cellMap[celli] contains -1
117  - cellsFromFaces contains an entry with
118  - celli
119  - list of cells on old mesh that connected to the old face
120  - inflated-from-edge:
121  - cellMap[celli] contains -1
122  - cellsFromEdges contains an entry with
123  - celli
124  - list of cells on old mesh that connected to the old edge
125  - inflated-from-point:
126  - cellMap[celli] contains -1
127  - cellsFromPoints contains an entry with
128  - celli
129  - list of cells on old mesh that connected to the old point
130  - appended:
131  - cellMap[celli] contains -1
