25  Foam::addPatchCellLayer
26 
27 Description
28  Adds layers of cells to outside of polyPatch. Can optionally create
29  stand-alone extruded mesh (addToMesh=false).
30 
31  Call setRefinement with offset vector for every patch point and number
32  of layers per patch face and number of layers per patch point.
33  - offset vector should be zero for any non-manifold point and synchronised
34  on coupled points before calling this.
35  - offset vector of zero will not add any points.
36  - gets supplied the number of extruded layers both per face and per
37  point. Usually the point nlayers is the max of surrounding face nlayers.
38 
39  point nlayers:
40  - 0 : no extrusion. Any surrounding face being extruded becomes 'prism'
41  - >0 : should be max of surrounding face nlayers.
42 
43  - differing face nlayers: 'termination' : (e.g. from 2 to 4 layers) match
44  at original patch face side.
45 
46  E.g. 2 boundary faces on patches a,b. 2 layers for a, 3 for b.
47 
48  \verbatim
49  Was:
50 
51  a b <- patch of boundary face
52  +------+------+
53  | | | <- original cells
54  +------+------+
55 
56  Becomes:
57 
58  a b <- patch of boundary face
59  +------+------+
60  + +------+
61  +------+------+
62  +------+------+
63  | | | <- original cells
64  +------+------+
65  \endverbatim
66 
67 
68  - added faces get same patchID as face they are extruded from
69  - 'side' faces (i.e. on the edge of pp) get the patchID/zoneID of the
70  other patch/zone they are connected to (hopefully only 1)
71 
72 
73  E.g. 3 boundary faces on patches a,b. b gets extruded, a doesn't.
74 
75  \verbatim
76  a b b <- patch of boundary face
77  +------+------+------+
78  | | | | <- cells
79  +------+------+------+
80 
81 
82  ^ ^ <- wanted extrusion vector (none at far right)
83  a | b | b <- patch of boundary face
84  +------+------+------+
85  | | | | <- cells
86  +------+------+------+
87 
88  b
89  +------+\ b 1. prism cell added onto second b face since
90  a a| | ----\ only one side gets extruded.
91  +------+------+------+ 2. side-face gets patch a, not b.
92  | | | |
