24 Class
25  Foam::fvCellSet
26 
27 Description
28  General run-time selected cell set selection class for fvMesh
29 
30  Currently supports cell selection from:
31  - a set of points
32  - a cellSet
33  - a cellZone
34  - all of the cells.
35 
36 Usage
37  Examples:
38  \verbatim
39  // Select all cells
40  select all;
41 
42  // Select the cells within the given cellSet
43  select cellSet; // Optional
44  cellSet rotor;
45 
46  // Select the cells within the given cellZone
47  select cellZone; // Optional
48  cellZone rotor;
49 
50  // Select the cells containing a list of points
51  select points; // Optional
52  points
53  (
54  (2.25 0.5 0)
55  (2.75 0.5 0)
56  );
