24 Class
25  Foam::extendedCellToFaceStencil
26 
27 Description
28  Calculates/contains the extended cell-to-face stencil.
29 
30  The stencil is a list of indices into either cells or boundary faces
31  in a compact way. (element 0 is owner, 1 is neighbour). The index numbering
32  is
33  - cells first
34  - then all (non-empty patch) boundary faces
35 
36  When used in evaluation is a two stage process:
37  - collect the data (cell data and non-empty boundaries) into a
38  single field
39  - (parallel) distribute the field
40  - sum the weights*field.
