24 Class
25  Foam::sampledSurfaces::patch
26 
27 Description
28  A sampledSurface on patches. Non-triangulated by default.
29 
30  Example:
31  \verbatim
32  {
33  type patch;
34  patches (walls);
35  triangulate no;
36  interpolate yes;
37  }
38  \endverbatim
39 
40 Usage
41  \table
42  Property | Description | Required | Default value
43  patches | the names of patches on which to sample | yes |
44  triangulate | triangulate the output | no | no
45  interpolate | interpolate values to the surface points | no | no
