24 Class
25  Foam::sampledSurfaces::plane
26 
27 Description
28  A sampledSurface defined by a plane which 'cuts' the mesh using the
29  cuttingPlane algorithm. The plane is triangulated by default.
30 
31  Example:
32  \verbatim
33  {
34  type plane;
35  planeType pointAndNormal;
36  point (0 0 0);
37  normal (0 0 1);
38  interpolate yes;
39  }
40  \endverbatim
41 
42 Usage
43  \table
44  Property | Description | Required | Default value
45  planeType | the method of specification of the plane | yes |
46  triangulate | triangulate the output | no | yes
47  interpolate | interpolate values to the surface points | no | no
48  \endtable
