Class
    Foam::sampledSurfaces::patch
 
Description
    A sampledSurface on patches. Non-triangulated by default.
 
    Example:
    \verbatim
    {
        type        patch;
        patches     (walls);
        triangulate no;
        interpolate yes;
    }
    \endverbatim
 
Usage
    \table
        Property     | Description             | Required    | Default value
        patches      | the names of patches on which to sample | yes |
        triangulate  | triangulate the output  | no          | no
        interpolate  | interpolate values to the surface points | no | no
    \endtable
