Class
    Foam::sampledPatch
 
Description
    A sampledSurface on patches. Non-triangulated by default.
 
    This is often embedded as part of a sampled surfaces function object.
 
Usage
    Example of function object partial specification:
    \verbatim
    surfaces
    {
        surface1
        {
            type    patch;
            patches (inlet "outlet.*");
        }
    }
    \endverbatim
 
    Where the sub-entries comprise:
    \table
        Property | Description                             | Required | Default
        type     | patch                                   | yes      |
        patches  | patch selection as word/regex list      | yes      |
        triangulate | triangulate faces                    | no       | false
    \endtable
