Class
    Foam::patchToFace
 
Description
    A \c topoSetFaceSource to select cells associated with given patch(es).
 
    Operands:
    \table
      Operand   | Type    | Location
      output    | faceSet | $FOAM_CASE/constant/polyMesh/sets/<set>
    \endtable
 
Usage
    Minimal example by using \c system/topoSetDict.actions:
    \verbatim
    {
        // Mandatory (inherited) entries
        name        <name>;
        type        faceSet;
        action      <action>;
 
        // Mandatory entries
        source      patchToFace;
 
        // Conditional mandatory entries
        // Select either of the below
 
        // Option-1
        patches
        (
            <patchName1>
            <patchName2>
            ...
        );
 
        // Option-2
        patch    <patchName>;
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property   | Description                         | Type | Req'd | Dflt
      name       | Name of faceSet                     | word |  yes  | -
      type       | Type name: faceSet                  | word |  yes  | -
      action     | Action applied on faces - see below | word |  yes  | -
      source     | Source name: patchToFace            | word |  yes  | -
    \endtable
 
    Options for the \c action entry:
    \verbatim
      new      | Create a new faceSet from selected faces
      add      | Add selected faces into this faceSet
      subtract | Remove selected faces from this faceSet
    \endverbatim
 
    Options for the conditional mandatory entries:
    \verbatim
      Entry    | Description           | Type     | Req'd  | Dflt
      patches  | Names of patches      | wordList | cond'l | -
      patch    | Name of patch         | word     | cond'l | -
    \verbatim
 
Note
    The order of precedence among the conditional mandatory entries from the
    highest to the lowest is \c patches, and \c patch.
