Class
    Foam::boxToFace
 
Description
    A \c topoSetFaceSource to select all faces
    whose face centre inside given bounding box(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      boxToFace;
 
        // Conditional mandatory entries
        // Select one of the below
 
        // Option-1
        boxes
        (
            (<minX> <minY> <minZ>) (<maxX> <maxY> <maxZ>) // box-1
            (<minX> <minY> <minZ>) (<maxX> <maxY> <maxZ>) // box-2
            ...
        );
 
        // Option-2
        box (<minX> <minY> <minZ>) (<maxX> <maxY> <maxZ>);
 
        // Option-3
        min (<minX> <minY> <minZ>);
        max (<maxX> <maxY> <maxZ>);
 
        // Option-4
        min  (<minX> <minY> <minZ>);
        span (<sizeX> <sizeY> <sizeZ>);
    }
    \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: boxToFace              | word |  yes  | -
    \endtable
 
    Options for the \c action entry:
    \verbatim
      new      | Create a new faceSet from selected cells
      add      | Add selected cells into this faceSet
      subtract | Remove selected cells from this faceSet
    \endverbatim
 
    Options for the conditional mandatory entries:
    \verbatim
      Entry    | Description                    | Type       | Req'd  | Dflt
      boxes    | Multiple bounding boxes        | vectorList | cond'l | -
      box      | A single bounding box          | vectors    | cond'l | -
      min      | Minimum point (single box)     | vector     | cond'l | -
      max      | Maximum point (single box)     | vector     | cond'l | -
      span     | Box width (single box)         | vector     | cond'l | -
    \endverbatim
 
Note
    The order of precedence among the conditional mandatory entries from the
    highest to the lowest is \c boxes, \c box, \c min-max or \c min-span pair
    (compatibility with \c searchableBox).
