Class
    Foam::faceToCell
 
Description
    A \c topoSetCellSource to select all cells based on usage in given
    \c faceSet(s), e.g. select cells that are the \c owner/neighbour/any
    of the faces in a given \c faceSet.
 
    Operands:
    \table
      Operand   | Type       | Location
      input     | faceSet(s) | $FOAM_CASE/constant/polyMesh/sets/<set>
      output    | cellSet    | $FOAM_CASE/constant/polyMesh/sets/<set>
    \endtable
 
Usage
    Minimal example by using \c system/topoSetDict.actions:
    \verbatim
    {
        // Mandatory (inherited) entries
        name        <name>;
        type        cellSet;
        action      <action>;
 
        // Mandatory entries
        source      faceToCell;
        option      <option>;
 
        // Conditional mandatory entries
        // Select either of the below
 
        // Option-1
        sets
        (
            <faceSetName0>
            <faceSetName1>
            ...
        );
 
        // Option-2
        set     <faceSetName>;
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property   | Description                         | Type | Req'd | Dflt
      name       | Name of cellSet                     | word |  yes  | -
      type       | Type name: cellSet                  | word |  yes  | -
      action     | Action applied on cells - see below | word |  yes  | -
      source     | Source name: faceToCell             | word |  yes  | -
      option     | Selection type - see below          | word |  yes  | -
    \endtable
 
    Options for the \c action entry:
    \verbatim
      new      | Create a new cellSet from selected cells
      add      | Add selected cells into this cellSet
      subtract | Remove selected cells from this cellSet
    \endverbatim
 
    Options for the \c option entry:
    \verbatim
      all       | Cells that are either owner or neighbour of given faces
      any       | Cells that are either owner or neighbour of given faces
      owner     | Cells that are owner of given faces
      neighbour | Cells that are neighbour of given faces
    \endverbatim
 
    Options for the conditional mandatory entries:
    \verbatim
      Entry    | Description                | Type     | Req'd  | Dflt
      sets     | Names of input faceSets    | wordList | cond'l | -
      set      | Name of input faceSet      | word     | cond'l | -
    \verbatim
 
Note
    The order of precedence among the conditional mandatory entries from the
    highest to the lowest is \c sets, and \c set.
