Class
    Foam::zoneToCell
 
Description
    A \c topoSetCellSource to convert \c cellZone(s) to a \c cellSet.
 
    Operands:
    \table
      Operand   | Type        | Location
      input     | cellZone(s) | $FOAM_CASE/constant/polyMesh/cellZones
      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      zoneToCell;
 
        // Conditional mandatory entries
        // Select either of the below
 
        // Option-1
        zones
        (
            <cellZoneName0>
            <cellZoneName1>
            ...
        );
 
        // Option-2
        zone     <cellZoneName>;
    }
    \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: zoneToCell             | word |  yes  | -
    \endtable
 
    Options for the \c action entry:
    \verbatim
      new      | Create a new cellSet from selected cells
      add      | Add selected cells into this cellsSet
      subtract | Remove selected cells from this cellSet
    \endverbatim
 
    Options for the conditional mandatory entries:
    \verbatim
      Entry    | Description                | Type     | Req'd  | Dflt
      zones    | Names of input cellZones   | wordRes  | cond'l | -
      zone     | Name of input cellZone     | wordRe   | cond'l | -
    \endverbatim
 
Note
    The order of precedence among the conditional mandatory entries from the
    highest to the lowest is \c zones, and \c zone.
