Class
    Foam::clipPlaneToPoint
 
Description
    A \c topoSetPointSource to select all points
    above the specified plane
 
    Operands:
    \table
      Operand   | Type     | Location
      output    | pointSet | $FOAM_CASE/constant/polyMesh/sets/<set>
    \endtable
 
Usage
    Minimal example by using \c system/topoSetDict.actions:
    \verbatim
    {
        // Mandatory (inherited) entries
        name        <name>;
        type        pointSet;
        action      <action>;
 
        // Mandatory entries
        source      clipPlaneToPoint;
 
        point  (x y z);
        normal (x y z);
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property   | Description                         | Type | Req'd | Dflt
      name       | Name of pointSet                    | word |  yes  | -
      type       | Type name: pointSet                 | word |  yes  | -
      action     | Action applied on points - see below| word |  yes  | -
      source     | Source name: clipPlaneToPoint        | word |  yes  | -
    \endtable
 
    Options for the \c action entry:
    \verbatim
      new      | Create a new pointSet from selected points
      add      | Add selected points into this pointSet
      subtract | Remove selected cells from this pointSet
    \endverbatim
 
    Options for the conditional mandatory entries:
    \verbatim
      Entry    | Description                        | Type   | Req'd  | Dflt
      point    | The reference point for the plane  | vector | yes    | -
      normal   | The unit normal of the plane       | vector | yes    | -
    \endverbatim
