Class
    Foam::rotatedBoxToCell
 
Description
    A \c topoSetCellSource to select cells based on cell centres
    inside a given parallopiped (i.e. rotated/skewed box).
 
    Operands:
    \table
      Operand   | Type     | Location
      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      rotatedBoxToCell;
        origin      (<o1> <o2> <o3>);
        i           (<i1> <i2> <i3>);
        j           (<j1> <j2> <j3>);
        k           (<k1> <k2> <k3>);
    }
    \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: rotateTedBoxToCell     | word |  yes  | -
      origin     | Origin of the box                   | vector | yes | -
      i          | x1-axis                             | vector | yes | -
      j          | x2-axis                             | vector | yes | -
      k          | x3-axis                             | vector | 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
 
    Box defined as origin and i,j,k vectors.
    For example, box rotated 45 degrees around z-axis with
    sizes sqrt(0.2^2+0.2^2) (and extra large, 200 in z direction):
    \verbatim
      origin   ( 0.4 0.4 -100);
      i        ( 0.2 0.2  0);
      j        (-0.2 0.2  0);
      k        ( 0.0 0.0  200);
    \endverbatim
