Class
    Foam::cylindrical
 
Description
    A local coordinate rotation.
    The cell based rotational field can be created in two ways:
 
    1)  Each rotational tensor is defined with two vectors (dir and e3)
        where dir =  cellC - origin and e3 is the rotation axis.
        Per each cell an axesRotation type of rotation is created
        (cylindrical coordinates)
 
        \verbatim
            cylindrical
            {
                type        localAxes;
                e3          (0 0 1);
            }
        \endverbatim
 
    2) The rotational tensor field is provided at construction
