Class
    Foam::extrudeModels::sector
 
Description
    Extrudes by rotating a surface around an axis
    - extrusion is opposite the surface/patch normal so inwards the source
      mesh
    - axis direction has to be consistent with this.
    - use -mergeFaces option if doing full 360 and want to merge front and back
    - note direction of axis. This should be consistent with rotating against
      the patch normal direction. If you get it wrong you'll see all cells
      with extreme aspect ratio and internal faces wrong way around in
      checkMesh
 
    The sectorCoeffs dictionary entries
    \table
        Property  | Description                             | Required | Default
        point     | A point on the axis                     | yes |
        axis      | Axis direction, normalized on input     | yes |
        angle     | Sector angle (degrees)                  | yes |
    \endtable
 
Note
    For compatibility, accepts the entry \c axisPt (1812 and earlier)
    as equivalent to \c point.
