I suspect the 1 degree rotation isn't helping as you'll have a very skew cell at the axis. Try with a 30 degree sector. However, unless you model the full 360 zone I'd expect 2d-axi and the 3d sector to be near enough identical. The only reason a full model may differ is when the jet isn't stable and a lack of constraints will allow it to move if it's inclined to do so.Â
