Hello,

my design work is related to real aerodynamics/optimization/simmulation. I am looking for a way to join wings or pitch elevators to aerodynamic bodys e.g. fuselages.

So far I have only been fairly successful with sweeps (red example in the attached file). I've seen people getting good/better results using e.g. blend but I wasn't able to reproduce anything like that. I end up with "calculation failed" all the time.

The typical example is the T-joint in the attached file which needs to be smooth and extend to the very end of the wing body for aerodynamic reasons.

What's the best way to do it? What are design considerations to avoid e.g. calculation problems?

S.
