RE: How to apply torque on ellipsetical tube in ANSYS

I don't know anything about ANSYS, but you may have better luck on the ANSYS forum.

Incidentally, the shape of your tube is elliptical, not ellipsetical.

RE: How to apply torque on ellipsetical tube in ANSYS

As a matter of interest, could you simply apply two equal and opposite forces to a stiff plate welded to the end of the tube?  The torque would be F*d where F is the force and d is the distance apart.
