how to applying Torque onto ellipsetical tube by using rigid regions

[Chomtid]

Having a hard time in applying torque on ellipsetical tube? I don't know using rigid regions is a correct choice or not. I Have been running this test through the below command for a week. Hope anyone can take me out of the darkness.
