Dear all,

I use DFBI Morphing to simulate the roll motion and heave motion in the same time, however, when I chose DFBI → free motion → roll motion and heave motion and monitor them, I found that there was only heave motion, but no any roll motion (no rotation angle was detected).

So next, I just chose free motion → roll motion only, and also there was no rational angle was shown. But, after I changed the "free motion" into just only "one-DOF of rotation", there was a rotation angle that can be detected. So I am wondering why this happens and are there something wrong with DBFI Morphing with Free Motion? Or I set up something wrong?
