curvature on a pipe

Dear SW community,

I'm trying to curve a cylindrical beam. For that, one end of the beam is fixed (in all three axis), in a line crossing the circumference, while the other end is fixed only in two axes, being thus, free to "slide". When running the simulation the terminal "free to move in one direction", does not move et al. For rectangular beam I saw that it is possible to use a roller on a flat surface beneath the beam, however, on a circular beam I'm not capable to do that. Is there any solution to solve this problem?


Thanks
