Rotating thin plate while fixing one end to twist it

I want to use Comsol to simulate a rotation of very thin and long plate (x:50,y:1,z:500 & rotation axis : z) deformed into a twisted structure. Maybe, I can define geometry with symmetry axis or not... anyway the point is that I can't model such a rotation with Solid mechanics or Multi body dynamics.
I input "prescribed diplacement" with x and y direction as a zero to fix one end (edge at z=0),
and "rigid connector" with prescribed rotation at center of rotation as omega (0,0,1) and 180[deg] to rotate the other end (edge at z=500). But, it ended with following error.
Failed to find a solution.
The relative error is greater than the relative tolerance.
Returned solution is not converged.
Do you think it is related with material properties or the physical constraints?
Welcome to find any comments on this problem.
Thanks.
