Hi,
Is there any possible ccx set up to bend a strip as it’s shown on the picture?
Cantilever subjected to end bending moment
Ccx seems unable to go beyond 90º.

Have you seen this example by M. Kraska ? CalculiX-Examples/Streifen at master · calculix/CalculiX-Examples · GitHub
Mr. Kraska also struggled close to 90º and he tries solving with mean rotation MPC’s, Rigid Body and kinematic coupling.
One end is rotated, and the incremental time becomes too small, and the solution is stopped at different percentages.
I have completed the rotation but it’s not a standard nor elegant way at all.
Appling a Moment as it is solved in the paper seems like 90º is a limit condition¿?.
It is part of a series of nice and challenging benchmarks, and I’m stuck with this one.
This is also interesting: Large rotation shell benchmark test - #2 by vicmw - CalculiX (official versions are on www.calculix.de, the official GitHub repository is at https://github.com/Dhondtguido/CalculiX).
That seems to be the same benchmark and was my first motivation. I saw a picture in Victor’s manual that was promissing but…didn’t completely work.
There is also a file posted in his forum and I tried to push up to the full rotation without exit.
Sems like the moment is converted into a force which is not a follower so initial forces pointing in the vertical direction doesn’t allow the strip to keep rotating.
I guess if someone managed to get it here. 
I think that Victor suggested Dload. Is Dload a follower force?
But Dload is perpendicular to the surface. I can’t apply it to the lip.
