sending a picture of how the structure looks like, and how the forces should be put...
this kind of loading leads to that the top of the cylinder deforms...but with the mentioned way of connekting the loadingpoint makes it stiff...
thanx, yes thats right.. i have tried the way you proposed, but it doesnt behave as i want it to do. That kind of coupling makes the nodes on the circular surface rigid, and this is not how the reality appears.
Only the rotations are wanted to be equal, but there comes up an error when trying...
I wonder how to apply a bending moment in the center of a cylinder.
I guess some form of coupling and connector have to be made, but dont know how to do it?
The moment should be applied in the axissymmetric axis.
Please help!
