Kimematic Coupling

[aliasgere]

I am modelling a 3D cylindrical shell embedded in solid elements around it. At the top of the cylinder at the centre, I have kinematically coupled the reference point to the shell surface and applied vertical load, horizontal load and a horizontal moment at the reference point, for transfer to the cylinder. When I analyse the bending moment profile of the cylinder, I observe that the bending moments are higher than would be from the the applied load. I wonder if it is due to having all degrees of freedom unconstrained for the kinematic coupling?

I shall highly appreciate it if someone can give me some guidance on what DOF constraints I should be applying?

Kind regards,
