connector or contactsurf when joining a solid component with shell (composite) elements

Hi,

im not sure whether to define a connector or contact surface between a shell and solid element.

when i add a connector, i get a failed projection, and when i try with contact surfaces i get a missing property error. any suggestions?

Hi,

Can you try with Rigids?

Hi Prakash,

Thank you for your suggestion. i was able to establish a joinedconnection.

i have now added an axial pretension of 1N, (although it needs to be a 1000N) to the 3d beam and am getting an infinite displacement. Im assuming this is because i have an under constrained the curved structure. However, is there way to constrain the structure so that there is no positive y displacement, but only negative.

In the real application, a positive pretension actually causes negative displacement. The application is a bicycle wheel and my approach was to use cyclic symmetry to create a smaller model. Would you have any ideas?
