Shell to shell constrains

[erselvasajitha]

I have been modelling a steel corrugated sheet which is held by a carrier which just hold sheet by a hook like projection in it. Then this carrier held by a rod which i modelled as wire element. Carrier and sheet I have modelled as shell element. Sheet will have z like at both ends that is hold by closed arrow shaped carriers. Pls explain about how I need to provide constraints

 

[FEA way]

Can you share a screenshot or at least rough drawing of your model ? Such connections are usually achieved with tie constraints or contact.
