I am trying to permanently connect a shell with an irregular shape (made of steel) to another rigid shell in LS-Dyna.

Can someone help me?

I have tried different contact types, but did not manage to solve it.

Thanks

Hello,

Rigid bodies cannot be included in a constraint-based contact, only tied contacts that are penalty based can be used with rigid bodies.

You could use *CONSTRAINED_EXTRA_NODES_OPTION that will allow you to constrain an edge of a shell (made of metal) to the rigid shell in your model.

Please let me know how it goes.

Thank you,

Alex
