Sandwich panel - Solid & shell intercation

I am a new COMSOL user.
I am trying to model a sandwich panel maiden of a wood core and carbon fiber skin.

My idea is to model the core with solid and the skin as shell.
I have already read some topics about solid-shell interaction and I know I mus apply a prescribed displacement to the solid due to shell displacement.

The problem I am not really practice with COMSOL and I'd like some one explain me main steps to do it.

Thanks.
