Eigen frequency of Sandwich plate

Hello,
I am calculating eigen frequencies of a sandwich plate, in which a viscoelastic core is sandwiched between two aluminum plates. I have modeled the aluminum plates as shell (structural mechanics module) and the viscoelastic core (solid mechanics, viscoelastic material module). However, I am getting an error which says as " Variables not coupled with any degrees of freedom ". I am attaching the model for your reference.
If anybody has any answer concerning this, I will happily appreciate.
