Hi

Two things here to start.

 

  1. We can not have 2D geometry in harmonic acoustics or coupled field harmonic – so these systems are only for 3D analysis and thus need a 3D geometry.
  2. Set the material to water or air for acoustic domain and say steel (or material as needed) for structural under the geometry before defining the physics regions

 

All the best
