Case 1: 3D Acoustic-Solid Interaction
This model simulates the acoustic-solid interaction between a solid block immersed in water and exposed to a sound signal. The acoustic pressure (sound) interacts with the solid and moves the walls, which in turn push on the water thereby set up additional sound waves. The frequency response from the structure is calculated, which is then fed back to the acoustics domain so that the wave pattern can be analyzed. This two-way coupling is set up. The "Pressure Acoustics, Frequency Domain" physics type is defined for the water, and the surfaces of the solid block are defined as "Acoustic-Structure Boundary".
