Description

This FSI case is an expansion of the two-phase shock bubble example and add a flexible structure (baffle) to the problem. In this test case, a left moving shock wave propagates and first hits a stationary bubble, which gains speed and loses its circular shape. After the shock wave hits the bubble, the created circular pressure waves keep moving forward and hit the structure panel causing its deformation. A 2D and 3D version of the problem are provided.
