This case is an extensive benchmark problem featuring a rolling tank with an elastic plate in between. The oscillations of the plate are studied. Due to the extensive computational time required in order to study this problem, it is frequently presented in 2D. However, the version offered here is in 3D, highlighting the powerful capabilities of the solver in handling mesh movement and remeshing as well as strong coupling fluid structure interaction. 32 CPUs or more are recommended in order to run this problem.
