This manuscript presents the simulation of the Fluid Structural Interaction (FSI) of a cantilever
compliant panel in hypersonic flow. The problem is resolved through multiphysics coupling in the
commercial software package LS-DYNA and employs the use of the Immersed Boundary Method (IBM)
within the Conservation Element Solution Element (CESE) solver framework using explicit time stepping.
The CESE method encompasses many non-traditional features that makes it aptly suited for the study
of hypersonic flows, including, a unified treatment of space and time, and a Riemann-free shock solver.
The study of hypersonic FSI is of high importance due to restrictive weight requirements resulting in
thin panels that are prone to deformation. The understanding of the aeroelastic effects is important to
ensure continued operation of geometry sensitive regions such as inlets and control surfaces.
