An immersed boundary-lattice Boltzmann flux solver is proposed in the ALE framework for 3D freely falling problems; It extends the applicability of fixed grid-based IBMs and reduces considerable computational efforts; As compared with conventional ALE approaches, the re-meshing process is avoided; It considers the fluid-structure interactions with six degree of freedom. It is successfully applied for simulating 3D freely falling disk in an open flow domain, which seems to be the first work by IBM.
