An Eulerian Approach to Fluid-Structure Coupling Problems Suitable for Voxel-Based Geometry
(0) A new simulation method for solving fluid-structure coupling problems suitable for voxel-based geometry has been developed. All the basic equations are numerically solved on a fixed Cartesian grid in a finite difference scheme. An incompressible fluid flow solver is extended to the incompressible fluidstructure system. A volume-of-fluid approach is applied to describing the multi-component geometry. The temporal change in the solid deformation is described on the Eulerian frame by updating a left Cauchy-Green deformation tensor, which expresses constitutive equations of the hyperelastic Cauchy stress for e.g. neo-Hookean material. Two validations are made: one is a comparison with the available simulation of the solid motion in the lid-driven flow (Zhao et al. (2008) J. Comput. Phys. 227, 3114), in which the deformed solid motion is solved in the finite element approach, the other is an examination of the reversibility in shape of the hyperelastic material under no stress situation. The present method is confirmed to well capture the material deformation and the reversal.
