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 fluid-structure 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. Mooney-Rivlin material. The present method is confirmed to well capture the solid deformation.
