We investigated the deformation of a soft structure filled with a liquid in a uniform flow by solving a coupled problem. The liquid inside was the same as that of the outer flow in this study. The soft object was modeled by a circular cylinder whose surface was made of a network of mass-spring-dumper system to represent its mechanical characteristics. The soft structure was deformed from the circular cylinder due to inside and outside forces acting on the surface. We found that the soft structure became ellipse-like cylinder whose major axis was perpendicular to the main flow direction. The ellipticity depended on the value of the spring constant or damping coefficient. We discussed the effects of a spring constant and damping coefficient on the deformation.
