In numerical simulation of Fluid-Structure interaction (FSI) by a weak coupling system, a FLUENT software for a flow analysis and a MSC. Marc software for structural analysis are used. The weak-coupling system is the method that equations for a flow field and a structural field are solved separately. In this FSI system, a flow field is unsteady and another structural field is assumed as quasi-steady. Data of pressure and shear stress distributions and deformations are given each other as the boundary conditions on the surface of the body. Mechanical properties of materials, muscle, fat and skin for the human body are selected from the database of RIKEN in Japan. Various values of these mechanical properties are tried as the parameter study. Since deformations of materials are small, relations between stress and strain are linear Hook’s laws. Periodic fluid forces acting a surface of a human body are induced vibration of internal structure of the abdomen.
