摘要： A fluid structure interaction simulation method includes a graph information forming process to form graph information of nodes obtained by discretizing a computing region for each of a fluid and a structure that are represented by meshes, and a main time development loop process to simulate a physical phenomenon. The loop process includes arranging IMEs (Interaction Mediating Elements) that move with a displacement of the structure, on a boundary of the structure, defining, within the IME, correcting functions of a pressure and a velocity of the fluid that interact with the pressure and the velocity of the fluid and the displacement of the structure, and executing a simulation based on the correcting functions, in a state in which the meshes of the fluid are mismatched to the meshes of the structure.

摘要： A stress estimating system includes a polygon data input unit of polygon data modeling a vascular wall, an interactive analysis condition setting unit for setting the tensile force acting on the vascular wall boundary, blood pressure and constraint estimated as proper on the boundary, a stress analysis unit for obtaining two-dimensional stress by solving a mechanical equilibrium equation with respect to the membrane stress on a curvilinear surface of the vascular wall under the condition given by the polygon data input unit and the interactive analysis condition setting unit, and an interactive visualization unit for displaying a distribution of a stress component designated by a system user. Without assuming any symmetry for the curvilinear configuration and stress distribution, a complicated stress distribution is estimated only out of the mechanical equilibrium equation with respect to membrane stress.
