摘要： A fluid structure interaction simulation method includes a graph information forming process to form graph information of nodes obtained by discretising 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.
