摘要
A fluid-structure coupled numerical simulation method is provided. The method uses a finite volume method employing an orthogonal mesh and a computer and memory setting a solid area based on a solid rate inside a mesh and at a tangent position to each mesh, including the steps of: setting initial and boundary conditions of a moving film structure; setting a velocity boundary in the tangent direction of the film structure by computing a position and shape thereof; and computing a curvature thereof. The method further includes the step of computing a pressure balance based on a balance between a pressure obtained from a fluid computation and a repulsive force obtained from the tension and curvature of the film structure to implement processing of a mutually-coupled phenomenon. A shift amount of the film surface for each time of said computing steps is simulated using the same program.
