STREAMLINE VISUALIZATION APPARATUS, STREAMLINE VISUALIZATION METHOD, AND STREAMLINE VISUALIZATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To enable tracking of a streamline even when a structure changes.SOLUTION: A processing part 12 calculates each of time differential values of a plurality of velocities of fluid at a plurality of first times on a plurality of grid points V1 to V4 using a formula including a correction value to correct errors caused by acceleration motions of the plurality of the grid points V1 to V4 indicated in position information. Next, the processing part 12 calculates each of a plurality of positions of a plurality of particles sequentially output from a particle source with proceeding of analysis time at a plurality of second times at a second time interval which is shorter than a first time interval based on each of velocities and time differential values of the velocities of the fluid on the plurality of grid points V1 to V4 at the plurality of first times. Then the processing part 12 generates display information of a streamline indicating continuity of the plurality of the particles.SELECTED DRAWING: Figure 1
