<p><P>PROBLEM TO BE SOLVED: To provide a method and a device for handling the motion boundary of a multicell computer model in a fluid dynamic system. <P>SOLUTION: The model having a fixed geometric grid as a base includes a step of identifying cells in the grid adjacent to a motion plane at the beginning of a transient time step, a step of identifying a beginning adjacent cell boundary formed in the grid with the motion plane, and a step of calculating a flux of an effective thermophysical value passing through the beginning cell boundary in the beginning adjacent cell in accordance with the motion direction of the motion plane, as well as a step of using the calculated effective flux for solving a transport equation regarding all cells to determine the thermophysical value for the cell at the ending of the time step, and a step of reforming the grid to follow the ending motion plane in the time step. The device includes a digital computer which is programmed to carry out the above method. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
