<p><P>PROBLEM TO BE SOLVED: To provide a simulation device capable of realizing the precise interface calculation of a liquid-vapor free interface required in simulation of the movement, deformation, split, bond, surface layer flow on solid surface, and in-trap/pipe flow and wave of droplets or bubbles at low cost. <P>SOLUTION: The distance from the liquid-vapor free interface is calculated in each calculation grid. When the distance is larger than a designated value, and the fluid rate or density of the grid obtained by calculating an advection equation by reserve solution generates an error by numerical diffusion, the differential value with a right value is moved in the liquid-vapor free interface direction, whereby the numerical diffusion is corrected. <P>COPYRIGHT: (C)2004,JPO</p> |
