Claim One:
1. A method for generating a three-dimensional(x, y, z) animation model on a computer that simulates a fluid flow and displaying the simulated fluid flow on a three dimensional graphics display, comprising the steps of: (a) forming a two dimensional (x and y) representation grid that models a liquid fluid flow on a computer; (b) calculating pressure values, p, along the two dimensional representation grid, wherein the pressure values, p, are proportional to a third dimensional representation z, by solving differential equations that includes: p.sup.n+1.sub.i;j =(.DELTA..sup.1.sub.x u.sup.n+1.sub.i;j +.DELTA..sup.1.sub.y v.sup.n+1.sub.i;j)/.epsilon., where i, j are respective x, y mesh coordinates, n+1 represents next state, and ".epsilon." is a constant less than 1 and greater than 0; and ##EQU20## and where f means either u, v or p, u is velocity in the direction of the x axis represented as meter per seconds, v is velocity in the direction of the y axis represented as meter per seconds, p is the pressure of fluid represented as newton per square meter, and terms l and m are arbitrary mesh coordinates in two-dimensions; and (c) displaying the two dimensional(x, y) and three dimensional(z) representations on a graphics display, wherein an animated three dimensional model of the liquid fluid flow is formed.
