Abstract
The present invention provides an apparatus and method for analyzing a process of fluid flow such as an injection molding process within a practical computing time using a three-dimensional model divided into a plurality of small elements to represent a cavity in which a fluid flows, and provides also an apparatus and method for analyzing an injection molding process, an injection molded product, and a method for producing an injection molded product. The apparatus and method for analyzing a process of fluid flow of the present invention comprises constructing a three-dimensional model divided into a plurality of small elements to represent a cavity in which a fluid flows, determining the flow conductances .kappa. based on the flow thicknesses in the cavity, and computing pressures, pressure transitions or flow velocities at the respective small elements based on the flow conductances.
