摘要

PURPOSE: To provide an analysis device and an analysis method for analyzing the flowing process of a fluid including an injection molding process, an analysis device and an analysis method for the injection molding process, an injection molded product and a manufacturing method for the injection molded product by using a three-dimensional model composed of a cavity, in which a fluid is flowed, divided into fine elements and also using the practical computation time. ;CONSTITUTION: A three-dimensional model composed of a cavity in which a fluid is flowed into a number of very fine elements is constituted, and flowing conductance (k) is determined so that the very fine elements are of small value in the case that they are positioned close to a cavity wall, while the elements are of large value in the case they are positioned far away the cavity wall, and pressure and pressure variation or flowing speed for respective very fine elements are computed based on the flowing conductance.;COPYRIGHT: (C)1996,JPO
