ABSTRACT:
An evaluation method of a flow analysis on molding of a molten material is achieved in a system of performing a flow analysis on an in-mold molten material through breakdown of a molded part model into minute elements and numerical analysis thereof including the calculi of finite elements, boundary elements, finite differences, FAN and the like. One or more temperature conditions of the molten material are provided with a plurality of loading times respectively for conducting an analysis and from the obtained operational results of the temperature distribution of the molten material after loading, an average temperature or a medium layer temperature of each element is calculated as a function Tn=fn(t) having a variable of the loading time. This function is graphically indicated on a display apparatus to determine the ranges of the molten material temperature and the loading time at a predetermined mold temperature.
