INJECTION MOLDING SIMULATION METHOD, INJECTION MOLDING SIMULATION APPARATUS AND INJECTION MOLDING SIMULATION PROGRAM

PROBLEM TO BE SOLVED: To provide an injection molding simulation method capable of estimating, evaluating and displaying flow mark-like appearance defect by finding out that a discontinuous distribution caused by the abnormal flow in the flow of a molten material flowing after the leading end of a flow can be extracted by observing the temperature distribution of the molten material at the point of time of completion of filling obtained from an injection molding simulation result, an injection molding simulation apparatus and an injection molding simulation program. SOLUTION: A calculation model, wherein the shape of a molded product is divided into fine elements, is formed, the temperatures of the molten material in the respective fine elements of the formed calculation model are calculated, the temperature distribution of the molten material at the time of completion of the filling of a mold with the molten material is calculated on the basis of the calculated temperatures of the molten material in the fine elements and the occurrence of a flow mark is estimated on the basis of the calculated temperature distribution.
