To accurately estimate a mechanical characteristic of each of parts of die casting.SOLUTION: A die model for a CAE analysis is formed by dividing a cavity of a die for obtaining a casting into a plurality of elements. Using the die model, a metal flow analysis and a solidification analysis are carried out under a predetermined casting condition. A factor relating to a growth of a solidification structure, a factor relating to a degree of cleanliness of molten metal, and a factor relating to a cavity defect are calculated for each of the elements described above. A mechanical characteristic for each part of the casting described above is obtained by a regression formula using a multiple regression analysis in which a mechanical characteristic of the casting is a target variable and each of the factors is an explanatory variable.SELECTED DRAWING: Figure 5
