ABSTRACT:
A simulation system predicts a behavior of a molten resin in a mold in filling, packing, and cooling processes by using a fundamental equation formulated by the finite element method, and shrinkage factors in a direction of thickness and planar directions based on anisotropy of a volume shrinkage factor obtained during prediction of the filling, packing, and cooling processes, so that a warp deformation in an injection-molded article can be predicted at a higher precision. In this simulation system, the warp deformation is predicted by calculating the shrinkage factors in accordance with:
