PROBLEM TO BE SOLVED: To provide a technique which can inform of a magnitude of a fluid pressure required for spreading a pressurized fluid between the back surface of a material under a semi-solidifying condition and a mold for molding when a molded article with an aperture part whose back surface is inside is injection-molded. SOLUTION: An injection molding simulation computer 100 has a plurality of analyzing apparatuses 104-108, a plurality of data files 120-130, etc. A flow analyzing apparatus 104 executes flow analysis of a material by utilizing basic data. A deformation analyzing apparatus 106 executes deformation analysis of the material 50 under the semi-solidifying condition by utilizing the result of the flow analysis. Rigidity data file 126 stores rigidity data of the material. A rigidity analyzing apparatus 108 calculates a force applied on the mold 72 for molding by the back surface 54 caused by deformation of the material 50 under the semi-solidifying condition by utilizing the result of the deformation analysis, the rigidity data and restricting conditions.
