PROBLEM TO BE SOLVED: To efficiently perform designing in the intake route of an internal combustion. SOLUTION: When the inner shape of the intake route is designed as a prestage of analyzing the motion of fluid in the intake route of the internal combustion, a specification value concerning the inner shape of the intake route is inputted, so as to generate 3D shape data of an intake port, based on the inputted specification value. A permissible error in predicting a fluid analysis result is selected. The specification value which is inputted in an input process is assigned to a prediction formula corresponding to the selected permissible error. Then, the prediction value of the fluid analysis result is introduced. COPYRIGHT: (C)2006,JPO&NCIPI
