摘要

A technique for generating a basic element for numerical analysis by grid-dividing a numerical analysis object comprising components. An allowable range of the aspect ratio of the basic element of each component can be set, grid division can be conducted depending on the situation, a sufficiently high analysis accuracy is ensured, and the times required for the grid division and the analysis can be shortened. The grid division method comprises a setting step (S13) of setting an allowable range of the aspect ratio of the basic element for numerical analysis of each component during data conversion, a cube division step (S14) of dividing each component into cubes in the allowable range of the aspect ratio to create a cube division model during the data conversion, and a grid division step (S22) of grid-dividing each component according to the cube division model and generating a basic element for numerical analysis.
