Abstract: A system includes a unit for dividing a model in mesh units; a unit for generating and displaying a child edge as a new edge from a parent edge obtained by dividing the model in mesh units; a unit for amending the displayed child edge into an optional form; a unit for obtaining correspondence between the parent edge and the amended child edge; and a unit for analyzing structure of an amended model form determined based on the obtained correspondence. With the configuration, a structural analysis can be quickly performed in a simple operation by dividing a model into mesh units, specifying a child edge of an optional curve in a parent edge, projecting the parent edge into the child edge, automatically computing the coordinates, and obtaining the optimum solution in a structural analysis based on the computation.
