PROBLEM TO BE SOLVED: To provide a shape simulation device in which simplification of shape simulation and accuracy improvement can be compatible, and to provide a shape simulation method, and a shape simulation program.SOLUTION: A shape simulation device according to an embodiment includes a shape setting unit for setting the shape of a material in a calculation region at N times T-T(N is an integer of 2 or more). The device further includes a time evolution calculator performing time evolution of shape of the material independently at the times T-T, and calculating first through N-th values representing the change in shape of the material, respectively, from the time T-Tto the time T'-T'. The device further includes a shape calculator for calculating shape of the material at a time T, on the basis of the first through N-th values.SELECTED DRAWING: Figure 1
