PROBLEM TO BE SOLVED: To provide a simulation program of heat treatment, which has a reduced analysis time.SOLUTION: Simulation of heat treatment in which a workpiece is subjected to induction heating while the workpiece is moved around an axis or along a shape of the workpiece relative to a heating coil or the heating coil is moved around the axis or along the shape of the workpiece relative to the workpiece includes: a magnetic field analysis step (STEP2) of obtaining a distribution of heat generation densities occurring in the workpiece due to induction heating in a state where the workpiece is fixed relative to the heating coil; and a heat treatment analysis step (STEP3) of computing a heat generation density distribution at the time of a trace of movement of the workpiece around the axis or along the shape of the workpiece relative to the heating coil, by rotating the heat generation density distribution obtained in the magnetic field analysis step around the axis or moving it along the shape of the workpiece, and obtaining a temperature distribution of the workpiece each time when computing the heat generation density distribution. |
