Abstract: A simulation method includes: a step of setting a heating condition of an object; a step of calculating a first estimated temperature as a temperature of a central portion of the object, based on the heating condition; and a step of calculating a second estimated temperature as a temperature in a second area that surrounds a first area positioned in the central portion of the object, based on the first estimated temperature.

Abstract: In a heating simulation method, a first physical property value and a second physical property value are set as a physical property value of an object to be heated, a temperature at which the physical property value of the object changes from the first physical property value to the second physical property value is set as a conversion temperature, the temperature change of the object is calculated using the first physical property value as the physical property value of the object in the case where a calculated temperature of the object is lower than the conversion temperature, and the temperature change of the object is calculated using the second physical property value as the physical property value of the object in the case where the calculated temperature of the object is equal to or higher than the conversion temperature.
