Heating simulation method, heating simulation program, and heating simulation device including storage medium having said program stored therein

A heating simulation program for causing an arithmetic unit to execute calculation of temperature change of an object to be heated under a predetermined heating condition, the heating simulation program causing the arithmetic unit to execute:

• a step of receiving settings of a first physical property value and a second physical property value as a physical property value of the object to be heated;
• a step of receiving a setting of a temperature at which the physical property value of the object to be heated changes from the first physical property value to the second physical property value, as a conversion temperature;
• a step of determining whether a calculated temperature of the object to be heated is equal to or higher than the conversion temperature;
• a step of calculating the temperature change of the object to be heated using the first physical property value as the physical property value of the object to be heated, in the case where the calculated temperature of the object to be heated is lower than the conversion temperature;
• and
• a step of calculating the temperature change of the object to be heated using the second physical property value as the physical property value of the object to be heated, in the case where the calculated temperature of the object to be heated is equal to or higher than the conversion temperature.
