PROBLEM TO BE SOLVED: To provide a drying oven analysis program by which a numeric analysis on fluid for a hot air in a drying oven can be carried out in a short time by calculating a boundary condition necessary for the analysis by a simple method. SOLUTION: In order to analyze an internal state of the drying oven in which an object containing water is set to be dried by the dried hot air, the boundary condition between a minute area of a surface of the object to be dried and the hot air of a minute volume in contact with the minute area is calculated by sorting to two kinds by a water content of the object. When the water content of the object is not smaller than a limit level, the boundary condition is calculated by considering that a material flux of evaporated water in terms of a heat quantity is equal to an entering heat flux between the minute area and the minute volume. When the water content of the object is not larger than the limit level, the boundary condition is calculated by considering that a relation between the water content and a drying speed is expressed by a function. The calculated boundary condition is applied to the numeric analysis on fluid for the hot air, whereby the behavior of the hot air is analyzed.
