Information processing apparatus that adjusts analysis model and method for adjusting analysis model

An information processing apparatus comprising:

• a memory configured to store a first analysis model that represents an apparatus that includes a fan and a second analysis model that is more simplified than the first analysis model;
• and
• a processor configured to:
• compare a first attribute value that indicates an operating point of the fan in the first analysis model with a second attribute value that indicates an operating point of the fan in the second analysis model;
• change a plurality of aperture ratios for a plurality of apertures included in the second model according to a result of a comparison of the first attribute value with the second attribute value and according to a difference between an air quantity at each of the plurality of apertures and an air quantity at each of a plurality of apertures included in the first analysis model corresponding to the plurality of apertures included in the second analysis model, each of the plurality of aperture ratios representing a ratio of an area of an aperture of a component model included by the second analysis model to a surface area of the component model;
• generate a statistical energy analysis model based on the second analysis model, wherein the statistical energy analysis model is generated by combining a plurality of statistical energy analysis elements, a shape of each of the statistical energy analysis elements is a cuboid or a shape in which a plurality of cuboids are combined, a statistical energy analysis element generated at a position in the second analysis model at which the component model exists is provided with a name of the component model and of one of the plurality of aperture ratios changed according to the result of the comparing, and a statistical energy analysis element generated in a space portion in which no component models exist is provided with a name indicating a space;
• perform an acoustic analysis process for the apparatus that includes the fan by using the statistical energy analysis model and obtaining acoustic power transmitted from the fan to outside of the apparatus that includes the fan;
• and
• output the acoustic power as an analysis result of the acoustic analysis process.
