Abstract: When the temperature history in a fine mesh is obtained for the entire modeled object, it takes a huge amount of time in calculation. In order to solve the problem, An additive-manufactured object design supporting device, comprising: an analysis unit configured to analyze a modeling process of a macro-region and a micro-region by using a product shape, a material condition, and a modeling condition of a modeled object as input; a temperature history extraction unit configured to extract, from a temperature analysis result of the macro-region, a local temperature history by referring to a database that stores a temperature history of the micro-region; a mapping unit configured to map a structure distribution obtained from a temperature history distribution of the modeled object to the modeled object; and an extraction unit configured to extract a defective structure that does not satisfy a structure condition by using an allowable structure condition as input.
