Abstract

The present invention is applied to the design of a mold for a semiconductor or the like and provides a method for synthesizing analysis models, in which analysis programs corresponding to shapes and features of an object to be analyzed are registered in advance in a numerical analysis system, the analysis programs are made to correspond to partial shapes divided according to the shapes and features of the object to be analyzed and are partially modelled, whereas input and output items between adjacent portions are controlled on the basis of the positional relationship between the portions and input and output information of the analysis programs placed in correspondence to the portions. The invention further provides a flow analysis system for computing a flow state of material to evaluate a shape of a flowpassage, a flow control condition, material and the like, the system comprising input means for inputting a flowpassage shape of a mold, properties of material and flow control conditions, model synthesizing means for extracting a feature of the flowpassage shape, judging an adaptability with the already registered analysis model from the extracted features and synthesizing flow analysis models capable of analyzing the entire flowpassage, and program execution means for removing programs corresponding to the synthesized model to sequentially execute them.
