Method for synthesizing analysis model and flow analysis system

A flow analysis system comprising:

• model interactive synthesizing means for dividing a shape into partial shapes by interactive process, for defining a feature amount in an interactive manner and for allocating an analysis model to a partial shape;
• log retainer means for retaining input information during interactive processing by said model interactive synthesizing means;
• know-how registration means for registering the relationship between a shape feature, which is know-how for constructing an analysis model, and an analysis model;
• know-how forming means for forming know-how registered in said know-how registration means, said know-how being effective for synthesization models;
• know-how being editing means for merging know-how already registered in said know-how registration means and know-how formed by said know-how forming means while avoiding occurrence of contradiction between the know-how;
• and model synthesizing means for synthesizing flow analysis models for analyzing the entire flowpassage, wherein even with respect to an object in which flow analysis models cannot be synthesized in terms of relationship between the already registered shape feature and the analysis model in said model synthesizing means, the flow analysis models can be synthesized by once subjecting them to interactive processing.

In a system for calculating a flow state material to evaluate a flowpassage shape, a flow control condition, and material, a flow analysis system comprising:

• experimental data registration means for registering experimental data relating to a material characteristic;
• characteristic formula defining means for defining a characteristic formula representative of said material characteristic;
• difference appraisal formula defining means for defining an appraisal formula to numerically evaluate a difference between experimental data register by said experimental data registration means and a value produced by the characteristic formula defined by said characteristic formula defining means;
• difference appraisal means for computing the difference between the experimental data and the value produced by the characteristic formula using said appraisal formula;
• and parameter correction amount computation means operating on the basis of a characteristic formula for computing the correction amount of parameters, peculiar to the material determined from the experimental data, from the difference computed by said difference appraisal means, wherein the flow analysis with respect to material whose characteristic changes with hysteresis is carried out.
