Abstract

A model creation portion having a obstacle in a space includes two creation portions, one is to separate them and another is to combine them which handles, as porous media, an obstacle in which narrow spaces are regularly arranged. A thermosets flow analysis portion includes two analysis portions to separate and combine them, each of them has a viscosity equation for thermosets. The space/obstacle separation analysis portion analyzes by combining the viscosity equation with conservation equations of mass, momentum and energy, and the space/obstacle combination analysis portion analyzes by combining the viscosity equation with a conservation equation directed to a shape simplified as porous media. Resin flow behavior is analyzed while data in an interface between two models is delivered to each other, to accurately predict filling behavior at the time of injecting resin of thermosets molded articles having the complex obstacles.
