PROBLEM TO BE SOLVED: To provide a flow analyzer for quantitatively evaluating a gas inclusion state.;SOLUTION: The behavior of the fluid injected in a mold is analyzed. The mold is divided into fine cells to set a cell model and various parameters including a flow speed vector and the like are arranged to the fine cells to construct an analyzing model to be analyzed (ST2). The motion of the fluid is analyzed and operated on the basis of a control formula showing the behavior of the fluid by numerical operation at every predetermined step (ST3, ST4). The evaluation value for evaluating the gas inclusion behavior of the fluid is calculated an the basis of the diffusion of a flow speed by an evaluation formula (ST8).;COPYRIGHT: (C)2005,JPO&NCIPI
