PROBLEM TO BE SOLVED: To provide a simulation model useful for analyzing a fluidized state of a plastic material such as rubber or resin.SOLUTION: A method for simulating a plastic material is provided for calculating a fluidized state of the plastic material in a chamber using a computer and includes: a step S1 of setting a chamber model made by modeling the chamber using the finite number of elements; a step S2 of defining a material model made by modeling the plastic material; a step S3 of setting a gas phase model made by modeling air; and a step S5 of arranging the material model and a gas phase model in the chamber model so as to be intermixed and making flow calculation. In the material model, a viscosity of the plastic material is defined, and in the gas phase model, a viscosity larger than an actual viscosity of air is defined. |
