Abstract: A method and a system for simulating controllable multiphase gas, and a recording medium thereof are provided to fully represent an intention of an animator, control the multiphase gas to converge to several goal shapes, and facilitate extension by overcoming a weak point requiring too much operation time and showing only the motion facing the closest goal shape. A cell control value calculator(210) calculates the cell control value of each cell/goal shape. The cell control value is force, to a direction decreasing a distance between the multiphase gas and multiphase goal shapes(200) present in the random cell. A non-compressive condition calculator(240) calculates a velocity field satisfying the non-compressive condition of the multiphase gas by applying the cell control value to the non-compressive condition. A flow moving(250) part moves particles forming the multiphase game according to the velocity field. A particle control value calculator calculates the particle control value of each particle. The particle control value is the force, to the direction decreasing the distance between the particles and the multiphase goal shapes.
