Provided is a method of simulating various viscoelastic fluids having viscosity, elasticity, and plasticity, based on smoothed particle hydrodynamics (SPH), which is widely used in fluid simulation using particles. Artificial forces related with viscosity, elasticity, and plasticity are added to address fundamental numerical limitations of a SPH method due to use of particle approximation and to improve expression of characterized motions of a viscoelastic fluid. Since the artificial forces are added, and parameters are adjusted according to the adding of the artificial forces, a fluid can be realistically expressed, and the control of a fluid motion is facilitated.
