Method, apparatus and system for incompressible fluid simulations, and storage medium storing program for executing the method

An apparatus for incompressible fluid simulations, comprising:

• a particle attribute calculating unit for calculating force acting on each particle forming a fluid;
• an incompressible condition calculating unit for calculating a velocity field satisfying a incompressibility condition of the fluid based on the calculated force;
• and
• a moving unit for moving the particle in the velocity field.

A system for incompressible fluid simulations, comprising:

• a computer-readable storage medium storing a program for executing, on a computer, a method including:
• calculating a force acting on each particle forming a fluid;
• calculating a velocity field satisfying a incompressibility condition of the fluid based on the calculated force;
• and
• moving the particle in the calculated velocity field;
• a computer for reading out and executing the program stored in the storage medium;
• a display for visually displaying results executed on the computer.
